With most 4 year olds in the United States now in center-based early care, the need for aligning instruction from preschool through the early grades (PK-3) has become more pressing. Yet so far there has been little guidance on how to create alignment. Research on PK-3 alignment seeks to provide general principles for creating instructional…

"PK--3" has become a rallying cry among many developmental scientists and educators. A central component of this movement is alignment between preschool and the early elementary grades.

Although there is considerable research on the elements of high-quality preschool and its many benefits, particularly for low-income children and English learners, little information is available to policymakers about how to convert their visions of good early education into on-the-ground reality. This brief summarizes a study that fills that gap…

Early education has emerged as a critical issue for state policymakers, who during the 2015-16 fiscal year alone invested nearly $7 billion in programs for our country's youngest learners.
