There is growing evidence that reunifying children with their birth families is often unsuccessful. UK figures suggest that around 30 percent of reunified children will return to care within five years. Insights from evaluations of successful reunification programs are needed to develop effective reunification practices, however with the exception of the evaluation of the Newpin program in NSW, little Australian research has investigated programs which have had a positive impact on post reunification outcomes such as preventing future maltreatment or future re-entry into care. This paper will review evidence from some well evaluated US programs. It will also summarise key findings from an evaluation of Newpin.
