The purpose of this study was to identify barriers and facilitators to family engagement in schools implementing schoolwide positive behavioral interventions and supports (PBIS). Participants consisted of 1 representative member each from 204 school PBIS teams across 3 states. Qualitative analysis guided examination of responses to 1 question regarding barriers and 2 questions about facilitators to family engagement. Survey respondents identified key barriers to family engagement as a lack of resources, inconsistent communication, and reluctance of families and school staff to partner. Specified facilitators included communication, PBIS, shared decision-making, and strategies to build relationships with families.
