The criminal justice system is central to formal social control because its institutions detect crime, punish offenders and attempt to rehabilitate them. However, sociologists disagree about whether the system reduces crime, treats social groups equally or simply reflects wider inequalities. This criminal justice system and other agencies A-Level Sociology revision page also examines multi-agency crime control, where organisations such as the police, social workers, teachers and doctors work together. It brings together ideas from crime control [Crime control], punishment [Punishment] and victimisation [Victims of crime].

Revision Notes 📚
The criminal justice system and other agencies A-Level Sociology revision
AQA requires students to study the role of the criminal justice system and other agencies alongside crime control, surveillance, prevention, punishment and victims.
This lesson is therefore the final part of the Crime and Deviance content and draws together many ideas studied earlier in the unit.
The central sociological questions are:
What functions does the criminal justice system perform?
Does detecting and punishing crime necessarily reduce it?
How effectively are offenders rehabilitated?
Does the criminal justice system treat different social groups equally?
Does formal social control reinforce shared values or unequal power?
What contribution can agencies outside traditional criminal justice institutions make?
Can cooperation between several agencies reduce the risk of offending?
AQA assessed the role of the criminal justice system directly in 2025. The item stated that criminal justice institutions exist to detect crime and that the system is responsible for punishing and rehabilitating offenders.
What is the criminal justice system?
The criminal justice system, often abbreviated to CJS, refers to the institutions and processes involved in formally responding to crime.
Within the supplied AQA material, three central roles are especially clear:
detecting crime;
punishing offenders;
rehabilitating offenders.
Earlier AQA mark schemes also identify broader social functions including:
deterrence;
restitution;
reinforcing shared values;
protection of the public;
control of the working class;
reinforcing patriarchy;
employment within criminal justice institutions.
The CJS therefore has both practical and sociological significance.
Formal social control
The criminal justice system is a major form of formal social control.
Formal social control involves officially organised rules and sanctions used to regulate behaviour.
AQA's 2024 Paper 3 item explicitly described the CJS deciding punishments for people who break the law as a form of formal social control.
The process can be represented as:
law broken → criminal justice response → detection and/or punishment → attempt to regulate future behaviour
This links directly with social order and social control [Social order and social control].
However, sociologists disagree about what this control achieves and whose interests it serves.
The role of the criminal justice system
Crime detection
One role of criminal justice institutions is to detect crime.
AQA's 2025 item specifically identifies crime detection as part of the CJS.
Detection matters because an offence that is never detected may:
remain outside criminal justice processes;
never result in punishment;
remain outside some official statistics.
The basic process is:
offence → detection → formal criminal justice response
This means criminal justice agencies influence not only crime control but also the evidence sociologists use to study crime.
Policing and detection
The 2025 examiner report specifically noted that successful students could make the connection between policing and crime detection.
Police attention can influence which behaviour becomes visible to the criminal justice system.
If policing successfully detects offending:
greater detection → greater possibility of formal intervention
However, policing also creates questions about:
selective enforcement;
bias;
which offences receive attention;
which groups become most visible in crime statistics.
Detection is therefore both a practical crime-control function and a sociological process.
Detection and recorded crime
An important distinction is:
actual offending ≠ detected offending ≠ recorded offending
Not every offence is necessarily detected.
If one type of crime or one social group receives greater police attention, more of that offending may become visible.
This means official statistics can partly reflect:
where criminal justice agencies look
as well as:
where offending occurs
This issue has appeared repeatedly across the unit in ethnicity and crime [Ethnicity and crime], gender and social class.
Bias in detection
AQA's 2025 mark scheme explicitly accepts the argument that biases in policing may mean some crimes go undetected, giving white-collar crime as an example.
This creates an important criticism of the CJS.
If detection is socially uneven:
some crimes receive greater attention → more likely to enter official statistics
while:
other crimes receive less attention → more likely to remain hidden
The resulting official pattern may therefore not represent all offending equally.
Social class and criminal justice detection
AQA's 2023 mark scheme accepts the argument that the criminal justice system may be biased in favour of the middle class, with selective law enforcement making middle-class people less likely to be convicted.
This can be linked with white-collar crime.
The sociological argument is:
different forms of offending receive unequal criminal justice attention → unequal likelihood of detection and conviction
This challenges the assumption that official crime statistics simply record pre-existing criminal behaviour neutrally.
Ethnicity and the criminal justice system
The relationship between ethnicity and criminal justice agencies has been directly assessed by AQA.
The 2021 Paper 3 item stated that people from some minority ethnic groups were more likely to experience outcomes including:
stop and search;
arrest;
conviction;
imprisonment.
It also presented the argument that criminal justice processes may label and criminalise some minority ethnic groups.
Relevant sociological concepts include:
labelling;
stereotyping;
institutional racism;
differential enforcement;
surveillance;
stop and search;
criminalisation;
typifications.
The important point for this lesson is that criminal justice agencies may help produce recorded social patterns as well as respond to offending.
Gender and criminal justice treatment
AQA's 2024 mark scheme accepts the argument that the criminal justice system may treat women more leniently and therefore make them less likely to be convicted.
AQA's earlier mark scheme also recognises a contrasting feminist argument, that criminal justice processes can reinforce patriarchy, for example where women's complaints in rape cases are not taken seriously.
These arguments demonstrate that feminist interpretations of criminal justice are not simply about one universal form of treatment.
They ask how:
gender assumptions;
gender stereotypes;
patriarchal power
may affect criminal justice outcomes.
This links directly with gender and crime [Gender and crime].
Punishment
Punishing offenders
AQA's 2025 item identifies punishment as a central responsibility of the criminal justice system.
Punishment may be intended to:
deter;
incapacitate;
express disapproval;
protect the public;
reinforce values;
contribute to social order.
These purposes are developed fully in [Punishment].
For this lesson, the key issue is whether punishment carried out through the CJS successfully contributes to reduced crime.
