This sequential mixed methods study evaluated the impact of the Chicago Parent Program (CPP) in 12 Baltimore Title I PreK programs on parent engagement and student outcomes from kindergarten through 2nd grade. Phase 1 (quasi-experiment; N = 11,996) compared PreK students whose parents enrolled in CPP with those whose parents did not enroll in CPP…

Research Finding: The present study estimates the long-term effects of Chile's national public Early Childhood Care and Education program (ECCE) on children academic achievement, grade retention and school dropouts, to better understand if ECCE is helping reduce the socioeconomic achievement gap. The present study uses a quasi-experimental design…

This paper evaluates the impact of extension of the school day in the context of Brazil's "Mais Educação" Extended School Day Program. Using school level longitudinal data, we find that the program reduces the dropout rates of students in all grade levels, raises the enrollment of students in grades 6-9, but reduces the enrollment of…

The Arkansas Better Chance (ABC) program longitudinal study (2009-2020) reviews the changing circumstances and outcomes of participation in Pre-K services in Arkansas. The "core comparison" of this study is between ABC participants and students who had no known Pre-K participation but have similar household income levels. The results…

As states have upgraded their commitment to pre-K education over the past two decades, questions have arisen. Critics argue that program effects are likely to fade out or disappear over time, while supporters contend that program effects are likely to persist under certain conditions. Using data from Tulsa Public Schools, three neighboring school…

As pre-K programming increasingly garners more political attention and funding in the states, policymakers are seeking the most up-to-date and rigorous research to support decision-making and creation or expansion of these programs. High-quality pre-K has bipartisan support in part because of the vast amount of existing research detailing positive…

Social-Emotional Learning (SEL) programs are school-based preventive interventions that aim to improve children's social-emotional skills and behavioral development. Although meta-analytic research has shown that SEL programs can improve academic and behavioral outcomes in the short term, few studies have examined program effects on receipt of…

North Carolina's Smart Start and More at Four (MAF) early childhood programs were evaluated through the end of elementary school (age 11) by estimating the impact of state funding allocations to programs in each of 100 counties across 13 consecutive years on outcomes for all children in each county-year group (n = 1,004,571; 49% female; 61%…

In the past 15 years, four-year-olds' enrollment in state-funded prekindergarten in the United States has more than doubled, with roughly one-third now enrolled. Although researchers have found that early childhood programs from decades ago had sizable benefits for students that lasted into adulthood, evidence from more recent (and less expensive)…

"The No Child Left Behind Act of 2001" (NCLB) made schools accountable for student performance through standardized testing. Some claim high-stakes testing is an inexpensive vehicle through which to raise educational standards, however, these studies typically count only the administrative costs of test development, test delivery, and…

Recently, researchers have begun to employ rigorous statistical methods and developmentally-informed theories to evaluate outcomes for students retained in non-kindergarten early elementary school. However, the majority of this research focuses on academic outcomes. Gaps remain regarding retention's effects on psychosocial outcomes important to…

North Carolina's Early College model is the subject of an IES-funded eleven-year longitudinal experimental study that utilized a lottery process to assign early college applicants to either treatment or control groups. This paper presents findings related to high school outcomes. The primary goal of the early college model is to increase the…

This article examines the impacts of summer instruction and test-based grade retention in New York City. We use a research design that exploits test score cutoffs used in assignment to these treatments. We find modest positive effects of summer instruction on English language arts (ELA) achievement for students assigned to summer instruction…

This paper presents results from the longitudinal experimental study conducted on North Carolina's early college model described in an earlier paper. The primary purpose of this paper is to present the impact of the early college model on outcomes related to postsecondary enrollment. The specific research questions driving this study include: (1)…

This study presents evidence pertinent to current debates about the lasting impacts of early childhood educational interventions and, specifically, Head Start. A group of students who were first studied to examine the immediate impacts of the Tulsa, Oklahoma, Community Action Project (CAP) Head Start program were followed-up in middle school,…
