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,…

In 2016, the Progressive Policy Institute (PPI) released an analysis of school policies regarding Advanced Placement (AP) credit. Despite being one of the few ways students could seek to graduate in fewer than four years, PPI discovered that the vast majority of the nation's top schools restricted students from applying AP coursework toward degree…

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…

The Monitoring the Future (MTF) study monitors historical and developmental changes in substance use prevalence among key subgroups of the general U.S. adolescent and adult population. The current study first devised and evaluated a cohort-specific pooled analysis weighing procedure for the MTF panel study that weighted back to the initial 12th…

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 purpose of this occasional paper is to compare point estimates and trends included in the Monitoring the Future (MTF) Panel Study annual report: "National Data on Substance Use among Adults Ages 19 to 60, 1976-2021" prepared using historical post-stratification weights, with the same point estimates and trends obtained when using MTF…

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…

Among students in the 2024 ACT-tested graduating class, over 374,000 took the PreACT 8/9® or PreACT test before taking the ACT. This issue brief compares the ACT scores and college enrollment rates for students who took a test from the PreACT Suite of Assessments versus those who did not. The brief also examines average PreACT-to-ACT gain scores…

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…
