Math achievement plays a pivotal role in students' success in school and beyond. Algebra, in particular, serves as a crucial gateway: it increases the chances a student takes advanced math in high school, which has implications for their college and career prospects. In 2023 and 2024, the American Mathematics Educator Study (AMES) surveyed…

In this study, the authors highlight the differences in classroom-, teacher-, and school-level factors in 8th and 9th grade algebra experiences along socioeconomic and racial/ethnic lines using nationally representative survey data from the American Mathematics Educator Study. Several takeaways emerge from this analysis. The analysis shows that…

Debates about grade retention weigh the academic benefits of remediation against its social and psychological costs. Louisiana adopted a retention policy aimed at capturing these benefits while mitigating the harm. It used test score thresholds to distinguish between retention in grade 8, promotion to grade 9, and a grade "8.5" where…

In this study, we highlight the differences in classroom-, teacher-, and school-level factors in 8th and 9th grade algebra experiences along socioeconomic and racial/ethnic lines using nationally representative survey data from the American Mathematics Educator Study. Several takeaways emerge from our analysis. First, we show that highest-poverty…

Though schools do not track in Brazil, I find that black/white classroom segregation in Brazil is greater than recent estimates from North Carolina high schools (Clotfelter et al., 2020). How does race-based classroom segregation occur without tracking, and in a supposed "racial paradise," no less? Using national, student-level data…

Special education is an approach to schooling that draws significant critique.

Employing data from the Toronto…

Large scale assessment is conducted at different class levels for various purposes such as identifying student success in education, observing the impacts of educational reforms on student achievement, assessment, selection, and placement. It is expected that these tests and their items are used in education do not display different traits with…

Students classified as English learners (EL) are a protected class of students with core legal rights. There are clear opportunities to strengthen education policies and practices to improve opportunities and outcomes for EL-classified students. This dissertation is comprised of three studies examining key issues in EL education with the goal of…

Education leaders in Virginia use early access to Algebra I as one method to provide students more time to take college preparatory courses in high school, thereby increasing students' likelihood of graduating prepared for college and careers. Yet, little data are available for these leaders to examine whether their approach is warranted. Members…

This document provides the two appendixes that accompany the full report, "Algebra I and College Preparatory Diploma Outcomes among Virginia Students Who Completed Algebra I in Grades 7-9." Appendix A, "Methods," details the data sources, study population, and analysis methods used in the study. Appendix B, "Supporting…

Education leaders in Virginia use early access to Algebra I as one method to increase students' likelihood of graduating from high school prepared for college and careers. This study used administrative data to calculate descriptive statistics on Algebra I outcomes and attainment of college preparatory diplomas among students by their grade 5 math…

Using an integrated administrative data set, out-of-home residential placements (i.e., child welfare, juvenile justice, mental health) were examined in a sample of early adolescents in a large urban school district. Out-of-home placements were tracked across Grades 7 to 9 in a population of 58,000 youth. This included 10,911 students identified…

Georgia law mandates that students who fail the state Criterion-Referenced Competency Tests (CRCT) twice in grades three, five, and eight be retained, unless a committee is convened including a subject-area teacher, an administrator, and the student's parent or guardian. If the committee unanimously decides the student may be successful in the…

Exit rates from Limited English Proficiency (LEP) for students who enter the Wake County Public School System (WCPSS) as LEP students vary by when students enter WCPSS (based on students entering in kindergarten, grade 6 or 7, or grade 9). Based on our 2008-09 cohorts, students entering in grades 6 or 7 were most likely to exit LEP status after…

Social promotion is defined as the practice of allowing students who failed to meet performance standards and academic requirements the opportunity to pass on to the next grade with their peers.
