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.

In this blog, Elizabeth Barker shares the motivation and key insights from her study with Angela Johnson exploring academic achievement and growth for students in special education during summers and school years.

New research using data from over 2,300 rural schools across the US provides unique insight into math and reading achievement of students in rural schools so educators and policymakers can better understand and support the potential needs of rural schools.

Students with disabilities lose even more ground than peers during summer and other interruptions in their learning—but they don’t need to. Data point to a need for services that extend beyond the school year.

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, Learning during COVID-19: An update on student achievement and growth at the start of the 2021-22 school year. We investigated two research questions:

1. How does student achievement in fall 2021 compare to pre-pandemic levels (namely fall 2019)?
2. How did academic gains between fall 2019 and fall 2021 compare to normative growth expectations?