Punishment and deterrence
One function identified by AQA is deterrence.
The criminal justice system may attempt to discourage offending by attaching negative consequences to criminal behaviour.
The intended relationship is:
punishment → increased cost of crime → deterrence → reduced future offending
However, the existence of punishment does not guarantee that people are deterred.
AQA's 2024 mark scheme recognises that:
some offenders are not deterred;
punishment may not outweigh the perceived benefits of crime.
Therefore:
intended function ≠ guaranteed outcome
Rehabilitation
Rehabilitation is another major CJS role.
AQA's 2020 mark scheme describes rehabilitation as attempting to reform offenders and gives education and training in prisons as an example.
The process is:
offender enters criminal justice process → rehabilitation → change in behaviour or circumstances → lower likelihood of further offending
The aim is therefore longer-term change rather than simply immediate punishment.
Rehabilitation may fail
The 2025 mark scheme directly identifies ineffective rehabilitation as one reason the CJS may fail to reduce crime.
Its top-band example notes that not all offenders are effectively rehabilitated by prisons, with continued offending demonstrating that rehabilitation does not always succeed.
This is a crucial evaluative distinction:
offender receives rehabilitation ≠ offender necessarily becomes rehabilitated
The existence of a programme tells us its purpose.
Evidence about future offending is needed to assess its effectiveness.
Punishment and rehabilitation should be separated
This distinction became particularly important in the 2025 examination.
The examiner report states that many students treated the phrase "punishment and rehabilitation" as one item hook.
Students who separated them and developed:
one argument about punishment;
one argument about rehabilitation
were more successful.
This is useful beyond that particular question.
Punishment and rehabilitation are related, but they are not interchangeable concepts.
Deterrence
The 2025 examiner report also states that students found the deterrence element difficult to access.
A strong explanation should make the causal chain explicit:
criminal justice sanction → offender anticipates negative consequences → crime appears less worthwhile → offending may be avoided
Evaluation then asks:
Are offenders actually aware of the risk?
Do they believe punishment is likely?
Does the punishment outweigh the expected benefit?
Is the particular offence based on rational calculation?
This is stronger than writing merely:
"The CJS deters crime."
Restitution
AQA's 2020 mark scheme identifies restitution as another function of the CJS.
Punishing offenders may help restore justice and contribute to social solidarity.
This shows that the CJS does not only attempt to influence offenders.
It may also serve a wider social function by responding publicly to wrongdoing.
The focus shifts from:
What happens to the offender?
to:
What does the criminal justice response mean for wider society?
Reinforcing shared values
AQA also recognises that the CJS may reinforce shared values by reminding members of society what behaviour is considered unacceptable.
This provides a functionalist interpretation.
The process is:
crime → criminal justice response → moral boundary reinforced → shared values reaffirmed
The CJS can therefore be understood as an institution contributing to social order.
This develops ideas from functionalism and crime studied earlier in the unit.
Protecting the public
AQA's 2020 mark scheme identifies protection of the public as another criminal justice function.
The example given is imprisonment, which separates offenders from the general public.
The mechanism is:
offender restricted → opportunities to offend in wider society reduced → public protected
This is closely related to incapacitation.
However, restricting an offender does not necessarily remove:
the motivation to offend;
underlying causes;
the possibility of future offending after the restriction ends.
Employment
AQA's 2020 mark scheme also accepts providing employment as a function associated with the criminal justice system, referring to jobs including police, lawyers and social workers.
This is a broader social function rather than a direct mechanism for reducing crime.
It is particularly useful in a short-answer question asking for functions of the CJS.
Do not confuse:
a function of the CJS
with
a reason why the CJS reduces crime.
Employment may be a function without being a direct crime-reduction strategy.
Functionalist interpretations of the criminal justice system
A functionalist interpretation emphasises consensus and social order.
The CJS may contribute to society through:
deterrence;
rehabilitation;
restitution;
reinforcement of shared values;
protection of the public.
AQA's 2020 functions mark scheme supports all of these interpretations.
The general functionalist argument is:
formal social control → conformity and reinforcement of values → social order
The criminal justice system is therefore interpreted as performing functions for society as a whole.
Strengths of a functionalist interpretation
Functionalism helps explain why the CJS does more than simply catch offenders.
It draws attention to:
shared expectations;
public protection;
social solidarity;
rehabilitation;
maintenance of social order.
It also explains why criminal justice responses can have significance for people who are not themselves offenders.
However, conflict and feminist perspectives question the assumption that the system works equally for everyone.
Conflict interpretations of the criminal justice system
Conflict sociologists focus on:
power;
inequality;
selective criminalisation;
whose interests institutions serve.
AQA's 2020 mark scheme explicitly accepts the argument that one function of the CJS may be control of the working class, because working-class people are more likely to be criminalised.
This produces a very different interpretation from functionalism.
Functionalist view
CJS → reinforces shared social order
Conflict view
CJS → may maintain an unequal social order
The debate is therefore not necessarily over whether the CJS produces social control.
It is over whose interests that social control serves.
Selective law enforcement
Selective law enforcement occurs where criminal laws or criminal justice attention are not applied equally across all groups and offences.
AQA recognises selective enforcement repeatedly in relation to:
social class;
ethnicity;
white-collar crime.
This can produce:
unequal enforcement → unequal detection → unequal criminalisation → unequal official crime patterns
Conflict approaches therefore challenge the idea that the CJS acts as a neutral mirror of criminality.
White-collar crime and the CJS
The 2025 mark scheme gives white-collar crime going undetected because of policing biases as an example of why the criminal justice system may not reduce crime.
This is important because it links:
class;
power;
crime detection;
formal social control.
If some forms of offending remain outside effective detection:
no detection → no formal intervention → limited opportunity for punishment or rehabilitation
The ability of the CJS to reduce crime therefore depends partly on the ability to identify it.
