Prison Education Works: The Evidence Politicians Keep Ignoring

One of the most frustrating aspects of my work with Inside Out Justice has been encountering an enormous gap between what the evidence shows works in prisons and what policy actually does. We have decades of rigorous research demonstrating that education and training in prisons dramatically reduces reoffending rates. We have data from the Coates Review, from the RAND Corporation’s meta-analysis of prison programmes, from the Open University’s work in prisons, from the Prisoners’ Education Trust’s longitudinal studies. The evidence is consistent, robust, and unambiguous: prisoners who engage in education whilst imprisoned are far less likely to reoffend after release. Yet despite this evidence, prisons continue to operate with minimal educational provision, government funding for prison education has been cut repeatedly, and educational programmes remain a luxury rather than a core part of what prisons do. This post examines what the evidence actually shows, why policy hasn’t caught up with evidence, and what genuine prison reform would look like if we actually cared about reducing crime rather than just managing criminals.

The Basic Evidence: What Research Shows About Prison Education

Let’s start with the most recent comprehensive review of the evidence. The RAND Corporation’s meta-analysis of 57 studies examining the impact of prison education programmes found that participation in these programmes reduces the probability of reoffending by 43%. This is an enormous effect. To put it in perspective, 43% reduction is one of the largest impacts of any intervention we know how to deliver in criminal justice. Prison education works better than most drugs, better than most counselling interventions, better than most behavioural programmes. The Coates Review of 2016, commissioned by the UK government, examined prison education specifically in the UK context and reached similar conclusions: education and training in prisons significantly improves outcomes and reduces reoffending rates. Yet despite these findings from a government-commissioned review, funding for prison education has continued to decline.

The mechanisms by which education reduces reoffending are reasonably well-understood. First, education improves employment prospects after release. Prisoners with qualifications and skills have better job options, which means they’re less likely to return to crime out of economic desperation. Second, education provides purpose, structure, and engagement whilst in prison, which improves mental health and reduces the desperation and hopelessness that drive reoffending. Third, education builds self-efficacy and confidence—many prisoners come from backgrounds where education has been a site of failure and shame, and successfully completing a qualification reverses those narratives. Fourth, education provides social connection and community within the prison, which reduces isolation and the antisocial behaviour patterns that characterise some prison cultures. These aren’t just theories—they’re observed patterns in the data across multiple studies.

The Open University in Prisons: A Model That Works

One of the most successful education programmes operating in UK prisons is the Open University in Prisons. This programme allows prisoners to study Open University courses whilst imprisoned and earn degrees. The data on outcomes is remarkable. Prisoners who study with the Open University whilst in prison have reoffending rates of around 10%, compared to the national average reoffending rate of approximately 40% within two years of release. This is not a small effect. This is a transformative difference. A prisoner who completes a degree through the Open University whilst imprisoned is four times less likely to reoffend than a prisoner who doesn’t participate in education. That’s a dramatic reduction that would make any criminal justice intervention famous if it were a pharmaceutical drug or a behavioural therapy.

Yet the Open University in Prisons operates with minimal government funding, largely reliant on charitable support and the work of committed academics and volunteers. The programme reaches only a small fraction of the prisoner population—at any given time, only a few hundred prisoners out of a population of over 80,000 are studying. This isn’t because people don’t want to participate. Waiting lists for Open University courses in prisons are long. It’s because there’s insufficient funding to expand the programme to meet demand. If we truly cared about reducing reoffending and crime, we would expand this programme to reach tens of thousands of prisoners. The return on investment is enormous—every pound spent on prison education saves money in terms of reduced imprisonment, reduced crime, and increased tax revenue from formerly imprisoned people who successfully integrate into employment. Yet policy continues to be driven by short-term thinking rather than evidence-based cost-benefit analysis.

The Prisoners’ Education Trust and Longitudinal Data

The Prisoners’ Education Trust has conducted longitudinal research tracking prisoners who engaged in education whilst imprisoned and following their outcomes after release. This research provides some of the most compelling evidence for prison education’s effectiveness. Prisoners who engaged with PET programmes showed significantly better employment outcomes after release, higher earnings, greater life satisfaction, and lower reoffending rates. Importantly, the research also found that prisoners who engaged in education reported better mental health whilst imprisoned and better psychological adjustment after release. This suggests that the benefits of prison education extend beyond employment and reoffending reduction to general wellbeing and social integration.

