1) Reoffending rates whilst resident:

a) Shorter sentence subgroup

Of 30 residents; 14 came to Alpha House off a sentence of less than 12 months, (6 were exactly 12 months but we have to compare to national stats of “less than 12 months”). There was only one person who committed an offence whilst residing among the “less than 12 months last sentence” subgroup.

1 offender among 14=7%. That gives us 7.5 % reoffending rate whilst at AH per year amongst the “short sentence” group. By comparison, national stats for reoffending was 62.7%. So our short sentence group did 7.5 times better than the national short sentence group.

b) Longer sentence subgroup

Amongst this group, 1 person committed an offence whilst resident = 7.7%. However, the average stay at AH of that group was longer than 1 year (470 days) so we reduced that in proportion and that gives us a reoffending rate per year of 6%. The national rate for the longer sentences group was 28.7% for that year. So, whilst resident, the ‘longer sentence group’ did 4.8 times better than the national short sentence group.

2) Reoffending rates after leaving AH:

a) Shorter sentence subgroup

Of this 14, there were 4 ‘offenders’. Average time since leaving is 711 days among that group. Over 1 year the reoffending rate comes out at 14.9% after leaving AH. That compares with 62.7% nationally. So our group have done 4.2 times better than the national average for the ‘short sentence’ group since leaving AH.

b) Longer sentence subgroup

Of our 13, there were 4 ‘offenders’. Average time since leaving is 602 days for that group. Over 1 year the reoffending rate comes out at 18.8% after leaving AH.
That compares with 28.7% for the same group nationally. So our longer term group did 1.5 times better than the national average for longer sentence group.

3) Overall offending before Alpha versus since referral date:

From calculating number of recorded offences in total across the group versus cumulative time between first and last offence minus time spent in prison The average offending ‘rate’ across the group was 0.9 offences per year during the time between first and last offence whilst not in prison. Since referral to AH, the rate is 17 offences. That gives us 0.2 offences per year which is 4.5 times better than the national average.

Whilst resident figure is 2 offences = 0.06 offences per year = 15 times better than offences per year pre-AH time between first and last offence whilst not in prison.
After leaving there were 0.27 offences per year = more than 3 times better than pre-AH time between first and last offence whilst not in prison.