Marxist interpretations
AQA's 2025 Paper 3 material directly supports a Marxist critique of crime and criminal justice.
The item for the 30-mark Marxism question states that corporate and white-collar crimes often go unnoticed and unpunished.
This supports the broader conflict argument that:
powerful offenders may be less visible;
working-class offending may receive greater criminal justice attention;
law enforcement may operate selectively.
The CJS can therefore be interpreted as part of the wider structure of class power.
Feminist interpretations
Feminist sociology focuses on gender and patriarchy.
AQA's 2020 mark scheme explicitly recognises the interpretation that the CJS may reinforce patriarchy, with women's complaints in rape cases potentially receiving inadequate recognition.
A feminist interpretation therefore asks:
Are women's experiences taken equally seriously?
Are gender assumptions built into criminal justice processes?
Does the CJS challenge or reproduce patriarchal relations?
This is different from simply asking whether men or women commit more crime.
It concerns how formal agencies respond to gendered behaviour and victimisation.
Chivalry and gendered criminal justice
AQA also recognises the possibility that women may sometimes receive more lenient criminal justice treatment.
The 2024 mark scheme accepts the argument that women may be treated more leniently and therefore be less likely to be convicted.
This demonstrates why gendered CJS treatment should not be reduced to a single claim.
Sociologists may examine:
possible leniency towards female offenders;
patriarchal treatment of female victims;
gender stereotypes influencing formal control.
The key issue is gendered treatment, not a simplistic assumption that the CJS always advantages or disadvantages women in exactly the same way.
Labelling theory and the CJS
Labelling theory shifts attention towards the process through which people become officially categorised as criminal.
Criminal justice agencies are crucial because they help determine who is:
stopped;
detected;
arrested;
convicted;
punished.
The process can be represented as:
social reaction → formal label → criminalisation
This means criminal justice institutions do not simply discover crime.
They can help construct the official social distribution of crime.
Criminalisation
Criminalisation refers to the process through which people or behaviour become officially defined and treated as criminal.
AQA's ethnicity material explicitly recognises the argument that the CJS may label and criminalise some minority ethnic groups.
This has two important consequences.
First
The likelihood of entering official crime statistics may vary between groups.
Second
The criminal label itself may affect future behaviour and identity.
This links the CJS to the wider interactionist idea that social control can have unintended consequences.
The criminal justice system and recorded crime
The role of the CJS can therefore be summarised as both:
Responding to crime
detection;
punishment;
rehabilitation.
Producing official evidence about crime
deciding which behaviour receives formal attention;
detecting some offences but not others;
contributing to arrest and conviction patterns.
This distinction is essential.
An official crime statistic is not simply a measure of behaviour.
It may also reflect the operation of criminal justice agencies.
Does the CJS reduce crime?
AQA's 2025 examination was built around the proposition that the role of the CJS may not always result in reduced crime.
Several explanations are directly supported by AQA.
1. Some crimes go undetected
If criminal justice agencies fail to detect an offence, they cannot:
punish the offender;
rehabilitate the offender;
deter through a formal response to that offence.
The 2025 mark scheme explicitly uses white-collar crime as an example of offending that may go undetected because of bias in policing.
Therefore:
limited detection → limited formal intervention → crime may continue
2. Rehabilitation may be ineffective
If rehabilitation does not change future behaviour:
rehabilitation attempted → offender continues to offend → crime not reduced
AQA explicitly accepts this argument in the 2025 mark scheme.
The evaluation should focus on the gap between:
intention to rehabilitate
and
actual behavioural outcome.
3. Punishment may not deter
Punishments may be intended to discourage offending, but AQA's 2024 material recognises that:
not everyone is deterred;
the perceived benefits of offending may remain greater than its costs.
Therefore:
punishment → no change in cost-benefit decision → continued offending
This limits the crime-reduction effect of the CJS.
4. Punishment may not tackle root causes
The 2025 mark scheme accepts the argument that fines or other punishments may fail because they do not address the root cause of criminality.
For example, punishment may respond to the behaviour while leaving wider structural circumstances unchanged.
The key distinction is:
reaction to offending
versus
change to the conditions associated with offending
This links the CJS with debates in crime prevention [Crime prevention].
5. Punishment may contribute to further deviance
Earlier AQA punishment material recognises that formal punishment can result in:
labelling;
stigma;
deviant careers;
additional criminal learning.
This produces a serious interactionist criticism.
The CJS may intend:
punishment → less crime
but an unintended process could be:
punishment → criminal identity or learning → further crime
Formal control may therefore sometimes amplify rather than reduce deviance.
6. Bias may mean some offenders escape effective control
AQA explicitly recognises bias in criminal justice processes.
If some social groups or forms of offending receive less attention:
unequal enforcement → some offenders less likely to be formally controlled
This means the CJS may fail to reduce crime because its interventions are selective rather than comprehensive.
This criticism is particularly important in Marxist, feminist and interactionist interpretations.
Other agencies involved in crime control
The AQA specification deliberately refers to:
the criminal justice system and other agencies
rather than crime control being the responsibility of criminal justice institutions alone.
AQA's 2022 mark scheme provides the clearest source-supported example of these other agencies through a multi-agency approach.
It states that:
police;
social workers;
teachers;
doctors
may work together to support individuals and reduce their risk of offending.
Multi-agency approaches
A multi-agency approach involves different institutions working together when addressing crime and the problems associated with offending.
The key idea is that criminal behaviour may relate to issues that fall across several areas of social life.
Rather than relying only on formal punishment:
different agencies cooperate → broader understanding of problems → support offered → risk of offending may be reduced
This approach was explicitly accepted by AQA as a crime-prevention strategy in 2022.
Police within a multi-agency approach
Police contribute the formal crime-control dimension.
Within the supplied AQA material, policing is clearly linked to:
detecting crime;
formal social control;
criminal justice responses.
