Pre-kindergarten (Pre-K) programs typically improve early academic skills, but those gains too often disappear after children transition to elementary school. At least three hypotheses explain this "fade-out" of Pre-K effects: Pre-K does not focus on the "trifecta skills" that uniquely support subsequent learning and…

The present study reports associations between features of directly observed classroom processes and school readiness skills across the academic year for 1498 children enrolled in publicly funded pre-K programs in a large and diverse county. In models adjusting for a range of child and family covariates, evidence was detected for the separate, and…

One widely used tool that captures the process quality of preschool classrooms, including interactions between teachers and children, is the Classroom Assessment Scoring System-Preschool (Pre-K CLASS; Pianta et al. 2008). The Bill & Melinda Gates Foundation funded Mathematica to conduct a literature scan to search for recent studies analyzing…

Research Findings: The aim of the current study was to examine the extent to which the effects of preschool classroom quality on children's mathematics is moderated by executive functioning (EF) during the preschool year. The study sample included 102 children (M age = 53.57 months [SD = 5.42]; 49% male) and one of their parents recruited from 26…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

A classroom randomized efficacy trial conducted over four years in 7 community-based preschool and 6 Head Start programs investigated effects of the Second Step Early Learning (SSEL) curriculum on end of preschool executive functioning (EF) and social-emotional (SE) skills in low-income children. Outcomes are reported for n=770 four-year-olds…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This fifth short report in a series highlighting findings from the Study of…
