Harvard Family Research Project (HFRP) and the National Parent-Teacher Association (PTA) have teamed up to bring you a ground-breaking policy brief that examines the role of school districts in promoting family engagement. "Seeing is Believing: Promising Practices for How School Districts Promote Family Engagement" spotlights how six school districts across the country have used innovative strategies to create and sustain family engagement "systems at work." Drawing from districts' diverse approaches, we highlight promising practices to ensure quality, oversight, and impact from their family engagement efforts. Researchers propose a set of recommendations for how federal, state, and local policies can promote district-level family engagement efforts that support student learning. One appendix is included: (1) Overview of Six School Districts Profiled. (Contains 10 endnotes.)
