In this brief we examine how variability in students' math and reading test scores changed across the pandemic, including whether increased dispersion was concentrated at one part of the test score distribution. Using reading and math assessment data from a sample of 8 million students in grades 3-8 in 24,000 public schools who took MAP Growth…

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, "The Widening Achievement Divide during COVID-19." The authors investigated two main research questions in this brief: (1) To what degree have students' reading and math…

This research uses a descriptive quantitative statistical design to examine campus-level results from the State of Texas Assessments of Academic Readiness (STAAR). The focus is on describing the achievement disparities between campuses that implemented Transitional Bilingual Education (TBE) programs and those implementing Dual Language (DL)…

In this investigation, differences in the reading performance as a function of degree of economic disadvantage for Texas Grade 3 students were examined. Data were obtained from the Texas Education Agency on all Texas Grade 3 students for the 2012-2013, 2013-2014, and 2014-2015 school years. In all analyses, statistically significant differences,…

Remote learning has reduced the mathematical performance of students. Mathematical reasoning is the critical skill that enables students to make use of all other mathematical skills. The aim of the present study was (1) to develop the mathematical reasoning skills of underachieving students and (2) to explore the application options, benefits and…

This brief continues ongoing research by NWEA® examining the degree to which the COVID-19 pandemic, and its associated school closures, influenced student learning. Prior research focused on math and reading and found that the pandemic's negative impact steadily accumulated during the 2020-2021 school year, with significant disparities in…

The academic achievement gap is a persistent and pernicious educational challenge confounded with race and socioeconomic status. The achievement gap persists despite over three decades of interventions and federal, state, and local policies and initiatives meant to close it. We examine the achievement gap in one of the most diverse states in the…

Propensity score matching was used to compare third-grade test scores in English language arts, mathematics, science, and social studies for children who had and had not participated in Georgia's Pre-K 4 years earlier. After matching, each group included 46,262 children (mean age 8.36 years in third grade). In all subject areas, children who had…

The purpose of this study was to determine if there was a difference between a student's reading/language arts TCAP scale score and his or her lunch status for students in grades three, four, and five within two school systems in Tennessee. The population consisted of 2,442 students who were in grades three, four, and five during the 2014-2015…

The goal of HISD [Houston Independent School District] prekindergarten programs is to offer the youngest learners strong foundations built on solid concept, as well as individual and group discovery. The program curriculum focuses on beginning literacy, numeracy, social emotional development as well as supporting the individual linguistic and…

In the first systematic study of gender achievement gaps in U.S. school districts, we estimate male-female test score gaps in math and English Language Arts (ELA) for nearly 10,000 school districts in the U.S. We use state accountability test data from third through eighth grade students in the 2008-09 through 2014-15 school years. The average…

Single-timepoint educational measurement practices are capable of assessing student ability at the time of testing but are not designed to be informative of student capacity for developing in any particular academic domain, despite commonly being used in such a manner. For this reason, such measurement practice systematically underestimates the…

Reading comprehension growth trajectories from 3rd to 7th grade were estimated for 99,919 students on a state reading comprehension assessment. We examined whether differences between students in general education (GE) and groups of students identified as exceptional learners were best characterized as stable, widening, or narrowing. The groups…

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…

Research has suggested the "No Child Left Behind Act" passed in 2001 has resulted in narrowed curriculum and a failed attempt at its primary objective to close the achievement gap. Understanding changes that have occurred in student achievement from 2011 to 2014 of the NCLB requirements is the focus of this quantitative ex-post facto…
