As is the case in the UK, formal police–community corrections partnerships in the US have existed since the 1990s. However, unlike the UK where parliamentary developments and subsequent policy initiatives have provided a context in which criminal justice agencies formally work together, police–probation/parole partnerships in the US have experienced relatively little formalisation, with most extant partnerships existing informally based principally on interpersonal relations between individual police and corrections agency members.

Findings are compared with research findings in the UK and Canada.
