"Excellence gaps" are the disparities in advanced academic performance that exist between student groups. These gaps have important implications for both academic equity and American economic competitiveness, as the most lucrative jobs often go to those who perform at the highest levels. Although considerable work has evaluated how and…

The purpose of this quantitative ex post facto study was to determine if, and to what extent, differences existed in pre-and-post math scores following the VMath intervention for Title I 6th, 7th, and 8th graders in the Southwestern United States. Three research questions guided this study: (1) is there a statistically significant difference in…

The National Assessment of Educational Progress (NAEP) program only reports state-level subgroup results if it samples at least 62 students identifying with the subgroup. Since some subgroups constitute small proportions of many states' general student populations, these minority subgroups are seldom sufficiently sampled to meet this sample size…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

The purpose of this technical appendix is to share detailed results and more fully describe the sample and methods used to produce the research brief, "COVID's Impact on Science Achievement: Trends from 2019 through 2024. We investigated three main research questions in this brief: 1) How did science achievement in 2021 and 2024 compare to…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

The role of politicians is integral within the public school system. Politician influence directly the policies that impact student achievement. The impact could be based on ideologies. These ideologies could influence a significant difference in Black student achievement. In preparing for this study, the researcher was unable to find…

Research shows a math achievement gap for at-risk and economically-disadvantaged students in the United States. To address this issue, a Texas school district implemented a 90-minute math block-scheduling program with 8th grade students. Shaped by the academic learning time and social justice theories, the purpose of this quantitative program…

As federal mandates continue to emphasize the use of standardized tests, academic research is needed to determine if reading intervention programs are helping to close the achievement gap between struggling readers and their grade level peers. Although previous research indicated that reading intervention can be an effective tool for increasing…

Utilizing the National Assessment of Educational Progress (NAEP) data, this study examined (1) how fourth and eighth-grade ELLs' mathematics and reading scores on national tests compared to their non-ELL peers' scores over the testing period between 2003 and 2011, and (2) if gender and ethnicity contributed to variation in the growth patterns…

This year's Brown Center Report (BCR) on American Education is the 17th issue overall since its beginning in 2000. The 2018 edition focuses on the state of social studies and civics education in U.S. schools. Like previous editions, which were authored by Tom Loveless, the report comprises three studies: The first chapter examines student…

Federal regulations indicate that the achievement gap must be closed between subgroups, including the gap between special education and non-special education students. We explored the ways in which achievement trends are influenced by three methods of reporting (cross-sectional, cohort-static, and cohort-dynamic). We also investigated (a) the ways…

Purpose: The purpose of this quantitative, experimental study was to determine if there was a significant difference in 2016 Smarter Balanced Assessment (SBA) English language arts (ELA) writing levels and ELA overall achievement levels between 7th- and 8th-grade students with and without access to Chromebooks for at least one 46-minute period of…

Assessing the achievement of students in elementary and secondary schools and the nation's educational progress is fundamental to informing education policy approaches. Congressional interest in this area includes and extends beyond the annual assessments administered by states to comply with the educational accountability requirements of Title…

Brief, targeted self-affirmation writing exercises have recently been offered as a way to reduce racial achievement gaps, but evidence about their effects in educational settings is mixed, leaving ambiguity about the likely benefits of these strategies if implemented broadly. A key limitation in interpreting these mixed results is that they come…
