Increasingly, the child welfare system is acknowledging the importance of incorporating parent voice and expertise into changes in child welfare practice, policy, and research; however, there is limited knowledge on how to incorporate parents’ expertise into program-level change. This study sought input from parent partners on the shared principles of a statewide coaching program for child welfare supervisors. Two focus groups were conducted, an initial focus group (n = 17) and a member checking focus group (n = 14). Data were analyzed using thematic analysis. Findings included three key themes: (a) understand parent context, (b) activate engagement, and (c) bridge principles and practice. Strategies for incorporating parent partner input into the coaching program are discussed.
