1. Main points


This publication provides the final proven reoffending results for the April to June 2020 offender cohorts managed by Community Rehabilitation Companies (CRC) and the National Probation Service (NPS). Although CRC contracts ended and a new unified model[footnote 1] for Probation Services was introduced in England and Wales at the end of June 2021, reporting of the reoffending results will continue until the measurement period of proven reoffending for all offender cohorts managed by the CRCs and the NPS has come to an end; this is due to the time lags inherent in the proven reoffending measure.

April to June 2020  
Eighteen CRCs achieved significant reductions in the binary rate Eighteen of the 20 CRCs managing offenders in the April to June 2020 cohort achieved statistically significant reductions in the adjusted binary rate (i.e. the proportion of offenders who reoffend) when compared to the 2011 baseline. None of the CRCs saw significant increases in the adjusted binary rate.
Decrease in the overall NPS binary rate The overall binary rate for offenders managed by the NPS was 34.2%, representing a 3.3 percentage point decrease compared to October to December 2015.
Decrease in the overall NPS frequency rate The overall frequency rate for offenders managed by the NPS decreased by 1.2% to 3.92 reoffences per reoffender compared to October to December 2015.

2. Statistician’s comment


“This report covers final proven reoffending results for the April to June 2020 offender cohorts managed by CRCs and the NPS. A proven reoffence is measured over a one-year follow-up period and a further six-month waiting period to allow the offence to be proven in court.[footnote 2]

This latest offender cohort represents the first for which the cohort period itself overlaps entirely with the first national lockdown due to the pandemic; this included court closures leading to sharp decreases in the number of cases processed at the criminal court.[footnote 3]

The reoffending follow-up and waiting periods for this cohort also continue to overlap with both the second and third national lockdowns.[footnote 4] While there were no court closures during these two latter lockdowns, police recorded crime data have shown overall reductions in the reporting and recording of many crime types during periods of lockdown.[footnote 5]

As a result, the volumes of offenders and reoffenders across both CRCs and the NPS for this latest cohort represent the lowest since October to December 2015.[footnote 6]

Of all 20 CRCs[footnote 7] managing offenders in the April to June 2020 cohort, 18 achieved statistically significant reductions in the adjusted binary reoffending rate when compared to the 2011 baseline reoffending rates, whilst none saw any statistically significant increases.

The overall binary reoffending rate for offenders managed by the NPS was 34.2%, representing a 3.3 percentage point decrease compared to October to December 2015. NPS South East and Eastern has the highest frequency rate at 4.54 reoffences per reoffender, while NPS London has the lowest at 3.47 reoffences per reoffender.

Figures for this latest offender cohort period are now showing a more pronounced impact of the pandemic on offender and reoffender volumes. However, during this period of volatility, the proven reoffending rates are likely to continue oscillating in the short-term before potentially more stable trends are observed as we move further away from the periods of lockdowns.”


3. Introduction


This publication provides the final proven reoffending results for the April to June 2020 offender cohorts managed by CRCs. Although CRC contracts ended and a new unified model[footnote 8] for Probation Services was introduced in England and Wales at the end of June 2021, reporting of the reoffending results will continue until the measurement period of proven reoffending for all offender cohorts managed by the CRCs and the NPS has come to an end; this is due to the time lags inherent in the proven reoffending measure. The results presented in this bulletin in relation to offenders managed by CRCs will focus on comparison against the baseline period, rather than any impact on financial implication.

Results presented reflect the changes to the CRC contracts,[footnote 9] announced in 2018, which resulted in an adjustment to the binary measure and a change to the frequency baseline[footnote 10] against which CRCs are compared.

The one-year proven reoffending measures used to assess CRC performance are:

  • the binary rate (proportion of offenders who reoffend); and
  • the frequency rate (the average number of reoffences per reoffender)

The binary rate for each CRC is subject to an adjustment for changes in the case mix of offenders being supervised, using the Offender Group Reconviction Scale (OGRS), version 4/G,[footnote 11]; this was to allow performance to be assessed against the baseline year of 2011.[footnote 12] This is referred to as the OGRS4/G-adjusted binary reoffending rate.

The publication also includes final results for the NPS. However, please note that final results for the NPS have not changed as a result of the contract variations since they are not compared against a baseline threshold in the same way.

3.1 Contract variation

Under contract variations, the following changes have been made to the binary and frequency measures, for assessing CRC performance:

  1. An additional adjustment has been made to the OGRS4/G-adjusted binary reoffending rate to account for a change in the data source in October 2015, as explained in the published technical note.[footnote 13]

  2. As announced in the ‘Strengthening probation, building confidence’ consultation document,[footnote 14] the baseline year, against which CRC performance on the frequency of reoffending is compared, changed. All CRCs are now compared against a 2015/16 baseline, with the exception of Merseyside CRC, which has retained the 2011 baseline.

