Background: Universal Prekindergarten (UPK) programs often expand by offering Pre-K in both public schools and in community-based providers (CBOs). This approach gives families more options and allow UPK programs to increase access more quickly. However, little is known about which CBOs select into these systems. This is an important gap in the…

Pre-kindergarten (Pre-K) improves the school readiness of all children, but less is known about whether associations between enrollment in Pre-K and different indicators of social-emotional and executive functioning (EF) skills are sustained as children move into and across elementary school. The current study examines associations between…

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…

Lottery-based identification strategies offer potential for generating the next generation of evidence on U.S. early education programs. The authors' collaborative network of five research teams applying this design in early education settings and methods experts has identified six challenges that need to be carefully considered in this next…

Substantial research has documented that Pre-Kindergarten (Pre-K) programs have important benefits for the school readiness of young children, especially those from low-income backgrounds. Recent studies in this arena have taken advantage of the Regression Discontinuity (RD) design to evaluate the impacts of Pre-K, due to ethical and pragmatic…

Improved measurement of the active ingredients that promote children's gains in early childhood education programs is a topic of considerable interest to stakeholders. Accurate and reliable measurement of early childhood education experiences can aid policymakers, school administrators and educators in improving the quality of early education and…

This study examines whether associations between enrollment in public and non-public PreK and children's (N = 508; M[subscript age] = 5.60 years in fall of kindergarten) math and language and literacy outcomes were more likely to be sustained through the spring of kindergarten for unconstrained versus constrained skills. Associations between…

The sustaining environments hypothesis theorizes that the lasting effects of PreK programs are contingent on the quality of the subsequent learning environment in early elementary school. The current study tests this theory by leveraging data from students (N = 462) who did and did not enroll in the Boston Public Schools (BPS) prekindergarten…

Currently available measures of PreK classroom quality inconsistently predict gains in children's outcomes. Extant measures may not capture the full range of instructional practices--including the degree to which children are exposed to rich content and cognitively demanding instruction--that are important for supporting the development of early…

This study leverages six years of public prekindergarten (pre-K) and kindergarten data (N = 22,469) from the Boston Public Schools (BPS) to examine enrollment in BPS pre-K from 2012-2017 for students from different racial/ethnic, socioeconomic, and linguistic groups. The largest differences in enrollment emerged with respect to race and…

Much of the currently available evidence on the causal effects of public prekindergarten programs on school readiness outcomes comes from studies that use a regression-discontinuity design (RDD) with the age cutoff to enter a program in a given year as the basis for assignment to treatment and control conditions. Because the RDD has high internal…

Theory and empirical work suggest inclusion preschool improves the school readiness of young children with special needs, but only 2 studies of the model have used rigorous designs that could identify causality. The present study examined the impacts of the Boston Public prekindergarten program-which combined proven language, literacy, and…