What’s striking about PET’s research is that it controls for selection effects—that is, it accounts for the possibility that more motivated prisoners self-select into education programmes. Even when you account for this, the effect of education on reducing reoffending remains substantial and statistically significant. This means we’re not just seeing a selection effect where more motivated prisoners naturally reoffend less. We’re seeing an actual causal effect of education on subsequent outcomes. The research also found that the type of education matters less than the fact of engagement—whether someone did a basic numeracy course, a GCSEs qualification, or a degree-level course, there were benefits relative to no educational engagement.

Comparing UK Approaches with Nordic Models

If we want to understand what genuinely evidence-based prison policy looks like, we should examine the Nordic countries, particularly Norway and Sweden. These countries have built prison systems explicitly around rehabilitation and education, rather than primarily around punishment and containment. Norwegian prisons offer comprehensive educational programmes, vocational training, and psychological support. The results are striking: Norway’s reoffending rate is approximately 20%, compared to the UK’s 40%. Sweden’s reoffending rate is similar. These aren’t marginal differences. These are enormous differences that translate into dramatically different crime rates, different imprisonment costs, and different social outcomes.

The question, of course, is whether these differences are due to the prison systems or due to broader social differences between Nordic countries and the UK. This is a legitimate question, and the honest answer is that multiple factors contribute. Nordic countries have stronger social safety nets, lower income inequality, better public health systems, and different cultural attitudes toward punishment. These broader contextual factors absolutely matter for crime rates and reoffending. But the prison system research in Nordic countries still suggests that an educational approach reduces reoffending relative to a purely punitive approach. When researchers have compared reoffending rates for similar prisoners in Nordic prisons versus more punitive prisons in other countries, the educational approach consistently produces better outcomes. This suggests that even in the UK context, where we can’t implement the entire Nordic welfare state, improving prison education would improve outcomes.

The Cost-Benefit Analysis That Should Drive Policy

Let’s do some basic cost accounting. The average cost of imprisoning someone in a UK prison is approximately £35,000 per year. The average sentence length is around 18 months for those serving determinate sentences, meaning the average imprisonment cost per person is roughly £52,500. If education reduces reoffending by 43%, and the average person who reoffends spends another 18 months imprisoned, then the cost savings from preventing reoffending is roughly £22,500 per person. The cost of providing comprehensive educational programmes to prisoners is substantially less than this. A degree-level education programme through the Open University costs roughly £3,000 to £4,000 per student. Even if we provided this to a significant fraction of the prison population, the cost per life-year of reoffending prevented would be extraordinarily favourable compared to other criminal justice interventions.

This isn’t even accounting for other benefits: the reduction in crime that prevented reoffending creates, the improvement in employment and earnings for formerly imprisoned people, the taxes they pay, the reduction in social support they require. One study estimated that every pound spent on prison education returns approximately £2.50 to society in reduced imprisonment costs, increased tax revenue, and reduced crime. This is an enormous return on investment. Yet prison education spending has been cut repeatedly over the past decade, from approximately £100 million annually a decade ago to less than half that today. This isn’t evidence-based policy. It’s the opposite. It’s policy driven by budget constraints and a failure to properly account for the economic benefits of education.

Why Doesn’t Policy Follow the Evidence?

Given that the evidence for prison education is so strong and the cost-benefit case is so compelling, why hasn’t policy changed? There are several explanations. First, there’s a time horizon problem. The benefits of prison education accrue over years or decades—it takes time for someone to progress through a sentence, be released, find employment, and not reoffend. Political systems operate on election cycles of 4-5 years. A politician who funds prison education won’t see the benefits within their term in office. If they want to claim credit for their policies, they need to see results quickly. Prevention and rehabilitation are poor matches for this political incentive structure, whereas incapacitation and containment produce more immediate, visible results.

Second, there’s an identity and narrative problem. The dominant narrative about criminal justice in the UK is punishment and containment. Criminals are bad people who need to be locked away. This narrative is politically powerful because it appeals to legitimate concerns about public safety and justice for victims. Rehabilitation and education suggest that criminals can change, which contradicts this narrative and makes some people uncomfortable. There’s been a long culture war in criminal justice between punitive and rehabilitative approaches, and the punitive approach has generally won in public discourse, even though the evidence favours rehabilitation. Changing policy requires changing narratives, and that’s a slower process than publishing research papers.

Third, there’s a budget constraint problem. Prisons in the UK are chronically underfunded. The prison system has been squeezed by austerity, and funding has been allocated primarily to basic operations and containment. Educational provision requires resources—books, computers, teachers, facilitators. When budgets are tight, education is a natural place to cut because it doesn’t directly contribute to the core mission of containing prisoners. However, this short-term budgeting approach creates long-term costs through higher reoffending rates and the cycle of people returning to prison multiple times. It’s classic false economy—saving money today by cutting education, then spending money tomorrow managing the consequences of poor rehabilitation.

