High-quality learning environments are critical to support students' learning and development. This study supported eight lead teachers of Starting Strong classrooms in four different early learning programs to try to improve teachers' knowledge, self-efficacy, and use of Developmentally Appropriate Practices (DAP) within their classrooms. Four…

Patterns of quality among approximately 1,400 center classrooms and 350 family child care homes based on measures of global quality, sensitive caregiving, and frequency of language/literacy and math/numeracy activities were examined. Four patterns of quality were identified. Provider education was predictive of higher quality care in both centers…

In December 2014, then Secretary of Education Arnie Duncan announced that $226 million had been awarded to 18 states under the Preschool Development Grants (PDG) program. Duncan said that expanding access to high quality preschool programs was critically important, and that the states receiving funding would serve as a model for others. The goal…

This is the second in a series of policy notes and related publications exploring prospects for developing indicators of teaching quality. The first examined federal databases that include information about teachers, demonstrating that almost none of the measures in these datasets provides indication of teaching quality. This policy note takes the…

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…

Specialized preschool programs can enhance the development of vulnerable young children at risk of special educational needs (SEN). Less is known about the potential of early childhood education and care (ECEC) provided for the general population. This study includes 2,857 children attending 141 ECEC centres in England and 310 with no ECEC. ECEC…

The purpose of this study was to examine whether kindergartens and childcare centres differ in terms of educational and caregiving components. More specifically, two aspects of the process quality of the early childhood education and care were examined regarding the "Activities" and the "Programme Structure." A multi-stage…

Attending high-quality early childhood care and education (ECCE) is associated with higher cognitive and social-emotional skills, especially for children growing up in poverty, but access to high-quality ECCE is limited. This study capitalizes on the random assignment design of the Head Start Impact Study to better understand whether the…

The purpose of this study was to evaluate the overall effectiveness of a three-tier model of positive behavior interventions and supports (PBIS), which was developed and tested in Head Start (HS) programs. Ten HS classrooms from five HS programs participated in the current study. Results indicated that PBIS was effective in improving classroom…

Educators increasingly need to evaluate schoolwide reform efforts; however, complex program evaluations often are not feasible in schools. Through a case example, we provide a heuristic for program evaluation that is easily replicated in schools. Criterion-referenced interpretations of schoolwide screening data were used to evaluate outcomes…

The purpose of the 2012-2013 North Carolina Pre-Kindergarten (NC Pre-K) Evaluation study was to examine the quality of the program and the outcomes for children, along with comparisons to previous years. The primary research questions addressed by this evaluation included: (1) What were the key characteristics of the local NC Pre-K programs?; (2)…

The physical environment of the preschool programmes has been proven to affect both children's overall development and the quality of the programme. However, both nationally and internationally the contribution of the physical environment in the effectiveness of a programme and in the achievement of educational goals is often overlooked. The aim…

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…

Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…

This the executive summary of the 2013-2014 study which provided the baseline year for the longitudinal study. The study included observations of teaching practices in a random sample of 199 Georgia's Pre-K classrooms and assessments of the language, literacy, math, general knowledge, and behavior skills of a sample of 1,169 children attending…
