Transitional Kindergarten (TK) is a relatively new model of early childhood education, with little evidence on whether and how it affects children's development. This study provides new evidence using data from Michigan, which has the nation's second-largest TK program. Using survey data (N=171) from administrators in 2021-2022, the paper…

Transitional kindergarten (TK) is a relatively recent entrant into the US early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on third-grade test scores. Using an augmented regression discontinuity design, we find that TK improves third-grade…

Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on 3rd grade test scores. Using an augmented regression discontinuity design, we find that TK improves 3rd grade…

Do Washington state's targeted, public preschool programs help socially vulnerable students succeed in elementary school? In this study, we explore this question by examining the state's Early Childhood Education and Assistance Program (ECEAP) and the Early Support for Infants and Toddlers (ESIT) program. Using statewide censuses of…

This study was intended to evaluate the impact of socioeconomically disadvantaged children's participation in the Texas home instruction for parents of preschool youngsters (TXHIPPY) program on their school readiness and academic achievement for grades K to eight. The study used a quasi-experimental design and applied optimal full propensity score…

We systematically examine the existing evidence and compute meta-analytic averages for the effects of scaled-up, publicly funded pre-kindergarten (pre-K) programmes in the United States on student mathematics and reading achievement. The analysis is restricted to experimental and quasi-experimental research designs with the highest internal…

Executive functions (EFs) are foundational for the development of cognitive and social capacities critical for school readiness. The importance of promoting EF skills prior to school entry is increasing recognized but few preschool classroom-based interventions specifically target EF skills. The aim of this study was to evaluate the effectiveness…

The purpose of this evaluation study was twofold: to evaluate the overall impact of an intensive early childhood literacy project on children's vocabulary knowledge and to examine the sociocultural context of the vocabulary assessment for the early literacy project. Children's language development and vocabulary knowledge was measured with PPVT-IV…

We present a reanalysis of the Tennessee Voluntary Prekindergarten Program (TNVPK), a state-funded program designed to promote the school readiness of 4-year-olds from low-income families. Oversubscribed programs used a lottery to randomly assign prospective enrollees a chance to attend TNVPK. We found that assignment to the program had largely…

This paper studies the impact of PROBEMS, a scholarship program in Mexico aimed at improving graduation rates and test scores among upper secondary school students from poor backgrounds. The identification strategy is the random allocation into the program, which took place in 2009. The strategy allows measurement of the effects of PROBEMS on test…

This paper examines the child development outcomes of two cohorts of children who were exposed to the same intervention at different points in time. One cohort was eligible to access playgroups during the first year of a five-year project cycle, beginning at age four. The other cohort became eligible to access these services during the third year…

Pre-school education has been greatly expanded in the United Kingdom in the last two decades and further expansion is planned. Its provision allows parents to take up employment thus increasing family incomes and it is expected to narrow the gap between socially disadvantaged children and their peers. The latter is important as studies have shown…

Since 2007, nineteen Houston Independent School District (HISD) campuses have partnered with Literacy Now to offer the Reading Intervention program. The Reading Intervention program provides individualized, small group reading tutorials for at-risk students in kindergarten to second grade to create proficient readers by the end of third grade.…

Data from a large suburban school district in Tennessee (N = 910) were used to examine the effects of the Kindergarten Readiness program as measured by third grade End of Year (EOY) benchmark performance assessments in reading and math. The groups of students studied included kindergarteners with summer birthdays ("SK"), kindergarteners…

Many states have implemented or expanded state-funded prekindergarten programs in the last decade, encouraged by claims about the benefits that can be expected and the importance of early experiences for children's development, especially for economically disadvantaged children. However, there is remarkably little methodologically adequate…
