Thinking About a 4-Day School Week? Here’s What the Data Really Says About Test Scores

Thinking About a 4-Day School Week? Here’s What the Data Really Says About Test Scores

Why the Four-Day School Week Keeps Coming Up (Especially in Rural Districts)

As a district leader in special education, I’ve learned that schedule changes are rarely just “calendar decisions.” They’re operational decisions that ripple into instruction, staffing, compliance timelines, and student services. The four-day school week is a prime example. While it first appeared as early as the 1930s, it expanded significantly in the 1970s when districts sought to conserve energy and reduce operating costs. Today, it continues to surface most often in rural communities—places that frequently innovate out of necessity but don’t always receive much attention for it.

Rural districts serve a significant portion of students nationwide. Johnson and Strange (2009) reported that about 19% of U.S. public school students attend school in a rural district. These districts often face long bus routes, limited local tax bases, and persistent staffing shortages—especially for specialized roles like speech-language pathologists, occupational therapists, and school psychologists.

The Big Question: Does a Four-Day Week Hurt Student Achievement?

Paul Hewitt and George Denny’s study, The Four-Day School Week: Impact on Student Academic Performance (Rural Educator, Winter 2011), tackled the question many boards and families ask first: “What happens to test scores?”

The study examined Colorado, where four-day calendars were relatively common (62 districts at the time). Researchers used results from the Colorado Student Assessment Program (CSAP) to compare performance in reading, writing, and mathematics across grades 3 through 10. Importantly, they used a matched-pair design—pairing four-day districts with similar five-day districts based on enrollment size and the percentage of students eligible for free and reduced lunch (a proxy for socioeconomic status).

What the Colorado Data Showed

The results were nuanced and, for many leaders, reassuring:

In practical terms, the study concluded that moving to a four-day week should not be pursued as a strategy to raise test scores. At the same time, the findings suggest that academic performance concerns alone may not be a strong reason to reject a four-day week—especially when districts maintain instructional time by extending the school day.

Seat Time vs. Learning Time: The Quality Question

One of the most important takeaways in the broader discussion is that “more time” does not automatically mean “more learning.” The article references work by Cuban (2008), emphasizing that the real driver is the quality of academic learning time—reducing interruptions, strengthening teacher-student connections, and increasing engaged learning.

This matters because four-day models typically keep total instructional hours similar by lengthening the four days students attend. In Colorado, four-day schedules often used four 7.5-hour days to approximate a traditional five-day week’s total time. Some models can even exceed the five-day total minutes.

Why Rural Districts Consider the Four-Day Week Anyway

In my experience, districts rarely bring forward a four-day proposal because they think it will magically improve academics. They bring it forward because of operational realities. The literature review in the study highlights several recurring motivations:

1) Financial Savings (But Often Modest)

Cost savings—especially transportation and utilities—are the most common driver. Some districts reported substantial savings (for example, one Minnesota district reported an 18% operating savings), while others reported savings closer to 1–2% of the operating budget. The key variable is whether buildings truly close on the fifth day or remain open for activities, tutoring, meetings, or athletics.

From a leadership standpoint, this is where boards can get surprised. If the community expects major budget relief but the district continues operating many functions on the “off” day, the savings may not match the narrative.

2) Attendance, Discipline, and Activities

Multiple sources cited in the article report improvements in student and staff attendance, fewer discipline incidents, and increased extracurricular participation. The logic is straightforward: families can schedule appointments on the non-school day, reducing the need for students and staff to miss instruction time. Some districts also report reduced substitute teacher costs.

3) Popularity After Implementation

Public opinion can be skeptical at first. A Gallup poll cited in the article found low initial support nationally, likely due to misunderstandings about how instructional time is preserved. But locally, when districts communicate clearly and implement thoughtfully, support often grows. In some cases, teacher support after implementation was extremely high.

Implementation Details That Matter More Than People Expect

When districts consider a four-day week, the calendar mechanics are only the beginning. The study and related literature point to decisions that can determine whether the change is manageable or chaotic:

Special Education and Related Services: The “Hidden” Scheduling Impact

This is the area that can make or break the experience for students with IEPs. A four-day week changes the service-delivery puzzle. Even if total minutes remain equivalent, the weekly rhythm shifts—especially for students who benefit from consistent practice and shorter, more frequent sessions.

Key considerations I advise teams to address early include:

Where Online Therapy Can Fit (Especially for Rural Districts)

For districts navigating schedule shifts and persistent related-service vacancies, online therapy can be a practical lever. When implemented well, teletherapy can:

At TinyEYE, this is the space we know best—helping districts maintain continuity of services and compliance even when the calendar and staffing realities are challenging.

Bottom Line: Don’t Choose a Four-Day Week for Test Scores

Hewitt and Denny’s Colorado analysis offers a grounded conclusion: a four-day week is not a proven strategy to increase academic performance. In most comparisons, five-day districts scored slightly higher, but differences were generally small and rarely statistically significant (with the notable exception of elementary writing).

For district leaders, the decision should be framed around operational goals (cost control, attendance, recruitment/retention, community preference) and accompanied by a careful plan to protect instructional quality and student supports—especially special education and related services.
