The One* Service brings together five nonprofit service providers, and has the ability to engage other providers according to the individual needs of its clients. Working with offenders both pre- and post-release, it provides a holistic service including support with housing, training and employment, parenting, substance abuse, and mental health problems. The service aims to reduce the reconviction rate of the target population relative to a comparison group. Each member of the intervention cohort is matched with offenders with similar characteristics and offending histories, and the frequency of reconviction events are compared post release.
