"Pre-K Mathematics" is a supplemental mathematics program focusing on a range of mathematical concepts to help develop children's informal mathematical knowledge. The "Pre-K Mathematics" program includes teacher-led, small-group mathematics activities that are engaging and hands-on, as well as caregiver-child activities that…

Research Findings: This study evaluated the effects of an early mathematics intervention designed to engage preschool children, their teachers, and their families in an interactive mathematics game. Previous research shows that playing this specific type of linear board game results in increased numerical skills and understanding in young children…

Decades of research on early care and education have shown that four-year-old children who enroll in prekindergarten (pre-K) programs start kindergarten scoring higher on assessments of academic skills than those who do not. A handful of long-term follow-up studies of pre-K have also found that these programs can have lasting beneficial impacts on…

This study examines growth in language and math skills during the summer before kindergarten; considers variation by family income, race/ethnicity, and dual language learner status; and tests whether summer center-based care sustains preschool gains. Growth in skills slowed during summer for all children, but the patterns varied by domain and…

State-funded prekindergarten (preK) programs are increasingly common across the country. This study estimated the effects of eight state-funded preK programs (Arkansas, California, Michigan, New Jersey, New Mexico, Oklahoma, South Carolina, and West Virginia) on children's learning using a regression discontinuity design. These programs vary with…

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 age at baseline = 4.10 years). We find that CSRP's impact on high school grades may be…

Two-year, play-based, full-day kindergarten (FDK) has been shown to have long-term academic and self-regulation benefits for young children. This article addresses the question of whether FDK has particular benefits for children who may be at risk for placement in special education. Participants included 592 kindergarten children in their second…

Head Start and state prekindergarten (pre-K) programs can boost the school readiness of low-income children through the use of effective preschool curricula. Encouraging results from some studies suggest that children who receive targeted or content-specific curricular supplements (e.g., literacy or math) during preschool show moderate to large…

The Massachusetts Preschool Expansion Grant (PEG) model supported and expanded high-quality preschool in high-needs communities. PEG required shared governance between local school districts and Massachusetts Department of Early Education and Care-licensed community-based programs. The 48 PEG classrooms provided free prekindergarten for…

Enrollment in state-funded pre-K programs prior to kindergarten entry has become increasingly common. As each state develops its own model for pre-K, rigorous studies of the impacts of state-specific programs are needed. This study investigates impacts of the Arkansas Better Chance (ABC) initiative at kindergarten entry using a…

Determining the effectiveness of many special education interventions is most difficult because of the practical and ethical limitations associated with assigning participants to a control or non-treated group. Using Longitudinal Study of Australian Children data, this article utilised eight different propensity score analysis methods to determine…

Research Findings: This study examined the impact of MyTeachingPartner-Math/Science, a system of math and science curricula and professional development, on the quality of teachers' interactions with children in their classrooms. Schools were randomly assigned to 1 of 2 intervention conditions (Basic: curricula providing within-activity, embedded…

Using data from a nationally representative sample, this study examined Head Start children's school outcome differences by the end of Kindergarten between children who attended Head Start program for two years and the ones who attended for one year. Propensity scores were used to match children who experienced different durations of the program…

The 1998 reauthorization of Head Start called for a national evaluation of the Head Start program. The goal of Head Start is to improve the school readiness skills of low-income children. Yet characteristics of Head Start programs, such as their quality and the amount of time children spend in them may influence their effectiveness at achieving…

This paper uses data from the Head Start Impact Study (HSIS), a nationally representative multisite randomized trial, to quantify variation in effects of Head Start during 2002-2003 on children's cognitive and socio-emotional outcomes relative to the effects of other local alternatives, including parent care. We find that (1) treatment and control…
