A research-based early childhood curriculum is consistent with current studies on how children develop and learn. In Head Start programs, it must also be aligned with the Head Start Early Learning Outcomes Framework: Ages Birth to Five (ELOF). A research-based curriculum is content-rich, providing broad and varied experiences and activities that promote children's learning and development. It invites children to think deeply about what interests them and builds on their prior knowledge and experiences. It also offers a sequence of learning experiences based on children's developmental progressions. Find resources for selecting and implementing a research-based curriculum. Learn how to support teachers, family child care providers, and home visitors as they implement research-based curricula and teaching practices in Head Start programs.