The Inside Out Justice Perspective on Prison Reform

Working with Inside Out Justice has crystallised for me how fundamental prison education is to any serious vision of prison reform. We believe that prisons should be about rehabilitation and preparing people for successful reintegration, not just about punishment and containment. Education is central to that vision. It’s the mechanism through which people develop the skills, credentials, and psychological resources to succeed after prison. It’s the foundation upon which other reforms should build—better mental health services, better vocational training, better support for reintegration. But without education, these other services can only accomplish so much.

Inside Out Justice’s advocacy has focused on making a practical case for prison education: not just that it’s morally right (though it is), but that it works better than the alternative of no education. We’ve worked with researchers, with the Prisoners’ Education Trust, with the Open University, and with other organisations to disseminate evidence and challenge the assumption that prisons are purely about punishment. We’ve highlighted success stories—prisoners who’ve completed qualifications whilst inside and gone on to successful lives outside, whose reoffending was prevented through education. We’ve testified before parliamentary committees about the evidence. We’ve worked with prison governors who understand that education improves behaviour and outcomes in their own facilities. The work is slow, but there’s genuine momentum building.

The Quality and Accessibility Problem

Beyond the funding problem, there’s also a quality and accessibility problem with prison education as it currently operates. Prison libraries have limited resources. Teachers in prison education programmes are often volunteers or low-paid staff, and recruitment is difficult. Prisoners have limited access to computers and digital resources, which is increasingly important for modern education. Assessment and certification can be inconsistent across prisons. Many prisons do offer some education, but the quality is highly variable. A prisoner’s access to good education shouldn’t depend on which prison they’re held in, yet currently it does. Standardising and improving quality across the prison education system would require sustained investment and political commitment.

Additionally, there’s the problem of access for specific populations. Prisoners with literacy difficulties have particular barriers to education. Female prisoners often have different educational needs than male prisoners. Older prisoners may have been out of education for decades and need different support. Prisoners with learning disabilities require adapted approaches. A comprehensive education system would need to account for this diversity and provide appropriate support and challenge for people at different starting points. Most current prison education systems do some of this work, but under-resourced and fragmented.

Vocational Training and Employment Pathways

Beyond academic education, vocational training is also crucial for reducing reoffending. Many prisoners have minimal work experience and need to develop practical skills that employers value. Prison should offer training in trades—plumbing, electrical work, carpentry, construction—and in service industries and other sectors where jobs are available. The problem is that this training is only valuable if it leads to actual employment after release. This requires coordination with employers outside prison, support for prisoner entry into employment, and systems for verifying and recognising the qualifications prisoners obtain. Some prisons do this work well, but again, it’s inconsistent and under-resourced.

What would really move the needle is if the government committed to subsidising employment for formerly imprisoned people, or to creating job placement services specifically for people leaving prison. The cost would be modest compared to the cost of reimprisonment. If someone leaving prison had guaranteed access to a job coach who helped them find work and navigate employment, many would be able to establish themselves in the workforce before the usual temptations to reoffend became overwhelming. This isn’t charity—it’s economic efficiency. We’d be spending money to prevent crime, rather than spending money to manage crime after it occurs.

The Role of Education in Prison Culture and Behaviour

Beyond outcomes after release, education matters for what happens inside prisons. Prisons where education and programmes are robust tend to have better behaviour and fewer disciplinary incidents. This is because education provides purpose, structure, and engagement. Prisoners engaged in meaningful education are less likely to be involved in drugs, violence, or other antisocial behaviour. From a prison management perspective, education is a legitimate tool for improving safety and reducing the burden on security staff. Yet this benefit is rarely invoked in discussions of prison funding. Prison governors will attest that their best-managed facilities are those with the most robust education and programming, yet this evidence doesn’t seem to translate into sustained funding.

There’s also something deeply human about education that speaks to prisoners’ sense of dignity and worth. Many prisoners come from backgrounds where education was a site of shame and failure—they were labelled as failures, excluded from school, told they weren’t capable of academic work. Being given the opportunity to succeed educationally, to earn a qualification, to be recognised as having grown and developed, can be transformative. It’s not just about the qualification itself—it’s about the message that you’re capable of growth and change, that society hasn’t written you off as irredeemable. This psychological dimension of education is harder to measure in cost-benefit terms, but it’s real and important.

