A new University of Oregon review of 11 studies found little evidence that the four-day school week benefits student academic performance, attendance, behavior or graduation rates.
The HEDCO Institute for Evidence-Based Educational Practice at the UO conducted the systematic review, a rigorous analysis of the highest-quality research available on the four-day school week in the United States.
“Districts often turn to four-day school weeks to address budget and staffing pressures, but the evidence suggests this change may come at a cost to students,” said Elizabeth Day , a research assistant professor at the HEDCO Institute and part of the team that produced the report. “There’s no consistent evidence that moving to a four-day schedule improves learning outcomes — and in some cases, it may do the opposite.”
The four-day school week schedule is a growing trend in U.S. education, with adoption by 2,100 schools in more than 850 school districts. The schedule is more common in rural areas, but an increasing number of suburban and urban districts are considering it.
The HEDCO Institute review findings paint a complex picture, one that differs based on school location (rural vs. non-rural), grade level and student outcome.
Key Findings:
No statistically large positive effects were found for any student outcome in the highest-quality studies.
Rural districts have been studied more rigorously than non-rural districts and no studies included just city schools.
In r ural districts, evidence was mixed and suggested a four-day school week:
In non-rural districts:
For studies combining rural and non-rural districts , most findings were negative :
The HEDCO Institute review highlighted two critical unanswered questions:
How much instructional time is lost or preserved?
Maintaining instructional hours is important for minimizing negative impacts on student achievement. Loss of learning time risks a loss of learning.
What do students do on the fifth day?
Without school, home or community-supported programs, students may lack access to safe, age-appropriate activities — putting their development and well-being at risk. Maintaining activities that foster healthy youth development on the fifth day is important for minimizing other negative impacts.
The review focused exclusively on student outcomes, including:
