The current alcohol arrest referral (AAR) pilots in Manchester, Liverpool, Ealing and Chester are subject to a vigorous evaluation process. This is being conducted by external evaluators from Liverpool John Moores University and Risk Solutions consultancy. Preliminary findings on re-offending data six months post-intervention and the throughput figures for offenders referred/receiving interventions will be received from the external evaluators in December 2008, with the final report due in July 2009.
