Through a synthesis of test publisher norms and national longitudinal data sets, this study provides new national norms of academic growth in K-12 reading and math to help reinterpret conventional effect sizes in time units. We propose "d'," a time-indexed-effect-size metric to estimate how long it would take for an "untreated"…

The purpose of this study was to proffer the idea to "gaze" past gender and racial achievement gaps by providing a growth-based assessment of the achievement of Black girls. The study aims to elucidate how alternatives to traditional achievement gap analyses can yield information relevant to addressing classroom challenges. This…

Using National Assessment of Educational Progress data from 2003 to 2015, this brief describes changes in the reading and mathematics performance of multilingual students--defined as students who report a primary home language or languages other than English. Although all students' scores improved, multilingual students' scores improved two to…

In this chapter, we review two approaches for understanding these national differences in math abilities. The first approach attempts to link cross-national differences in educational input to cross-national differences in test scores. A tacit assumption of this approach is that children's performance on tests of mathematics is a direct effect of…

This study makes use of data from NCES's High School Longitudinal Study of 2009 to ascertain the relationship of number of mathematics courses and content of mathematics courses to mathematics achievement. As one contribution, the study replicates a process to quantify mathematics course content. Results of the study show that mathematics content…

This study builds on a 2019 Fordham Institute report that examined the relationship between charter school enrollment share--the share of students in a community who enroll in a charter school--and the average achievement of all the students in that community, including those in traditional public schools. Like its predecessor, this report seeks…

Research to date on the effects of between-school tracking on inequalities in achievement and on performance has been inconclusive. A possible explanation is that different studies used different data, focused on different domains, and employed different measures of inequality. To address this issue, we used all accumulated data collected in the…

This is the technical appendix for the report "Gaining Momentum: Refining Corequisite Learning Support to Boost Student Success in the First Year and Beyond" which seeks to develop a body of actionable information about how to refine learning support, close equity gaps, and promote strong momentum toward success for community college…

This study reports achievement levels and fall-to-spring gains in grades K to 8 for three groups of English Learners (ELs): (a) ever-ELs who were ever eligible for service; (b) current-ELs who continue to require service; and (b) dually-identified students eligible for both EL and Special Education services. I leverage unique data that include…

Poverty has been identified as a barrier for at-risk student achievement across America. Can personalized competence-based learning provide at-risk students the skills and knowledge needed to close the achievement gap on the state assessment in Mathematics and English Language Arts/Literacy (ELA) for students after a two-year treatment? The…

As Taiwanese students progress from elementary to junior high school, there is a remarkable increase in the inequality of achievement in mathematics. This increase is of a magnitude not seen in other countries. Findings show that the widening-gap phenomenon is accompanied by an exceptional increase in the percentage of students reaching the…

For the past three academic years, the COVID-19 pandemic disrupted learning and the relationships between teachers, students, families, and communities that are at the heart of education. Even as school buildings reopened to in-person instruction, periodic quarantines, social distancing, and canceled events had a profound impact on students'…

This study explores the effects of school climate on the disparities in students' mathematics achievement, drawing on data from the Programme for International Student Assessment (PISA) 2012 for Shanghai, China. The results of a two-level linear model and quantile regression indicate that three dimensions of school climate (student--teacher…

Students in any grade level vary widely in their mathematics achievement, with the typical classroom including four to seven grade levels of mathematics proficiency. Due to this large range of mathematics learning needs, some schools offer certain courses in earlier grades than is typical. In this study, we analyzed multiple, large, national…

Asian Americans are the most highly educated racial group in the United States and are commonly heralded as the model minority for their high academic success. Nevertheless, previous research suggests that Asian Americans may face certain disadvantages in school settings. For example, Asian Americans' academic advantage over non-Hispanic white…
