This Casey Family Programs issue brief looks at the use of peer mentors (“parent partners”) who work with parents entering in and engaging with the child welfare system. These parent partners have already encountered and worked with the child welfare system themselves, and the mentoring that they offer can encourage and instill hope for parents initially interacting with the system. The brief outlines these parent partner programs’ benefits and program research evaluation findings, and provides guidance on how these programs are structured and funded. It also provides brief summaries of three parent partner programs: Parents Anonymous®, the Kentucky Sobriety Treatment and Recovery Team (START) Program, and Iowa’s Parent Partner Program.
