Abstract: The Harvard Family Research Project has compiled and categorized recent resources about family involvement, including resources about parenting practices to support children’s learning and development, home–school relationships, parent leadership development, and collective engagement for school improvement and reform. The guide represents the work of 126 national organizations, as well as many state and local organizations whose family involvement initiatives have gained a national reach in terms of training activities, research, and program replication. Charter school founders, leaders, and teachers can use it to find resources to strengthen family–school–community partnerships. The guide is designed to help inspire capacity building and provide ideas for adapting family involvement activities and resources for more effective and relevant practice.