Within a multi-agency approach, however, policing is only one part of the response.
The approach does not assume every crime-related problem can be solved through enforcement alone.
Social workers
AQA explicitly includes social workers among agencies that may cooperate to support individuals and reduce the risk of offending.
The source supports the broader idea that multi-agency working can provide a better understanding of issues faced by individuals and allow support to be offered.
The supplied mark schemes do not provide a more detailed breakdown of the specific professional responsibilities of social workers in crime control.
Teachers
AQA also explicitly includes teachers within multi-agency crime prevention.
Their inclusion demonstrates that crime prevention may involve agencies whose main social role is not conventional law enforcement.
The sociological significance is that:
crime control can involve institutions beyond the police and prisons
when offending is understood as connected with wider social circumstances.
The supplied sources do not provide detailed professional procedures for teachers within multi-agency crime control, so these should not be invented.
Doctors
Doctors are also included in AQA's multi-agency example.
Again, the source-supported point is not a detailed description of medical practice.
It is that crime prevention may involve cooperation between agencies from different areas of social life.
This broadens crime control from:
criminal justice response only
to:
coordinated social intervention
Why multi-agency working may reduce crime
AQA's 2022 mark scheme gives a clear mechanism:
agencies work together → better understanding of issues faced by individuals → support can be offered → reduced risk of offending.
This differs from traditional punitive control.
Punitive model
offence → punishment
Multi-agency model
problems and risk factors identified → support from several agencies → attempt to prevent offending
This places multi-agency working closer to social and community crime prevention.
Multi-agency approaches and social causes
A multi-agency approach is especially compatible with explanations that see crime as connected with wider social circumstances.
If offending is related to several areas of a person's life, cooperation between several agencies may offer a broader response than a single criminal justice institution.
The sociological assumption is:
crime is not always an isolated individual event
It may be connected with:
social circumstances;
interactions with institutions;
wider problems requiring different forms of support.
Criminal justice versus multi-agency control
Criminal justice response | Multi-agency response |
Includes detecting crime | May involve intervention before further offending |
Includes punishment | Focuses more strongly on support |
Includes rehabilitation | Can involve several forms of expertise |
Formal social control is central | Cooperation across institutions is central |
Police and prisons appear directly in AQA material | Police, social workers, teachers and doctors appear in AQA material |
May react after crime occurs | May seek to reduce future risk through coordinated intervention |
These approaches can overlap.
For example, the police can be part of both the CJS and a multi-agency approach.
Crime control is not only policing
One important lesson from AQA's specification wording is that crime control involves other agencies, not simply the CJS.
This matters because crime may be approached through:
formal enforcement;
punishment;
rehabilitation;
social support;
prevention;
coordinated intervention.
The involvement of social workers, teachers and doctors shows that sociological approaches to crime control can extend beyond institutions whose primary role is law enforcement.
Functionalist interpretation of agencies
A functionalist interpretation can view criminal justice and other agencies as institutions contributing to the effective operation of society.
The CJS may:
deter crime;
rehabilitate offenders;
reinforce values;
protect the public.
Other agencies may cooperate to:
understand social problems;
support individuals;
reduce future offending.
The common theme is:
institutions perform functions that contribute to social order
This is consistent with a consensus approach.
Conflict interpretation of agencies
Conflict sociologists challenge the assumption that agencies operate neutrally for society as a whole.
AQA assessment material supports critiques involving:
selective law enforcement;
working-class criminalisation;
white-collar crime going undetected;
unequal treatment by ethnicity.
From this perspective:
formal agencies may contribute to unequal social control
rather than simply enforce universally shared values.
Feminist interpretation of agencies
A feminist approach asks whether the criminal justice system reproduces gender inequalities.
AQA's mark schemes support two types of gendered analysis:
the CJS may sometimes treat female offenders more leniently;
criminal justice processes may reinforce patriarchy in their response to female victims.
The important issue is therefore:
how gender assumptions shape formal social control
rather than assuming one identical effect in every criminal justice situation.
Labelling interpretation of agencies
A labelling approach focuses on the power of agencies to categorise behaviour and people.
Police and other CJS institutions help determine:
who becomes visible;
who is stopped;
who is detected;
who enters official records;
who receives a criminal label.
This may result in:
differential enforcement → differential criminalisation
The CJS therefore contributes to the social construction of official crime patterns.
The CJS and social order
The criminal justice system can be interpreted as helping maintain social order in several ways.
Deterrence
Potential offenders may avoid crime.
Rehabilitation
Offenders may return to society with a lower risk of future offending.
Incapacitation and public protection
Offenders may be prevented from committing some further crimes in wider society.
Reinforcing shared values
Punishment demonstrates which behaviour is unacceptable.
Restitution
Formal responses may help restore a sense of justice.
However, conflict theorists challenge whether this social order reflects consensus or unequal power.
The CJS and social differentiation
The criminal justice system is an especially important application of the AQA core theme of social differentiation, power and stratification.
The key sociological issue is not only:
Does someone commit an offence?
It is also:
How likely is that behaviour to be detected, defined, prosecuted or punished?
These probabilities may be connected with:
social class;
ethnicity;
gender;
the type of offence.
This means criminal justice processes may affect the social distribution of recorded crime.
The criminal justice system and ethnicity
AQA's 2021 Paper 3 makes this particularly clear.
It presented two broad interpretations:
Labelling and criminalisation interpretation
Ethnic differences in recorded crime may result partly from the way some minority ethnic groups are treated by criminal justice agencies.
Realist interpretation
There may also be genuine differences in offending connected with processes such as relative deprivation or social control.
This is an important evaluative model for the whole CJS topic.
You should avoid either extreme:
"Official statistics perfectly reflect actual offending."
or:
"All recorded differences are entirely created by the CJS."
A sociological answer can consider both behaviour and institutional response.
The CJS and social class
The same distinction applies to class.
