Over the past several years, there has been much attention and advocacy around “PreK-3 Alignment,” both in California and nationwide. The push for alignment comes in the face of a growing body of research documenting the benefits of attending high quality preschool, along with concerns about the fading of the benefits of preschool by third grade that has been found in many studies. Supporters of preK-3 alignment note that child development is a continuous process, and that skills developed in one grade must be built upon and reinforced in later grades.
