Four-Day School Week May Boost Math Scores

Shortening the school week to only four days appears to boost elementary school students’ math performance, according to a new study by researchers at Georgia State University and Montana State University.

The study evaluated the impact of a four-day school week on student achievement by comparing fourth-grade reading and fifth-grade math test scores from the Colorado Student Assessment Program (CSAP) to those of students who attended a traditional five-day school week.

The findings showed that a four-day school week had a statistically significant positive impact on math scores for fifth-grade students. Reading scores were not affected.

The study suggests there is little evidence that moving to a four-day week would harm student academic achievement, an important finding for U.S. school districts seeking ways to cut costs without hindering learning.

“What interested me about our results is they were completely opposite to what we anticipated,” said Mary Beth Walker, Ph.D., dean of the Andrew Young School of Policy Studies at Georgia State.

“We thought that especially for the younger, elementary school kids, longer days on a shorter school week would hurt their academic performance because their attention spans are shorter. Also, a longer weekend would give them more opportunity to forget what they had learned.”

While the shorter school week did not have a measurable impact on reading outcomes, “the idea that the change in the calendar did not have negative effects we thought was an important result,” Walker said.

Several school districts in the U.S. have transitioned from the traditional Monday through Friday schedule to a four-day week schedule as a cost-saving measure to reduce overhead and transportation costs.

The four-day school week requires school districts to lengthen the school day to meet minimum instructional hour requirements. Until now, however, there was a lack of information on whether the four-day school week affects student performance, Walker said.

The researchers have speculated on why the shortened school week positively affected students but there is not enough data to draw definite conclusions.

“We thought the longer days might give teachers an opportunity to use different kinds of instructional processes,” Walker said. “We also speculated that a four-day school week lowered absenteeism, so students who had dentist’s appointments or events might be able to put those off until Friday and not miss school. We thought there might be less teacher absenteeism.

“My own personal hypothesis is teachers liked it so much — they were so enthusiastic about the four-day week — they did a better job. There’s some evidence in other labor studies that four-day work weeks enhance productivity.”

Walker notes that the findings are only applicable to smaller and more rural school districts. Further studies should be performed to understand the effects on urban school districts, she said.

The research is published in the journal Education, Finance and Policy.
