This study examines "First 10 Schools and Communities"--coordinated efforts to improve teaching, learning, and care during the first decade of children's lives. First 10 initiatives take two basic forms. First 10 School Hubs are anchored by a single elementary school, which provides direct support to families and collaborates with nearby early childhood providers. First 10 Community Partnerships bring together multiple elementary schools, school district leaders, and early childhood programs to improve the quality and coordination of early childhood education and care throughout a geographic area or community.
