The current study provides new evidence on the sustained benefits of preschool attendance on a broader range of skills--both academic and executive functioning (EF)--than many prior studies have examined. Using propensity score methods, we predicted children's (N = 920, M age at 1st = 6.5 years) literacy, language, math, and EF skills in…

Preschool improves children's kindergarten readiness, but the cognitive outcomes of preschool enrollees and nonenrollees tend to converge partially or fully in elementary school. In older programs, most of this convergence occurs in kindergarten (Li et al., 2016), but evidence from today's programs is sparse. Using data on 4,971 children who…

This study investigates whether children's preschool experiences are associated with later achievement via enhanced learning behaviors using data from a German longitudinal study following children (N = 554) from age 3 in preschool to age 8 in second grade. There were two main findings. First, results suggest that more positive learning behaviors…

This study explores children's early academic and self-regulatory skills as potential pathways through which a preschool enrichment program--the Chicago School Readiness Project (CSRP)--may contribute to low-income children's long-term outcomes (N = 466; M[subscript age] at baseline = 4.10 years). We find that CSRP's impact on high school grades…

A randomized controlled trial was used to examine the impact of an attachment-based, teacher-child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3-4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual…

Head Start (HS) is the largest federally funded preschool program for disadvantaged children. Research has shown relatively small impacts on cognitive and social skills; therefore, some have questioned its effectiveness. Using data from the Head Start Impact Study (3-year-old cohort; N = 2,449), latent class analysis was used to (a) identify…

Publicly funded prekindergarten programs have achieved small-to-large impacts on children's cognitive outcomes. The current study examined the impact of a prekindergarten program that implemented a coaching system and consistent literacy, language, and mathematics curricula on these and other nontargeted, essential components of school readiness,…

Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children's school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start-funded classrooms (N = 602 children). The analyses confirm that the CSRP…

Using data collected up to age 26 in the Chicago Longitudinal Study, this cost-benefit analysis of the Child-Parent Centers (CPC) is the first for a sustained publicly funded early intervention. The program provides services for low-income families beginning at age 3 in 20 school sites. Kindergarten and school-age services are provided up to age 9…

This study evaluated the relative effectiveness of home-based, community-based, and state-run early childhood programs across Cambodia. A total of 880 five-year-olds (55% girls) from 6 rural provinces in Cambodia attending State Preschools, Community Preschools, Home-Based Programs, or no programs were assessed twice using the Cambodian…

Responds to Scarr and McCartney's (1988) Bermudian study. Cites recently published research to support a conclusion that poverty alone does not predict school disadvantage so much as poor parents frequently having low motivation and less than high school graduation. (RJC)

The hypothesis was investigated that alleviation of negative motivational factors underlies much of the 10-point IQ increase commonly found in economically disadvantaged children's performance following a preschool intervention program. Head Start and non-Head Start groups were tested on IQ and motivational measures three times before and during…

Assessed the effects of preschool education on achievement in primary school for 88 impoverished African American children and their families. Found that the positive effects of a preschool intervention program on intellectual development and academic achievement were maintained through age 12 and that school-age intervention alone was less…
