The Matthew Effect is an educational theory that children who begin their academic careers with lower reading scores do not catch up to their peers, instead falling farther and farther behind as their schooling progresses. This study includes a hierarchical multiple-regression analysis of within-year benchmark data for the presence of Matthew…

These are the appendixes for the report, "Trends and Gaps in Reading Achievement across Kindergarten and Grade 1 in Two Illinois School Districts." This study examined reading achievement data for kindergarten and grade 1 students in two districts in Illinois: District U-46 (Elgin Area Schools) and District 186 (Springfield Public…

The purpose of this quasi-experimental quantitative study was to determine whether the supplemental phonics program, Fundations, improved reading skills over time. Ehri's theory of orthographic mapping served as the theoretical framework for this study. Archival data from 254 second grade students who did, or did not, participate in the…

Identifying effective means of ameliorating achievement gaps and addressing literacy deficits is essential. Computer-assisted instruction (CAI) is one avenue for providing this effective instruction to the students that can most benefit from it. In the current study, kindergarten students in a public school district in Illinois received…

Girls tend to do better than boys academically, in part because they are more engaged in school. What if they weren't? Using nationally representative data, I examine how equal starting points and trajectories of behavioral engagement in elementary school could change gender test score gaps. I find that equal engagement patterns could entirely…

Using a national sample of kindergarten to eighth grade students from Catholic and public schools who took MAP Growth assessments, we examine achievement growth over time between sectors. Our findings suggest that while Catholic school students score higher in math and reading than public school students on average, they also enter each school…

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,…

To assess education progress in the early grades and identify achievement gaps, this study examined reading achievement data for kindergarten and grade 1 students in two districts in Illinois: District U-46 (Elgin Area Schools) and District 186 (Springfield Public Schools). Drawing on a different reading assessment in each district, the study team…

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…

Important educational policy decisions, like whether to shorten or extend the school year, often require accurate estimates of how much students learn during the year. Yet, related research relies on a mostly untested assumption: that growth in achievement is linear throughout the entire school year. We examine this assumption using a dataset…