AQA recognises:
selective enforcement;
working-class criminalisation;
white-collar crime;
unequal conviction patterns.
The official class pattern can therefore potentially reflect:
genuine differences in offending + differences in criminal justice treatment
This is more sociologically developed than assuming the CJS either creates the entire pattern or has no influence on it.
The CJS and gender
Gender also illustrates the interaction of behaviour and formal control.
AQA's 2024 material recognises that women may experience different treatment from the CJS and may therefore be less likely to be convicted.
Formal social control can therefore contribute to the gender pattern found in official statistics.
Again:
recorded offending = behaviour filtered through criminal justice processes
Detecting crime does not necessarily reduce crime
This is one of the most important points from the 2025 paper.
Detection is necessary for many formal responses, but detection alone does not necessarily change the cause of offending.
The chain could be:
crime detected → offender punished → underlying cause remains → further offending
Alternatively:
crime detected → rehabilitation successful → future offending reduced
Detection is therefore the beginning of a formal response, not proof that crime will ultimately decrease.
Punishment does not necessarily reduce crime
Punishment may:
deter;
incapacitate;
express social values.
But it may also:
fail to deter;
contribute to labelling;
leave structural causes unchanged;
create opportunities for criminal learning.
This demonstrates the importance of distinguishing:
the role of the CJS
from
the effectiveness of the CJS.
Rehabilitation does not necessarily reduce crime
Similarly:
rehabilitation is an intended role
while:
successful behavioural change is an outcome
AQA's 2025 mark scheme explicitly rewards evaluation of whether rehabilitation actually reduces crime.
A precise examination answer therefore avoids saying:
"The CJS reduces crime because it rehabilitates offenders."
Instead:
"The CJS attempts to reduce crime through rehabilitation, although this is limited where rehabilitation does not prevent further offending."
Other agencies and the causes of crime
The inclusion of other agencies creates a broader model of crime control.
If crime is connected with wider social problems, punishment alone may be insufficient.
A multi-agency approach attempts to provide:
support + understanding + coordinated intervention
rather than relying exclusively on:
detection + punishment
This gives students a useful way of evaluating criminal justice approaches that focus too narrowly on offending after it has occurred.
Agencies and crime prevention
Multi-agency approaches were accepted by AQA within a question on crime prevention.
This means agencies may act at different stages.
Reactive role
Responding after crime has occurred.
Preventive role
Attempting to reduce the risk of offending before further crime occurs.
The police can be involved in both.
Other agencies may contribute more strongly through coordinated support.
Agencies and surveillance
Surveillance is also connected with the CJS.
The 2025 examiner report notes that students sometimes discussed surveillance but failed to make clear how it related to the criminal justice system.
This is an important examination lesson.
Do not simply write:
"Surveillance stops crime."
For a CJS question, explain:
surveillance or monitoring → police/criminal justice detection → formal response
The institutional link must be explicit.
Agencies and victims
The CJS also operates within a wider social context involving victims of crime [Victims of crime].
The supplied sources for this lesson focus primarily on:
detection;
punishment;
rehabilitation;
social control.
They do not provide a detailed source-supported account of services delivered to victims by individual CJS or non-CJS agencies.
Sociological interpretations compared
Perspective | Interpretation of the CJS and other agencies | Key evaluation question |
Functionalism | Agencies contribute to social order through deterrence, rehabilitation, shared values and protection | Do institutions operate for society as a whole? |
Conflict / Marxism | Formal control may reproduce class inequalities and selectively criminalise | Are powerful and less powerful offenders treated equally? |
Feminism | Criminal justice processes may reflect gendered or patriarchal assumptions | How does gender affect treatment within the system? |
Labelling theory | Agencies help determine who becomes officially criminalised | Does the CJS simply discover crime or partly construct recorded patterns? |
Realist / practical approaches | Formal and multi-agency controls may be needed to reduce real crime | Do the strategies actually reduce offending? |
Multi-agency approach | Crime prevention may require coordinated social support beyond punishment | Does addressing wider issues provide a broader response than formal enforcement alone? |
The strongest evaluation compares these perspectives around specific CJS roles.
Evaluating the criminal justice system
A useful AO3 framework is to ask six questions.
1. Does the CJS detect all forms of crime equally?
AQA explicitly recognises that policing bias may allow offences such as white-collar crime to go undetected.
2. Does punishment deter?
Some people may continue offending despite criminal justice sanctions.
3. Does rehabilitation work?
The CJS may attempt reform without necessarily achieving reduced future offending.
4. Does formal control address causes?
Punishment may respond to behaviour without changing underlying social circumstances.
5. Is the system socially neutral?
Class, ethnic and gender analysis all raise questions about unequal treatment.
6. Could other agencies address issues the CJS cannot?
Multi-agency approaches use support from several institutions rather than relying solely on formal criminal justice control.
These six questions provide a strong structure for evaluation.
Intended and unintended consequences
A particularly useful distinction is between intended and unintended consequences.
Intended consequence | Possible unintended consequence |
Detection of crime | Some groups become disproportionately visible |
Punishment | Labelling and deviant careers |
Deterrence | Offenders may remain undeterred |
Rehabilitation | Reoffending may continue |
Surveillance | More recorded crime because more behaviour is detected |
Formal social control | Unequal criminalisation |
Crime reduction | Underlying causes remain unchanged |
This helps you move beyond simply listing functions.
Effectiveness and fairness are different questions
The CJS can be evaluated on at least two dimensions.
Effectiveness
Does it actually reduce crime?
Fairness or social distribution
Does it treat different groups and offences equally?
A strategy could potentially be effective in one sense but unequal in another.
For example, increased police attention may detect more crime but may also disproportionately target particular groups.
Sociological evaluation therefore needs to consider both.
Functions versus failures
Do not confuse these types of question.
"Outline three functions of the criminal justice system"
You need to state what the CJS does or is intended to do.
