All youth need the support of parents, family members, and other caring adults. Parents and families are children's first teachers and, in many respects, their most influential role models and motivators. Among the varied efforts to ensure that children succeed and thrive, there is growing acknowledgement of how critically important it is to engage parents and families and to intentionally create connections between schools and other community resources. This publication is designed to: (1) provide clarity on what systemic engagement is and what it looks like in practice; (2) provide an analysis of how systemic practices are being implemented in the family and community engagement field through exemplars of systemic engagement (district engagement briefs); (3) share promising practices that promote systemic engagement while leveraging engagement to advance equity (regional capacity-building models); and (4) provide insights and recommendations to practitioners, funders, policymakers, and other key constituencies regarding family engagement practices and potential areas for additional research.
