The No Child Left Behind Act of 2001 (NCLB) had mixed effects on the nation's educational ecosystem. NCLB succeeded in shifting the focus from inputs to outcomes, shining a light on performance of different student subgroups, and using reporting requirements to spur development of more-robust education data systems. But NCLB included several…

The purpose of this study was to estimate the longitudinal and reciprocal predictive relations between children's social skills, measured by an adaptation of the frequently used Social Skills Rating Scale, and their standardized academic achievement. A large nationally representative sample of elementary school students were assessed at least…

There were 42 Teach for America (TFA) members who had student schedules in both the October 2022 and February 2023 periods. Of those, 33 teachers instructed grades and subjects where students participated in the statewide assessment. The goal of this Research Brief is to estimate the instructional effectiveness of the TFA members in 2022-2023 as…

Girls tend to do better than boys academically, in part because they are more engaged in school. What if they weren't? Using nationally representative data, I examine how equal starting points and trajectories of behavioral engagement in elementary school could change gender test score gaps. I find that equal engagement patterns could entirely…

Under the Individuals with Disabilities Education Act, schools are required to provide a free appropriate public education to students with disabilities and show that the students are making academic progress. This study compares within- and across-years academic growth from kindergarten to 4th grade for students who were ever in special education…

Important educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire school year. We examine this assumption using a dataset…

The Mississippi State Department of Education (MDE) adopted a state assessment in 2014 to measure early literacy skills for incoming kindergarten students (Mississippi Joint Legislature Committee on Performance Evaluation and Expenditure Review [PEER], 2015). The purpose of this study was to determine the effects of early childhood education (ECE)…

The Office of English Language Acquisition (OELA) has synthesized key data on English learners (ELs) into two-page sheets on a variety of subjects. This fact sheet provides the following data on ELs in the United States over the 2017-2018 school year: (1) Percentage of Students Enrolled in K-12 Who Are English Learners; (2) English Language…

The engage2learn approach to educator support provides an in-person and virtual coaching system that builds capacity and engagement in public schools. Engage2learn hired LXD Research to conduct an independent evaluation and analysis of NWEA Math and Reading data collected during the 2021-2022 school year. The goal was to measure how engage2learn…

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…

The effects of instructing kindergarten students (five-year-old in their first year of public school) on patterning were tested. Up to nine students in each class were randomly assigned to three groups in each of six classes, i.e., as many as three from a class in each group. One group received instruction on complex patterns similar to those…

The impact of the COVID-19 pandemic continues to overwhelm the functioning and outcomes of educational systems throughout the nation. The public education system is under particular scrutiny given that students, families, and educators are under considerable stress to maintain academic progress. Since the beginning of the crisis, school-systems…

Throughout the country, state assessments in reading, mathematics, and science continue to play important roles in instructional improvement and accountability. State assessments must align to academic standards that are significantly more challenging than previous standards, reflecting the current knowledge and skill demands of postsecondary…

This Study Snapshot highlights key findings from a study that examines full-day kindergarten (FDK) implementation in Oregon. The evidence base on FDK is generally positive for short-term effects and unclear for longer-term effects, with some prior research associating FDK with gains in student outcomes such as grade 3 math and reading standardized…

Thousands of U.S. school districts and many international schools use MAP® Growth™ to monitor the academic growth of their students and to inform instruction. The MAP Growth assessment is untimed, meaning that limits are not placed on how much time a student has to respond to the items. However, to help schools understand the amount of time MAP…
