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 research uses interim assessment test results to measure the impact of prior year attendance on starting achievement the following year. Results show the impacts are significant and persistent.

Does entering school older give students an edge? New research suggests an early advantage may fade in later grades.

This study presents a framework that uses academic trajectories in the middle grades for identifying students in need of intervention and providing targeted support.

In this interview, James Soland discusses his research exploring the connection between social-emotional learning and growth in achievement for English language learner students.

In this study, we examine the impact of two techniques to account for test disengagement—(a) removing unengaged test takers from the sample and (b) adjusting test scores to remove rapidly guessed items—on estimates of school contributions to student growth, achievement gaps, and summer learning loss.

Schools are increasingly held accountable for their contributions to students’ academic growth in math and reading. Under The Every Student Succeeds Act, most states are estimating how much schools improve student achievement over time and using those growth metrics to identify the bottom 5% of schools for remediation.
