This two-part paper examines the early care and education (ECE) and K-12 research literature in depth to assess the current state of knowledge about the effective preparation of excellent teachers, and charts a research and policy agenda for the future.

Part I. Teacher Preparation and Professional Development in Grades K-12 and in Early Care and Education

Differences and Similarities, and Implications for Research

Part I summarizes the differences between the K-12 and the early care and education fields. We found more than enough similarities to warrant a close consideration of the combined wisdom of both fields.

Part II. Effective Teacher Preparation in Early Care and Education

Toward a Comprehensive Research Agenda

Part II contains an in-depth review of our ECE and K-12 teacher preparation research and outlines what remains to be learned. It concludes with a set of key recommendations for research and policy.
