State policymakers have worked hard to increase prekindergarten enrollment and ease young children's transition to kindergarten, and with good reason. There is abundant evidence that attending a formal preschool program such as state pre-K or Head Start boosts students' academic and social competencies significantly and meaningfully, regardless of…

This study examines the effects of universal public pre-kindergarten for 3-year-olds (Pre-K3) on later public education outcomes, including enrollment, school mobility, special education status, and in-grade retention from kindergarten through second grade. While universal pre-kindergarten programs typically target 4-year-olds, interest in…

In recent years, several states have expanded a new publicly funded learning option: Transitional Kindergarten (TK). TK bridges prekindergarten and kindergarten in its eligibility, requirements, and design. Using Michigan as a case study, we examine TK's fit in the early learning landscape. Broadly, we find TK in Michigan reduces some…

The transition from early intervention to preschool is a major early milestone for children with multiple disabilities and their families and the first of many transitions they will experience across the lifespan. However due to the low-incidence nature of multiple disabilities, this group has been largely left out of the literature surrounding…

As part of its effort to make universal prekindergarten (UPK) available to four-year-olds, California has recently expanded transitional kindergarten (TK) in its public schools. TK will be a full pre-K grade level in all districts by the 2025-26 school year. Other states that seek to broaden access to early care and education (ECE) can learn…
