Increase permanent exclusions and double Pupil Referral Units

Reform UK · what the evidence says

An independent, source-checked look at Reform UK’s policy “Increase permanent exclusions and double Pupil Referral Units” — what it would actually do across the things that affect your life. Every claim below quotes the source behind it. How this works.

Crime, justice & national security — Mixed picture

moderate · moderate confidence

Removing violent pupils from mainstream schools would make those schools safer in the short term, but strong evidence links school exclusion to later criminal activity, which risks worsening community safety over time. Whether expanded PRUs can break that link is uncertain given existing evidence of poor PRU outcomes and staffing constraints.

The evidence

Biggest unknown: Whether doubling PRUs and improving their quality can break the well-evidenced link between exclusion and criminal justice involvement, or whether capacity and staffing constraints leave excluded pupils on a school-to-crime pipeline.

Our reading: This policy produces two competing effects on O5. On the protective side, removing violent and disruptive pupils from mainstream classrooms should improve the immediate safety of schools for remaining pupils and staff — the stated aim of ensuring schools 'can function safely' is plausible on its face. On the crime-pipeline side, the evidence is substantial: multiple sources confirm a strong correlation between exclusion and criminal justice involvement, and one study found permanent exclusion raises the probability of custody by 33 percentage points. A figure suggesting nine in ten young men in youth offending institutions had been excluded is cited from a single advocacy-linked source and should be treated as indicative rather than definitive, but the direction it points is consistent with the multi-source E13 and the E15 custody finding. The doubling of PRUs is the critical mitigating factor. If PRUs effectively diverted excluded pupils from criminal pathways, the net O5 effect could be neutral or positive. But the evidence on PRU quality is discouraging: only 1.1% of alternative-provision pupils achieved adequate GCSEs; placements frequently become permanent rather than a route back to mainstream; and staffing with specialist expertise is already strained — doubling capacity would likely worsen this. Poor educational outcomes sustain the crime-pipeline. The short-term school-safety gain is real but localised; the long-term community-crime risk is population-wide. Both are evidenced, making this genuinely mixed. Magnitude is moderate because the custody-probability effect is substantial even if causality is debated. Confidence is moderate because the exclusion-crime correlation is robust but the counterfactual — how much better expanded PRUs could perform — remains uncertain.

Education & opportunity — Hurts

moderate · moderate confidence

Increasing permanent exclusions will likely harm the educational opportunities of the most vulnerable pupils — who are disproportionately poor, disabled, or from ethnic minorities — since excluded children face catastrophically worse outcomes and PRUs are ill-equipped to absorb the extra demand. There is no evidenced upside strong enough to offset this harm.

The evidence

Biggest unknown: Whether doubling PRUs could genuinely deliver quality provision at scale, or whether chronic staffing shortages and poor outcomes mean excluded pupils simply fall further behind.

Our reading: The evidence points consistently in one direction: increased permanent exclusions worsen educational outcomes and opportunity, especially for the most vulnerable pupils. The policy's stated aim — safer schools and best practice via PRUs — is plausible in theory, but there is no evidenced upside in the provided research to set against the documented harms. The only positive framing comes from the policy's own stated text, not from research on outcomes. The distributional harm is stark. Exclusions already fall overwhelmingly on disadvantaged pupils (two-thirds are FSM-eligible), those with SEN (four times more likely to be excluded), and certain ethnic minorities. A policy of increased exclusions, without any stated measures to address these underlying drivers, will widen the attainment gap — the opposite of what O7 requires. The educational outcomes for excluded children are catastrophic: only 1.1% of alternative provision students achieved five good GCSEs versus 53.5% in mainstream, and 90% of those excluded from primary school fail core GCSEs. Permanent exclusion raises the probability of custody by 33 percentage points. These are not marginal effects. Doubling PRUs is presented as the mitigation, but existing PRUs already face inadequate accommodation, specialist staff shortages, and high turnover. Doubling capacity without solving these structural problems risks creating more under-resourced placements. PRU placement also tends to become permanent rather than a temporary bridge back to mainstream, further cementing disadvantage. On O7's criteria — school standards, attainment gap, and opportunity for poorer pupils — the evidence points to a moderate worsening, concentrated among those who are already worst-off.

Equal treatment & democratic rights — Hurts

moderate · moderate confidence

Increasing permanent exclusions would fall hardest on children who already face disadvantage — those with special educational needs, Black and Gypsy/Roma pupils, and those from low-income families — deepening unequal treatment in education. The evidence on disproportionate exclusion rates for these groups is consistent, though the exact scale of worsening depends on how many additional exclusions occur.

The evidence

Biggest unknown: Whether doubling PRUs genuinely absorbs excluded pupils into quality provision, or whether placements become effectively permanent, determines how severe the equal-treatment harm is for affected groups.

Our reading: O9 covers equal treatment and anti-discrimination protections. The policy's central mechanism — increasing permanent exclusions — operates on a baseline where exclusion is already highly unequal in its incidence. SEN pupils, pupils from low-income families, and pupils from certain ethnic minority groups (Gypsy/Roma, Black Caribbean) are excluded at rates many multiples above the average. A policy that drives more exclusions overall will, absent any targeted safeguard, amplify this differential impact. The policy text contains no mechanism to counter the documented disparity — no requirement to monitor disproportionality, no SEN carve-out, no equality impact commitment. The stated goal of doubling PRUs does not address the equal-treatment problem: evidence indicates PRU placements often become permanent rather than acting as a bridge back to mainstream education, meaning the groups already most excluded face a higher probability of being tracked into a lower-quality, segregated educational pathway. This is a structural equal-treatment concern, not just an educational-outcomes concern. The magnitude is moderate rather than major because the policy affects a subset of the school population, and the direction of exclusion growth is already occurring without this policy; the marginal harm is real but not transformative of the entire system. Confidence is moderate: the disproportionality data is robust and consistent across institutional sources, but the exact magnitude of additional exclusions the policy would generate — and whether doubling PRUs meaningfully mitigates harm — is uncertain.