Both adjustments were applied retrospectively to all final CRC cohorts in the October 2018 bulletin.[footnote 15]

To aid the user, and in the interests of transparency, the accompanying tables include the actual binary rates before any adjustments alongside the OGRS4/G-adjusted binary rates and 2018 contract-adjusted binary rates.

From this point forward, the 2018 contract-adjusted binary rate will be referred to as the adjusted binary rate.

For technical detail on how proven reoffending is measured, please refer to the accompanying guide to proven reoffending statistics.[footnote 16]


4. Final results


Final results are based on a cohort of offenders who were managed by CRCs in the community under Payment by Results (PbR) arrangements, and by the NPS. All offenders have been subject to the full one-year follow-up period and the additional six-month waiting period as detailed in the guide to proven reoffending statistics.[footnote 17]

Reporting of proven reoffending rates for offenders who were managed by CRCs is based on comparisons with 2011 baseline reoffending rates. Comparisons of performance between different CRCs and previous cohorts can be made by comparing the adjusted binary rates. Commentary on proven reoffending rates for offenders who were managed by the NPS is based on comparisons against the October to December 2015 offender cohort, i.e. the first cohort for which reoffending rates were measured since the start of Transforming Rehabilitation.[footnote 18] Comparisons cannot be made between CRCs and the NPS due to differences in the offenders being managed.


4.1 April to June 2020 offender cohorts

Unlike previous cohorts which had been affected to varying degrees by the pandemic, the April to June 2020 offender cohort is the first for which the cohort period itself overlaps entirely with the first national lockdown due to the pandemic; this included court closures leading to sharp decreases in the number of cases processed at the criminal court.[footnote 19]

The reoffending follow-up and waiting periods for this cohort also continue to overlap with both the second and third national lockdowns.[footnote 20] While there were no court closures during these two latter lockdowns, police recorded crime data have shown overall reductions in the reporting and recording of many crime types during periods of lockdown.[footnote 21]

As a result of these circumstances, the volumes of offenders and reoffenders across both CRCs and the NPS for this latest cohort represent the lowest since October to December 2015 (excludes NPS Wales due to the early transition of offenders from CRC supervision during the time series).

More specifically, across CRCs, the reduction in the cohort size since January to March 2020 has ranged from 40.2% for Derbyshire, Leicestershire, Nottinghamshire and Rutland to 62.2% for Hampshire and Isle of Wight. Similarly, the number of subsequent reoffenders also decreased with the reductions ranging from 30.1% for Northumbria to 55.3% for Warwickshire and West Mercia.

Although declines in the volumes of offenders and reoffenders are not as acute, the latest equivalent figures across NPS regions (excludes NPS Wales due to the early transition of offenders from CRC supervision during the time series) also represent the largest quarterly reductions. The decreases in the number of offenders ranged from 13.1% for NPS Midlands to 29.1% for NPS North West, whilst the decreases in the number of reoffenders ranged from 13.9% for NPS London to 29.1% for NPS North West.

In terms of the adjusted binary rate, 18 of the 20 CRCs[footnote 22] achieved statistically significant reductions for the April to June 2020 cohort when compared to the 2011 baseline reoffending rates (Figure 1). None of the CRCs saw a statistically significant increase in the adjusted binary rate.

Final adjusted binary rates for the **April to June 2020** offender cohorts, by CRC (Source: Table A1, Final proven reoffending statistics for CRCs and the NPS, April to June 2020, England and Wales)

The overall binary reoffending rate for offenders managed by the NPS was 34.2%, representing a 3.3 percentage point decrease compared to October to December 2015. Over this period, all NPS regions saw reductions (ranging from 2.3 percentage points for NPS South East and Eastern to 10.5 percentage points for NPS Midlands) in the binary rate, with the exception of NPS North East which saw an increase of 0.6 percentage points. Furthermore, in the latest cohort, NPS Wales continues to have the highest binary rate at 40.5%, while NPS Midlands has the lowest at 28.5% (Figure 2).

The overall frequency rate for the April to June 2020 cohort decreased by 1.2% to 3.92 reoffences per reoffender compared to October to December 2015. Regionally, NPS Wales and NPS South East and Eastern saw increases of 2.5% and 11.3% respectively in the frequency rate over the same period, while the remaining five NPS regions saw decreases ranging from 1.0% for NPS Midlands to 6.9% for NPS North East. NPS South East and Eastern has the highest rate at 4.54 reoffences per reoffender. Meanwhile, NPS London has the lowest at 3.47 reoffences per reoffender.

  22. Note that in this and future quarterly cohorts, there will be no results for Wales CRC as offender management transferred to NPS Wales in December 2019. 

  23. There are no results for Wales CRC as, under the Probation Reform Programme, offender management transferred to NPS Wales in December 2019. 

  24. Under the Probation Reform programme, offender management transferred from Wales CRC to the unified model area of NPS Wales in December 2019. As a result, lower risk offenders previously managed by Wales CRC transitioned over to NPS Wales and so figures for the latter are not directly comparable to other NPS divisions.
