This Data Appendix provides the data behind the Fact Sheet, "California's K-12 Test Scores."

Background: Although prior research has explored students' affective experiences in mathematics and its demographic correlatives, additional studies are needed that: (1) use large national data sets; (2) incorporate a broad range of affective constructs; (3) consider trends in student affect over time; and (4) include younger children and…

Extended testing time is a common accommodation given to students with disabilities. However, little is known about whether students who are eligible for the accommodation actually use it, and with what effect. The present study used process data available from the digitally delivered 2017 National Assessment of Educational Progress (NAEP)…

Hispanic literacy development in the Southwestern US is examined through standardized assessment data derived from recent National Assessment of Educational Progress (NAEP) and Texas Academic Performance Reports (TAPR). This longitudinal study focuses on significant variables across a spectrum of grade levels for Hispanics of Mexican descent.…

In Spring 2022, Pioneer Institute published "The Boston Publics Schools' Road to Receivership," which detailed the findings of the 2019 state-commissioned, third-party report evaluating outcomes and operations in the Boston Public Schools (BPS). The report was scathing, citing years of declining enrollment, low test scores, financial…

The purpose of this technical appendix is to more fully describe the sample, methods, and results of the research brief "Boys Regain the Advantage in Middle School STEM Skills: Post-COVID Trends in Gender Achievement Gaps." The authors investigated three research questions in this brief: (1) How have 8th grade gender gaps in STEM…

In 2024, half of California's K-12 students met the state standard in English, while one in three were proficient in math. Post-pandemic learning recovery and longstanding disparities in proficiency rates remain key challenges for the state's public schools. This fact sheet discusses the numbers involved with these achievement gaps.

Background: This empirical study aims to investigate the association between mathematics self-efficacy and mathematics achievement gaps among students in Grades 4, 8, and 12, utilizing data from the 2019 National Assessment of Educational Progress (NAEP). The study also considers student-level (e.g., mathematics self-efficacy, gender,…

This empirical research study investigates the relationship between the utilization of Universal Design (UD) elements and math performance among eighth graders. We analyzed 2017 National Assessment of Educational Progress process data using Poisson Generalized Linear Mixed-Effects Models to examine how the frequency of UD element usage varies…

This study examines the effect of the usage of graphing calculators on Black Females' mathematics achievement on the 12th grade National Assessment of Educational Progress (NAEP). This non-experimental research study will analyze the 2015 NAEP publicly available data set, using the twelfth-grade sample, examining their overall math achievement…

The purpose of this study was to examine if teachers' participation in the educational technology professional development was a significant predictor in the 8th grade students' mathematics achievement on the 2013 National Assessment of Educational Progress (NAEP). This non-experimental study analyzed selected variables from the 2013 NAEP 8th…

This dissertation researched the scope of mathematics achievement disparities in the United States and how these disparities can be minimized through a self-efficacy lens. To answer pertinent research questions with data from the National Assessment of Educational Progress (NAEP) 2019 mathematics assessment in Grades 4, 8, and 12, gap analyses,…

Has the achievement of U.S. students improved over the past half century? Have gaps between racial, ethnic, and socioeconomic groups widened or narrowed? These and similar questions provoke near-constant conversation. But answers are uncertain, partly because research to date has yielded inconsistent findings. In this article, the authors bring…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

The National Assessment Governing Board (the Board) contracted with Pearson to design and implement a review of the achievement level descriptions (ALDs) for National Assessment of Educational Progress (NAEP) Grade 8 assessments in Science, U.S. History, and Civics. This document describes the procedural and technical aspects and outcomes of the…
