Evidence from the Four-Day School Week
Summary
School districts have adopted the four-day school week to curb budget deficits, particularly in rural regions like Colorado and Wyoming, with around 10 districts in California following suit by 2011. This schedule change raises questions about its impact on academic performance. Longer class periods allow varied teaching methods and teacher planning, possibly improving student morale and behavior. Yet, concerns arise about teacher stress, student retention, and increased fatigue, especially for younger students. Evaluating this shift rigorously is vital, but few studies exist. Using a difference-in-differences regression and data from Colorado’s CSAP, researchers analyzed 4th-grade reading and 5th-grade math scores in districts that switched to a four-day week against those on standard schedules. Over a third of Colorado districts adopted this schedule. The results showed a significant increase in math scores post-switch, and while reading scores also rose, the change wasn’t statistically significant. The findings suggest no harm to student performance and even hint at improved attendance rates, though they apply primarily to smaller, rural districts, warranting caution in applying these findings more broadly.
