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…

This document compiles information from multiple sources to offer readers a snapshot of Preschool Development and Expansion Grant (PDG) states' progress towards implementing a full comprehensive assessment system, as well as the tools they are using for each of the components.

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…

This study includes a randomized control experiment, but that component could only be implemented in a limited number of schools with more applicants than seats in the pre-k program. Informative as that component is about the effects of Tennessee Voluntary Pre-Kindergarten (TN-VPK), the participating schools do not provide a representative sample…

In 2009, Vanderbilt University's Peabody Research Institute, in coordination with the Tennessee Department of Education's Division of Curriculum and Instruction, initiated a rigorous, independent evaluation of the state's Voluntary Prekindergarten program (TN- VPK). TN-VPK is a full-day prekindergarten program for four-year-old children expected…

This research investigated the effects of two contrasting pre-k curricula, relative to practice as usual, on subsequent academic achievement. One curriculum had a strong literacy focus, the other was a less didactic "developmentally appropriate" curriculum that allowed children to have more influence on classroom activities. The purpose…