Possible AQA-supported answers include:
deterrence;
rehabilitation;
restitution;
reinforcing shared values;
public protection;
class control.
"Analyse why the CJS may not reduce crime"
You need limitations such as:
biased detection;
ineffective rehabilitation;
ineffective deterrence;
failure to address root causes.
The knowledge overlaps, but the question demands are different.
CJS functions are not the same as functions of crime
This distinction caused problems in the 2020 examination.
The examiner report states that many students successfully identified three CJS functions, but a common error was to give a positive function of crime without connecting it to the CJS.
For example, students referred to a warning-device or safety-valve function without linking it to a criminal justice institution or process.
Remember:
Function of crime: what crime itself may do for society.
Function of CJS: what criminal justice institutions or processes do.
These are not interchangeable.
Using the 2025 Item A effectively
The 2025 item provided several potential hooks:
detect crime;
punish offenders;
rehabilitate offenders;
the implication of deterrence through criminal justice responses.
The examiner report found that students often failed to separate these clearly.
A strong approach would be:
Point 1: detection
Policing bias may mean some forms of crime remain undetected, limiting the CJS response.
Point 2: rehabilitation
Some offenders may continue offending despite attempts to rehabilitate them.
Or:
Point 1: punishment
Punishment may fail to address causes or deter.
Point 2: rehabilitation
Attempts to reform offenders may be unsuccessful.
The two points need separate causal explanations.
Linking theory to agencies
A strong extended answer can follow this structure:
Functionalist claim
The CJS deters, rehabilitates and reinforces shared values.
Evaluation through effectiveness
Not every offender is deterred or rehabilitated.
Conflict evaluation
Selective enforcement may mean some classes or offences receive less formal control.
Labelling evaluation
Formal intervention may contribute to criminal identities.
Feminist evaluation
Gender assumptions may influence how offenders or victims are treated.
Multi-agency alternative
Crime prevention may involve support from agencies outside traditional punitive institutions.
This creates genuine sociological evaluation.
Named sociologists
The 2025 CJS mark scheme identifies possible sources including:
Chaiken et al;
Clarke;
Durkheim;
Foucault;
Garland;
Graef;
Matthews;
Rusche and Kirchheimer;
Tonry and Farrington.
The mark scheme lists these as potentially relevant sources but does not provide their detailed arguments.
For source-grounded revision, prioritise the concepts and arguments that AQA actually develops in its mark schemes:
detection;
punishment;
rehabilitation;
deterrence;
selective enforcement;
criminalisation;
multi-agency working.
Building an evaluative argument
Suppose the question asks:
"Evaluate the view that the criminal justice system is effective in controlling crime."
A strong structure could be:
Detection: formal agencies can identify crime and enable intervention.
Evaluate: policing bias may leave some offences such as white-collar crime undetected.
Punishment and deterrence: sanctions may discourage future offending.
Evaluate: some offenders remain undeterred and punishments may not tackle root causes.
Rehabilitation: the CJS may try to reform offenders.
Evaluate: rehabilitation does not always prevent further offending.
Functionalism: formal control can reinforce shared values and social order.
Conflict evaluation: selective enforcement may criminalise working-class or minority groups disproportionately.
Labelling: formal intervention may contribute to further deviance.
Other agencies: multi-agency working may provide a broader preventive approach by offering coordinated support.
Judgement: the effectiveness and sociological significance of the CJS depend on detection, the success of intervention and the social distribution of formal control.
This keeps the essay focused on agencies and their roles, rather than drifting into general theories of crime.
Key Words 🔑
Key word | Student-friendly definition | How it may be used in an exam |
Criminal justice system (CJS) | Institutions and processes involved in formally detecting and responding to crime. | Use as the central concept when discussing detection, punishment and rehabilitation. |
Formal social control | Officially organised regulation of behaviour through rules, institutions and sanctions. | Use to explain the wider social role of the CJS. |
Detection | The process through which offending is identified by criminal justice agencies. | Use when explaining the police role and why some crimes enter official records. |
Punishment | A formal response imposed on people whose behaviour has been defined as criminal. | Use when examining deterrence, control and public protection. |
Rehabilitation | Attempts to reform offenders so they are less likely to offend again. | Use when evaluating whether the CJS successfully reduces future crime. |
Deterrence | Discouraging offending through the threat or experience of negative consequences. | Use when explaining one intended crime-control function of the CJS. |
Selective law enforcement | Unequal enforcement of criminal law across groups or types of crime. | Use when evaluating class, ethnic or other inequalities in the CJS. |
Criminalisation | The process through which behaviour or people become officially defined and treated as criminal. | Use in labelling and conflict interpretations of criminal justice agencies. |
Multi-agency approach | Different institutions working together to address offending and associated problems. | Link to police, social workers, teachers and doctors in AQA's crime-prevention material. |
Restitution | A function of criminal justice responses concerned with restoring justice and social relationships. | Use as an AQA-supported function of the CJS. |
Hints from the Examiner Reports 💡
This lesson has particularly strong examiner guidance because the criminal justice system was directly assessed in both 2020 and 2025.
Examiner hint: Separate the hooks in an item. In 2025, students often treated "punishment and rehabilitation" as one point. Students who developed punishment and rehabilitation separately were more successful.
Examiner hint: Make the link to the criminal justice system explicit. Some students discussed surveillance in 2025 but did not explain how surveillance connected with a criminal justice institution or process.
Examiner hint: Policing and detection can provide strong development. The 2025 report states that students who connected policing with crime detection were able to develop arguments about biased policing by gender, social class or ethnicity.
Examiner hint: Do not drift into a generic explanation of crime. In 2025, some students discussed poverty or root causes without linking their point clearly to the role of the CJS.
Examiner hint: Do not confuse functions of crime with functions of the criminal justice system. The 2020 report found that students sometimes used functionalist ideas such as the warning-device or safety-valve function without connecting them to a CJS institution or process.
