This study uses test scores from 5.4 million U.S. students in Grades 3–8 to track changes in math and reading achievement across the first 2 years of the COVID-19 pandemic.

This study used longitudinal data from a sample of 467 preschoolers to examine (1) if children’s executive function (EF) skills at the beginning of pre-K predict growth in their mathematics achievement across the pre-K year, (2) whether growth in learning behaviors, specifically task orientation, mediate the associations between EF and mathematics achievement, and (3) if there are sex differences in these associations.

Four-day school weeks have proliferated across the United States, but little is known about their implementation or their effects on students. This study uses district-level data from Oklahoma  to provide estimates of the causal effect of the 4-day school week on high school students’ ACT scores, attendance, and disciplinary incidents during school.

This study uses test scores from 4.9 million U.S. students in Grades 3 through 8 to examine the academic disruptions of the COVID-19 pandemic by modeling student achievement trends prior to and during the pandemic, with particular focus on growth in 2020-2021.

This study compared the test taking disengagement of students taking a remotely administered an adaptive interim assessment in spring 2020 with their disengagement on the assessment administered in-school during fall 2019.

This study evaluates the effects of asking items throughout the passage (i.e., embedding items) to achieve a more precise measure of reading comprehension by removing barriers for students to demonstrate their understanding. Results showed a significant impact of embedding comprehension items within reading passages on the measurement of student achievement in comparison to answering items at the end of the passage.

This study investigated teacher adaptation to the changes in teaching conditions caused by the transition to distance learning in the COVID-19 pandemic.
