This memorandum provides information on Advanced Placement (AP) and International Baccalaureate (IB) course enrollment, exam participation, and exam performance during the 2023-2024 school year. During the 2023-2024 school year, 136 AP or IB courses were offered across high schools. Among the 25 comprehensive high schools, all offered AP courses,…

Longitudinal studies can produce biased estimates of learning if children miss tests. In an application to summer learning, we illustrate how missing test scores can create an illusion of large summer learning gaps when true gaps are close to zero. We demonstrate two methods that reduce bias by exploiting the correlations between missing and…

Analysis of consistent Zearn Math users and a comparable group of non-users in a large Southern district shows that students who used Zearn Math had higher levels of academic growth than similar students with no usage. This analysis used the quasi-experimental method, Coarsened Exact Matching (CEM), to examine the impact of Zearn Math across 1,111…

Like most other states, Missouri uses assessments intended to measure whether students are on a pathway to "college and career readiness." The state longitudinal data system now has the capacity to directly test that claim. We make use of 8th-grade assessment (MAP) scores in Math, Science, and Communication Arts for roughly 260,000…

We use administrative panel data from seven states covering nearly 3 million students to document and explore variation in "academic mobility," a term we use to describe the extent to which students' ranks in the distribution of academic performance change during their public schooling careers. On average, we show that student ranks are…

The pivotal role of Algebra in the educational trajectories of U.S. students continues to motivate controversial, high-profile policies focused on when students access the course, their classroom peers, and how the course is taught. This random-assignment partnership study examines an innovative district-level reform--the Algebra I…

This resource provides data on the use of assessment instruments and uniform cut scores. The cut scores presented in this resource are the lowest scores a student can receive on an assessment to be considered college-ready. An asterisk indicates that the state uses a subject area test score for the SAT. "SAT (new)" refers to scores…

Analysis of consistent Zearn Math users and a comparable group of low- or non-users, across 6 districts in Nebraska, shows that students who used Zearn Math consistently had higher levels of academic growth than similar students with low- or no-usage. For this analysis, 784 students who completed an average of 3+ Zearn Math lessons per week,…

The goal of "The 123s" is to present the increasingly large body of private school choice research in a clear and easy-to-read format and cite the relevant studies so that anyone who is interested in the individual results can easily find them and read in more detail. This report is divided into 11 sections. First it summarizes the…

The main aim of this research was to investigate the impact of reducing the number of components on overall performance in GCSE subjects. In particular, researchers were interested in how the grade achieved by candidates on a reduced number of components compares to their grade on the full qualification. This research mainly looked at GCSEs with…

Developmental education assessment and placement policies guide how students may demonstrate college readiness and are placed into college-level courses. States and postsecondary systems use a variety of measures to determine a student's college readiness. Often, policies require that students submit scores from a national, standardized test. Some…

To ensure each county board of education provides a thorough and efficient education for its students, the West Virginia Board of Education (WVBE) annually reviews county scorecards and efficiency profiles provided by the Office of Support & Accountability. County status is reviewed and determined based on multiple measures of student…

Four-day school weeks have proliferated across the United States in recent years, reaching over 650 public school districts in 24 states as of 2019, but little is known about their implementation and there is no consensus on their effects on students. This study uses district level panel data from Oklahoma and a difference-in-differences research…

Many schools and districts administer ACT® Aspire® to measure progress towards college and career readiness. A recent study suggests that ACT Aspire scores can also be used to help identify students who are academically prepared and may benefit from some of the more rigorous courses offered in high schools across the nation, including Advanced…

The current study was a retrospective mixed-methods quasi-experimental design (QED) study to determine the effects of Progress Learning on Grades 6-8 mathematics and ELA achievement by comparison growth on the Georgia Milestones Mathematics and ELA assessments of students who received Progress Learning services, in relation to students that did…