Examiner hint: AO3 continues to be more challenging than AO1. The 2025 report notes that students were generally strongest on knowledge but found evaluation more difficult. Evaluation should therefore assess how far the agency actually achieves the function being discussed, rather than simply naming a criticism.
Common Mistakes ⚠️
Mistake: Treating the criminal justice system as simply another word for the police
Why this is incorrect: AQA describes the CJS more broadly as institutions involved in detecting crime, punishing offenders and rehabilitating offenders.
How to improve: Use policing when discussing detection, but remember that punishment and rehabilitation are also central CJS roles.
Mistake: Saying punishment and rehabilitation are the same thing
Why this is incorrect: The 2025 examiner report specifically warns that students often merged these two hooks.
How to improve: Remember:
punishment → formal sanction
rehabilitation → attempt to reform
They may occur together but represent different processes.
Mistake: Naming a function of crime when the question asks for a CJS function
Why this is incorrect: AQA identified this exact problem in 2020.
How to improve: Always connect the function to an institution or process of the criminal justice system.
For example:
shared values reinforced because punishment formally communicates that particular behaviour is unacceptable.
Mistake: Assuming detection automatically reduces crime
Why this is incorrect: Detection allows a formal response but does not prove that punishment or rehabilitation will successfully prevent future offending.
How to improve: Explain the full chain and evaluate each stage.
Mistake: Assuming the CJS detects all crimes equally
Why this is incorrect: AQA's 2025 mark scheme explicitly accepts that policing biases may result in some crimes, including white-collar crime, remaining undetected.
How to improve: Evaluate detection using selective law enforcement and the visibility of different offences.
Mistake: Assuming rehabilitation always works
Why this is incorrect: AQA's 2025 mark scheme explicitly recognises ineffective rehabilitation as a reason the CJS may fail to reduce crime.
How to improve: Distinguish the aim to rehabilitate from evidence of actual reduced future offending.
Mistake: Discussing poverty without linking it to the CJS
Why this is incorrect: The 2025 examiner report found that some students drifted into general root-cause arguments rather than analysing a criminal justice role.
How to improve: Make the institutional link explicit:
punishment may fail because it reacts to offending without addressing the underlying cause.
Mistake: Assuming formal control is socially neutral
Why this is incorrect: AQA materials support class, ethnic and gender critiques of criminal justice processes.
How to improve: Consider who is detected, labelled, convicted or punished, as well as whether crime is reduced.
Mistake: Ignoring other agencies
Why this is incorrect: The specification explicitly requires the criminal justice system and other agencies.
How to improve: Revise AQA's multi-agency example involving police, social workers, teachers and doctors working together to support individuals and reduce offending risk.
Mistake: Inventing detailed professional roles not provided by the source
Why this is incorrect: The AQA specification does not provide a detailed institutional handbook for every criminal justice or multi-agency profession.
How to improve: Stay focused on the roles the assessment material actually establishes: detection, punishment, rehabilitation and coordinated support.
Exam-Style Questions ✍️
Question 1
Define formal social control. [1 mark]
Question 2
Explain one way in which the criminal justice system may attempt to rehabilitate offenders. [2 marks]
Question 3
Outline two functions of the criminal justice system. [4 marks]
Question 4
Outline three reasons why the criminal justice system may not always reduce crime. [6 marks]
Question 5
Explain two ways in which the operation of criminal justice agencies may affect recorded patterns of crime. [4 marks]
Question 6
Read Item A and answer the question that follows.
Item A
Criminal justice institutions attempt to detect offending and then respond through formal controls. However, some forms of crime may be more visible to agencies than others, and not every offender responds to punishment in the same way.
Applying material from Item A, analyse two reasons why criminal justice processes may not always reduce crime. [10 marks]
Question 7
Read Item B and answer the question that follows.
Item B
Crime control does not always involve one institution acting alone. Police may work alongside professionals in areas such as education, health and social support. Cooperation may enable agencies to understand a wider range of problems associated with offending.
Applying material from Item B, analyse two ways in which a multi-agency approach may contribute to crime control. [10 marks]
Question 8
Read Item C and answer the question that follows.
Item C
The criminal justice system detects crime, punishes offenders and attempts to rehabilitate them. Consensus sociologists may see these institutions as helping to maintain social order. However, other sociologists argue that detection and punishment are socially unequal and may contribute to the criminalisation of particular groups. Crime control can also involve agencies outside the traditional criminal justice system.
Applying material from Item C and your knowledge, evaluate sociological interpretations of the role of the criminal justice system and other agencies in controlling crime. [30 marks]
Answers and mark scheme
Question 1
1 mark for an accurate definition referring to official or institutionally organised regulation of behaviour.
Example answer: Formal social control is the official regulation of behaviour through institutions, rules and sanctions.
Question 2
Award up to 2 marks.
Example answer: The criminal justice system may attempt to rehabilitate offenders through education or training in prison. This is intended to reform offenders so that they are less likely to commit further crime.
One mark identifies an appropriate process and one further mark develops the rehabilitation link.
Question 3
Award 2 marks for each of two clearly outlined functions.
Possible answers include:
Deterrence: Punishment may discourage potential offenders by increasing the negative consequences associated with crime.
Rehabilitation: Prisons may provide education and training intended to reform offenders.
Restitution: Formal punishment may help restore justice and contribute to social solidarity.
Reinforcing shared values: Criminal justice responses demonstrate which behaviour society regards as unacceptable.
Protection of the public: Restricting offenders can reduce their opportunities to offend against the wider public.
Class control: A conflict interpretation may argue that the CJS contributes to working-class criminalisation.
One mark identifies the function and one further mark develops it.
Question 4
Award 2 marks for each of three genuinely different reasons.
Possible answers include:
Crime may remain undetected: biased or selective policing may mean some offences, such as white-collar crime, receive insufficient formal attention.
