There are positive indications that accredited programmes may be effective in reducing re-offending for offenders in the community. The re-offending rate for all offenders who had undertaken interventions was 55 per cent., based on a two-year reconviction rate. Programme completers did statistically significantly better than those who did not start or who dropped out of programmes. The rates were 38 per cent., 61 per cent. and 64 per cent. respectively.
A recent prison-based study showed that the one-year reconviction rate for both adult men and young offenders who had completed enhanced thinking skills (ETS) and reasoning and rehabilitation (R+R) interventions in prison represented a positive 2.5 percentage points difference in reconviction for adult male completers (17.0 per cent. vs. 19.5 per cent.) and a 4.1 percentage point difference for young offender completers (31.4 per cent. vs. 35.5 per cent.) compared to matched comparison groups. There was no difference in reconviction rates between programme starters and comparison groups. See tables 3 and 4:
