Recent work examining science test performance in the earliest grades of school has demonstrated that science test score gaps by race/ethnicity are apparent as early as kindergarten and that, in a number of cases, the racial/ethnic test score gaps in science are significantly larger than the corresponding gaps in reading or mathematics. This study…

I use standardized test scores from roughly 45 million students to describe the temporal structure of educational opportunity in over 11,000 school districts--almost every district in the US. For each school district, I construct two measures: the average academic performance of students in grade 3 and the within-cohort growth in test scores from…

The issue of over or under representation of ethnic minority students in special education placement has received a great deal of attention in recent years. An equally important question that has not received as much attention centers on the impact of special education placement, particularly early in a child's education career, on subsequent…

This report provides a summary of the Home Instruction of Parents with Preschool Youngsters (HIPPY) program activities and its effectiveness for Houston Independent School District (HISD) student participants. A total of 637 three to five-year children, along with their parents, participated in the HISD HIPPY program during the 2015-2016 academic…

Black-white test score gaps form in early childhood and widen over elementary school. Sociologists have debated the roles that socioeconomic status (SES) and school quality play in explaining these patterns. In this study, I replicate and extend past research using new nationally representative data from the Early Childhood Longitudinal…

This longitudinal study examined the outcomes of Project Excite on reducing minority students' achievement gaps in STEM over 14 years. Project Excite was designed to provide intensive supplemental enrichment and accelerated programming for high-potential, underrepresented minority students from third through eighth grades to better prepare them…

This report is intended to provide a snapshot of the children in the ECLS-K:2011 cohort who were in kindergarten for the first time in the 2010-11 school year and advanced to first grade in the following year. Information is presented on selected child and family characteristics, such as poverty status and parental education (table 1), obtained…

Analyzing Early Childhood Longitudinal Survey--Kindergarten (ECLS-K) data, we examine how exposure to instructional practices influences math test scores at the end of kindergarten for children from different racial/ethnic and socioeconomic backgrounds, and for children with different levels of math skills at kindergarten entry. We also analyze…

In 2013-14, Letterland had strong implementation, with moderate to high fidelity within approximately 90% of Wake County Public School System (WCPSS) K-1 classrooms. The impact of Letterland on students' reading achievement was neutral to positive. A significantly higher percentage of WCPSS kindergarten students were at or above benchmark mid-year…

This paper examines the effect of exposure to violent crime on students' standardized test performance among a sample of students in New York City public schools. To identify the effect of exposure to community violence on children's test scores, we compare students exposed to an incident of violent crime on their own blockface in the week prior…

This study examined whether fine motor skills were related to the initial scores and growth rate of mathematics achievement in American kindergartners and first graders. Participants were 244 East Asian American and 9,816 European American children from the US-based Early Childhood Longitudinal Study (ECLS-K). To control sampling bias, two…

The Reading, Engaging, and Learning project (REAL) investigated whether a classroom intervention that enhanced young children's experience with informational books would increase reading achievement and engagement. Participants attended schools serving low income neighborhoods with 86% African American enrollment. The longitudinal study spanned…
