Most accountability policies monitor Head Start quality at the center level by selecting a subset of classrooms within a center to represent quality. This study explores variation in classroom quality in Head Start and implications for accountability systems and children's well-being. We find that one third to one half of the variation in quality…

This study identified patterns of classroom and family experiences and developmental outcomes for young children in segregated early education. This study is based on data from a high-quality early education program serving young children from low-income households in 19 schools across the U.S. The sample included 1,521 children during the…

This article synthesizes findings from a reanalysis of data from the Head Start Impact Study with a focus on impact variation. This study addressed whether the size of Head Start's impacts on children's access to center-based and high-quality care and their school readiness skills varied by child characteristics, geographic location, and the…

Research Findings: Early care and education (ECE) quality is critical for children's learning, and ECE programs' support of teachers' learning may be important for ensuring high-quality classrooms. Yet little is known about how such supports operate outside of resource-intensive research studies and interventions. This study explores pathways…

As part of President Obama's Early Education Plan, Congress authorized $500 million in the 2014 Omnibus Act to support states and communities in expanding high-quality early learning through the creation of a new Early Head Start-Child Care Partnership initiative. This initiative has placed renewed interest on research regarding the nature and…

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…

Research suggests that attending high quality, formal early childhood education (ECE) is associated with stronger cognitive and social-emotional skills, especially for low-income children. Yet at current funding levels, federally-funded programs like Head Start cannot serve all eligible children. Thus, state-level policies governing the…

Head Start is a national program that promotes school readiness by enhancing the social and cognitive development of children through the provision of educational, health, nutritional, social, and other services to enrolled children and families. The Head Start program provides comprehensive child development services to economically disadvantaged…

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…

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 report includes key information on the Head Start Family and Child Experiences Survey 2014-2018 (FACES 2014) study design and a set of data tables presents descriptive statistics for the characteristics of classrooms, teachers, centers, and programs serving Head Start children and families in spring 2015. Data are drawn from the spring 2015…

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 study seeks to answer the following question: Are impacts on Head Start classroom quality associated with impacts of Head Start on children's learning and development? This study employs a variety of descriptive and quasi-experimental methods to explore the role of classroom quality as a mediator or mechanism of Head Start impacts. This…

This paper investigates the long-term impact of participation in the Chicago School Readiness Project (CSRP) during the Head Start year on children's behavioral outcomes at the end of their Kindergarten year. The primary questions addressed in the paper are: (1) What is the experimental impact of CSRP on two-year change (from Fall Head Start to…

Plans to improve literacy instruction (N = 1,504) developed by teachers and early literacy experts in coaching sessions (N = 280) conducted in 31 Head Start classrooms were examined to describe a general trajectory of coaching with regard to content coverage, pedagogical emphasis (instructional material, teaching behavior), and progression (new,…
