In 2026, a critical analysis by Ian Acheson has highlighted a twenty-five-year “national experiment” by the Ministry of Justice that prioritised ideological optimism over empirical evidence. The Sex Offender Treatment Programme (SOTP), launched in 1992, was marketed as a “civilised” solution to transform predatory men into manageable citizens. However, long-term data suggests the programme was not only ineffective but may have actively increased the risk of reoffending.
The investigation established that for decades, prison governors and parole panels treated the completion of SOTP as a “badge of progress.” The prosecution of the programme’s efficacy reported that the evidence base was “notably thin” from the outset, relying on small, uncontrolled studies with short follow-up periods. By the time a large-scale evaluation was conducted, it became clear that the state had been relying on a flawed rehabilitative orthodoxy.
The 2017 Evaluation and Internal Warnings
The court of public records reported that in 2017, the MoJ published a massive impact evaluation matching 2,562 treated men against 13,219 untreated offenders. The investigation established that 10% of those who completed the “treatment” were reconvicted of a sexual offence, compared to only 8% of the untreated group. For those convicted of indecent image offences, the failure was even more pronounced (4.4% vs 2.9%).
The prosecution reported that internal warnings had been raised as early as 2012 by MoJ analyst Kathryn Hopkins. Her research, which utilised propensity score matching, indicated that SOTP participants were more likely to reoffend. Instead of acting on these “protected disclosures,” senior managers reportedly marginalised Hopkins, marking her down in performance reviews—a move later condemned by an employment tribunal.
Long-Term Risk and “Entrenched” Offenders
While some meta-analyses suggest modest reductions in recidivism for general sexual offenders, the investigation established that there is no robust evidence that therapy works for “entrenched” adult contact child sex offenders. The prosecution reported that official reoffending figures—often cited at 2% to 3% over two years—are heavily limited by under-reporting and the short duration of the follow-up.
- The Reality of Recidivism: Longer-term studies of registered sex offenders have found reoffending rates as high as 55%.
- The “Treatment Effect” Fallacy: Some experts suggest that group therapy sessions may actually provide predators with new “scripts” for grooming or allow them to refine their deceptive techniques.
- The Duty of Care: Critics argue that the state’s primary duty is not the rehabilitation of the offender, but the lifelong protection of children.
Status of National Treatment Policy
Based on the judicial and administrative shifts reported in 2026:
- Core SOTP Status: DISCONTINUED (Scrapped in March 2017 following the negative evaluation).
- Replacement Programmes: Active (New models have been implemented, though critics argue the underlying “faith in treatment” remains unchanged).
- DBS/Vetting Impact: Convictions remain permanent; programme completion is no longer viewed as a definitive reduction in risk.
- Legal Framework: Shift towards “lifelong coercive restriction and control” for high-risk contact offenders.
- Judicial Oversight: Parole Board (Increasingly sceptical of rehabilitative claims for entrenched child abusers).
- Current Monitoring: Multi-Agency Public Protection Arrangements (MAPPA).
Monitoring and Public Protection
Offenders previously “treated” under the SOTP are managed under the statutory requirements of the National Probation Service and local police units. Due to the nature of the 2017 findings—specifically that “treatment” may have increased risk—these individuals are a priority for rigorous monitoring. Authorities reported that the 2026 analysis by Acheson reinforces the need for a “presumption of lifelong control” rather than a reliance on psychological interventions.
As of 2026, the Ministry of Justice faces ongoing pressure to prioritise chemical suppression of libido, intensive GPS monitoring, and practical situational risk reduction over group-work therapy. Authorities state that the failure of the SOTP serves as a “case study in institutional optimism.” Any failure to acknowledge the lack of evidence for “treating” child predators will result in immediate intervention by oversight bodies to ensure that public safety is not sacrificed for rehabilitative ideology.
QUESTION – Given that the MoJ’s own data suggests that sex offender treatment programmes may actually increase reoffending rates, do you believe that “completion of a treatment course” should be legally prohibited from being used as a factor in favour of an offender’s early release?