The Victims’ Perspective and Crime Reduction

Some argue that focusing on prisoner rehabilitation is disrespectful to victims of crime. But consider the actual impact: if education reduces reoffending by 40%, it prevents crime. It prevents people from becoming victims of crimes by the same person again. The best way to respect victims of crime is to prevent future crime. An approach focused on education and rehabilitation does this more effectively than an approach focused purely on punishment and containment. We can care about both punishment for the crime that occurred and prevention of future crime. But if these goals conflict, evidence suggests we should prioritise prevention. Victims’ organisations increasingly recognise this and support rehabilitation approaches because they understand that rehabilitation prevents future victims.

This doesn’t mean there should be no punishment. It means that punishment shouldn’t be the only purpose of prison. Prison should be about multiple purposes: accountability, rehabilitation, protection of public safety, and reintegration preparation. Education contributes to the latter three purposes—it reduces future crime by building human capital and psychological resources, it protects public safety, and it prepares people for reintegration. A system designed around all four purposes simultaneously would look very different from the current UK prison system, which often treats punishment and rehabilitation as competing rather than complementary.

Policy Recommendations for Prison Education Reform

What would genuine prison education reform look like? First, funding needs to increase substantially. We should commit to spending at least £200 million annually on prison education and training programmes. This would allow every prisoner to have access to meaningful education, whether academic or vocational. Second, the Open University in Prisons programme should be expanded significantly so that anyone motivated to pursue a degree could do so, not just a small fraction of the prison population. Third, prisons should develop partnerships with employers so that vocational training leads to actual job placement after release. Fourth, there should be specialised education programmes for specific needs—literacy support, ESOL for foreign nationals, learning disability support.

Fifth, the government should commit to employment support for people leaving prison, so that education credentials lead to actual jobs. Sixth, prisons should measure and be held accountable for educational outcomes and for the subsequent employment and reoffending rates of people who participated in education programmes. This would create incentives for prisons to take education seriously and to continually improve quality. Seventh, prison education should not be just an add-on programme but should be integrated into the core mission and culture of prisons. Governors should be evaluated partly on their success in educational provision and reoffending reduction, not just on security and order. Eighth, the quality and consistency of prison education should be standardised across all prisons, so that location doesn’t determine access to good education.

The Broader Conversation About Crime and Punishment

What strikes me about the prison education issue is that it reveals something fundamental about how UK policy is made. We have evidence. We have research that’s been replicated multiple times across different contexts. We have cost-benefit analyses showing that education is an economically efficient intervention. We have success stories from prisons and from people who’ve gone through education programmes. Yet policy hasn’t changed significantly. This suggests that policy isn’t driven by evidence—it’s driven by other factors. Ideology about punishment, political narratives, budget constraints, and institutional inertia all play significant roles. Changing policy requires not just better evidence (we already have that) but changing the conversation about what prisons are for and what we value as a society.

The fundamental question is whether we see imprisoned people as humans capable of growth and change, or as permanently damaged people who need to be managed. The evidence overwhelmingly supports the former. Prisoners are not fundamentally different from non-prisoners. They’re people who made serious mistakes or were driven by desperation or circumstance into criminal activity. Many of them are capable of significant change if given the opportunity and support. Education provides that opportunity and support. The question is whether we’re willing to invest in it.

My Personal Commitment to This Cause

My work with Inside Out Justice comes from a genuine belief that prisons can be engines of rehabilitation rather than just engines of warehousing and punishment. I’ve seen how education transforms people’s sense of possibility and agency. I’ve met formerly imprisoned people who credit education programmes with changing their trajectory after release. I’ve worked with prison governors who are genuinely committed to rehabilitation and who can point to the data showing that education improves outcomes. What keeps me engaged in this work is the knowledge that we actually know what works—the evidence is clear—and the fact that we’re not doing it. That gap between evidence and practice is maddening and motivating in equal measure.

My commitment is to keep advocating for prison education, to keep disseminating the evidence, to keep arguing for the economic and moral case for reform. I want to help create a political and cultural environment where investment in prison education becomes obvious rather than controversial. I want to see expansion of programmes like the Open University in Prisons until they’re available to anyone who wants to engage. I want prisoners to have access to the same quality of education that people outside prison can access. And I want to see reoffending rates drop because people are genuinely rehabilitated rather than just contained. That’s a vision of a better criminal justice system, and it’s a vision based on evidence about what actually works.

The Call to Action

If you believe in evidence-based policy, if you believe in rehabilitation and second chances, if you believe that preventing crime is better than managing crime after it occurs, then prison education should be something you care about. You can support organisations like the Prisoners’ Education Trust, which do direct work in this space. You can write to your MP about prison education funding. You can engage in conversations that normalise the idea that prisoners are capable of growth and change. You can support candidates and policies that prioritise rehabilitation. The evidence is clear that prison education works. The only question is whether we’re willing to do it.
