In a recent study of schools in Texas—where nearly 200 districts had adopted the truncated schedule by the 2025-26 school year—Georgia State University economist Cade Lawson found that turnover fell about 2.7 percentage points in districts that moved to four-day weeks over the course of 17 years.
A 2023 report examined one of the first metropolitan districts in the nation to adopt a four-day school week, the Brighton district outside of Denver. It concluded that larger districts that make the change could see a drop in teacher retention, student achievement, and local home values, at least in the short term.