Rehabilitation may fail: offenders may continue offending despite attempts to reform them.
Punishment may not deter: some offenders may judge the benefits of crime to outweigh its costs.
Root causes may remain: sanctions may react to offending without changing the social circumstances associated with crime.
Labelling: formal criminalisation may produce stigma and contribute to further deviance.
Bias: some groups or forms of offending may be more or less likely to receive formal criminal justice attention.
One mark identifies the reason. The second explains why it limits crime reduction.
Question 5
Award 2 marks for each of two developed ways.
Possible answers include:
Selective detection: If one group or type of offence receives more policing, more of its offending may be detected and recorded, increasing its representation in official statistics.
Under-detection: If offences such as some white-collar crimes receive less criminal justice attention, they may be underrepresented in official crime statistics.
Criminalisation: Differential enforcement can make particular groups more likely to be formally labelled and convicted, affecting the social distribution shown in recorded crime.
Question 6
Students should develop two distinct hooks from Item A.
Hook 1: unequal visibility and detection
The CJS can only formally respond to offences it detects. Selective policing may make some offending highly visible while other offences, such as some white-collar crime, remain undetected. This limits punishment or rehabilitation of those offenders.
Hook 2: response to punishment
The CJS may punish offenders in order to deter them. However, not every offender is deterred, particularly where the expected benefit of offending is judged to outweigh the possible sanction.
Students could instead develop ineffective rehabilitation as the second hook.
8 to 10 marks: Good knowledge and understanding of two reasons, two developed applications of Item A and clear analysis of why CJS processes may fail to produce reduced crime.
4 to 7 marks: Reasonable knowledge and some successful item application, although one explanation may be more developed.
1 to 3 marks: Limited knowledge, little effective item application or drift into general explanations of crime without connecting them to the CJS.
0 marks:No relevant material.
Question 7
Students should remain tightly within the source-supported multi-agency material.
Hook 1: agencies from different areas
Police, social workers, teachers and doctors may work together rather than treating offending as an issue for law enforcement alone.
This may provide a broader understanding of the circumstances associated with offending.
Hook 2: coordinated support
Once problems are better understood, support can be offered to individuals in an attempt to reduce their risk of offending.
The process can therefore be:
cooperation → better understanding → support → reduced offending risk
8 to 10 marks: Good knowledge and understanding of two aspects of multi-agency working, developed application of Item B and clear analysis of how coordinated intervention may contribute to crime control.
4 to 7 marks: Reasonable knowledge with some successful item application and analysis.
1 to 3 marks: Limited knowledge or a general list of professions without explaining multi-agency crime control.
0 marks: No relevant material.
Question 8
This question requires knowledge and understanding, application, analysis and evaluation.
Indicative content may include:
Roles of the criminal justice system
crime detection;
punishment;
rehabilitation;
deterrence;
restitution;
protection of the public;
reinforcing shared values.
Students may explain how each role is intended to contribute to social control or crime reduction.
Functionalist interpretations
consensus;
formal social control;
deterrence;
rehabilitation;
shared values;
restitution;
social solidarity;
social order.
Students may argue that criminal justice institutions perform necessary social functions.
Evaluation of effectiveness
crime going undetected;
policing bias;
white-collar crime;
unsuccessful rehabilitation;
ineffective deterrence;
punishment failing to tackle root causes.
Students should distinguish the intended role of an agency from evidence of its success.
Conflict and Marxist approaches
class control;
selective enforcement;
working-class criminalisation;
white-collar and corporate crimes receiving less attention;
unequal power.
These arguments may challenge functionalist assumptions of neutrality and consensus.
Labelling theory
stereotyping;
differential enforcement;
criminalisation;
official labels;
social construction of crime statistics.
Students may argue that agencies help produce official crime patterns rather than merely discovering pre-existing criminality.
Ethnicity
stop and search;
arrest;
conviction;
imprisonment;
institutional racism;
differential enforcement.
Students may use ethnicity to demonstrate possible unequal operation of formal control.
Gender and feminism
gendered criminal justice treatment;
possible leniency towards female offenders;
feminist arguments concerning patriarchal treatment within criminal justice processes.
Students should avoid assuming all gendered effects are identical.
Other agencies
multi-agency working;
police;
social workers;
teachers;
doctors;
better understanding of individuals' problems;
coordinated support;
reducing the risk of offending.
Students may use this to argue that formal punishment is not the only possible response to crime.
25 to 30 marks: Sound, conceptually detailed knowledge of a range of sociological interpretations of criminal justice and other agencies. Item material is applied accurately. Analysis and evaluation explicitly consider crime detection, punishment, rehabilitation, inequality, criminalisation and multi-agency approaches. A reasoned judgement is reached.
19 to 24 marks: Accurate and reasonably broad or deep knowledge. Application is largely focused, and there is some explicit evaluation of agency effectiveness or inequality, although parts may be incomplete.
13 to 18 marks: Largely accurate but narrower knowledge. Application may be limited and evaluation may rely mainly on placing functionalist, Marxist or interactionist approaches alongside each other without developing their significance.
7 to 12 marks: Limited and undeveloped knowledge, with weak application and little evaluation. There may be drift into general crime prevention or theories of crime without sustained focus on agencies.
1 to 6 marks: Very limited relevant material or a general discussion of crime and punishment with little understanding of the CJS and other agencies.
0 marks: No relevant material.
A strong conclusion should recognise that criminal justice agencies perform several important roles but that role and effectiveness are not the same thing. Detection can enable intervention, punishment may deter and rehabilitation may change behaviour, but AQA evidence also highlights selective detection, unsuccessful rehabilitation and unequal criminalisation. Functionalists therefore provide a useful account of the CJS as a source of social order, while conflict, feminist and labelling perspectives reveal how formal control may operate unevenly. The inclusion of multi-agency approaches further demonstrates that controlling crime can involve coordinated social support as well as detection and punishment.
