Professional development (PD) is more effective when it involves more than lead classroom teachers. Collaborative Math is a year-long professional development program designed to bring together preschool center leadership and all teaching staff for an in-depth study of early mathematics teaching and learning. We implemented the program in a total of 15 Head Start centers across two years. We found positive shifts in teacher confidence and knowledge as well as child math achievement.
