This study presents estimates of Black-White, Hispanic-White, and income achievement gaps using data from two different types of reading and mathematics assessments: constructed-response assessments that were likely more cognitively demanding and state achievement tests that were likely less cognitively demanding (i.e., composed solely or largely…

Too many talented students who go to under-resourced schools do not achieve their full potential. Though they may perform very well relative to their classmates, these students do not receive the same kinds of academically challenging opportunities throughout their educational journey as do their counterparts in better-resourced public and private…

This study of 952 fifth and sixth graders in Washington, DC, and Alexandria, Virginia, found that students who were offered the "Higher Achievement" program had higher test scores in mathematical problem solving and were more likely to be admitted to and attend private competitive high schools. "Higher Achievement" is a…

Much of the achievement gap between rich and poor students can be attributed to out-of-school factors, yet few schools have a comprehensive, coordinated system for addressing students' nonacademic needs. Within a group of Catholic schools located in one city, this study examined academic achievement on the Stanford Achievement Test battery in…

The Houston Independent School District offers two primary bilingual programs for Spanish-speaking English-language learners (ELLs). In both programs, students may transition into a pre-exit phase of bilingual education so long as they meet certain performance criteria. In this Pre-Exit phase, predominantly English-language instruction is used in…

The purpose of this study was to determine the reading achievement effects of a school-year-long program of sustained silent reading in a middle school. Students' scores on the Stanford Achievement Test, Ninth Edition across three years (2006, 2007, and 2008) were analyzed to test eleven null hypotheses. A 3 x 3 repeated measures factorial ANOVA…

The Houston Independent School District offered five different bilingual programs for language minority students during the 2012-2013 school year. In the Pre-Exit phase of bilingual education, students transition to a predominantly English-language instruction program in core subject areas. This report summarizes the performance of students who…

This report presents the results of an experiment conducted in Alabama beginning in the 2006/07 school year, to determine the effectiveness of the Alabama Math, Science, and Technology Initiative (AMSTI), which aims to improve mathematics and science achievement in the state's K-12 schools. This study is the first randomized controlled trial…

The purpose of this study is to determine if the practice of classroom looping impacts the academic achievement scores at a Minnesota inner city elementary school. Reading and math academic achievement score comparisons were used based on the Stanford Achievement Test Series 10 (SAT10). Target population consisted of 38 students from looping…

This study explores two approaches to directly measuring the quality of instruction: teachers' assignments with student work and focused lesson observations. The technical quality and potential feasibility of these approaches for measuring instruction in large numbers of classrooms are compared within two different content areas (reading…
