This study addressed the issue of low reading proficiency in Kentucky's students with disabilities, potentially exacerbated by post-third-grade curriculum changes. This quasi-experimental ex post facto comparative study aims to determine differences in the grade four reading achievement gap in students with disabilities compared to students…

A variety of databases were used to answer questions about charter and public schools with regard low-income students, special education students, and academic performance. Charter schools in Dallas and Detroit served comparable numbers of poor children, but charter schools enrolled far fewer students in special education.…

This quantitative, causal-comparative research study investigated whether school configuration has an impact on the reading performance of sixth-grade students by comparing the End-of-Grade (EOG) reading assessment Grade Level Proficiency (GLP) scores of sixth-grade students in K-8 configured schools to sixth-grade students enrolled in 6-8 grade…

This study examined the effect of small class size intervention on student outcomes using reading achievement scores as measured by the Comprehensive Test of Basic Skills (CTBS), a standardized, norm-referenced test, while controlling for independent variables inclusive of students' gender, race, socioeconomic status (SES), and environment. This…

The long-term impact of prekindergarten programs is an important consideration given the trend of dedicating more resources to these programs. However, long-term impact of prekindergarten programs is not well-understood and recent studies have shown preschool effectiveness can vary across states and programs. A state run prekindergarten program in…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

Newsela contracted with LearnPlatform by Instructure (LearnPlatform), a third-party edtech research company, to examine the relationship between Newsela ELA usage and outcomes for students. LearnPlatform designed the study to satisfy Level II requirements (Moderate Evidence) according to the Every Student Succeeds Act (ESSA). The study included…

The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the proficiency standards that states set for their students. Since standards vary across states, the results of the various state assessments cannot be used to directly compare…

Despite ongoing efforts to reform schools, the longstanding racial/ethnic achievement gap still persists, particularly for boys of color; in many cases, the gap is widening, particularly for students transitioning from elementary to middle school. The focus of this study was to examine the impact of effective instructional practices for struggling…

This study investigates the academic outcomes of a special education student cohort in the state of Indiana placed in high and low inclusion settings. Student scores in these two settings from the Indiana State Test of Educational Progress (ISTEP+ English/Language Arts and math) were compared from fourth grade in 2014 through the eighth grade in…

In this brief we examine how variability in students' math and reading test scores changed across the pandemic, including whether increased dispersion was concentrated at one part of the test score distribution. Using reading and math assessment data from a sample of 8 million students in grades 3-8 in 24,000 public schools who took MAP Growth…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

The purpose of this study was to determine if Appreciative Inquiry affects assessment scores of middle school students, grades 6-8. The data used in this study was collected from a cohort of students impacted by the COVID-19 pandemic school shutdowns with inconsistent return to structured, continuous in school routines. The data used in this study…

The purpose of this study was to study the impact on student performance due to participation in the Catapult Learning Intervention program in the Mathematics and Reading services offered in a religious non-public school system in the Northeastern United States from grades 6-8. Student scaled scores from the NWEA MAP assessments administered at…

This study identifies students' academic trajectories in the middle grades relative to a set of college readiness benchmarks. We apply math and reading college readiness benchmarks to rich longitudinal data for more than 360,000 students across the nation. Student-level and school-level demographic characteristics significantly predict academic…
