Resources to educate teachers, parents, and students regarding the four-day school week.
We're glad you're here! This site is a helpful resource designed to educate and share all topics regarding the four-day school week.
Beginning July 1, 2026, "any district located wholly or partially in a charter county or in a city with 30,000 or more population must have:
1,044 hours AND 169 days, or
A 4-day school week approved by voters with at least 142 days.
A financial incentive will be paid to any district that offers a least 169 instructional days.

4-day school week for 2024-2025
*Due to incomplete data and lack of a definition of "4 day week"--the DESE list and our list differ on the list of schools using a 4 day week calendar--consider both lists a "guestimate." Some school districts have chosen to no longer identify as 4 day week districts, although they are on 4 day weeks most weeks. In addition, some schools listed on the historic DESE list as being on the 4 day week were never on the 4 day week (like Union Star and and Gilman City). The research team at Missouri State University continues to define the 4 day week as districts that are on a 4 day school week at least 75% of the school year. To our knowledge, only two districts (Lexington in 2014 and Lutie in 2023) were on the 4 day week and returned to a traditional 5 day week. One district, Stet R-XV, that was on the 4 day week was closed when consolidated into another school district.

We're always interested in bringing together the leading researchers on the four-day school week with school leaders in four-day school week districts. Here are some of our interviews with researchers investigating the four-day school week in the United States.
This interview features Dr. Paul Thompson, Oregon State University---Four-Day Week Impact on Academics with Dr. Gregg Klinginsmith of Warren County Schools, Dr. Mike Henry of Marshfield Schools, and Dr. Jon Turner from Missouri State University. November 29, 2023.
This interview features Dr. Emily Morton, American Institute of Research--Four-Day Week Research Summary with Dr. Sarah Wisdom of New Bloomfield Schools, Dr. Sandy Stegall of Clinton County Schools, and Dr. Jon Turner from Missouri State University. November 2, 2023.
This interview features Dr. Emily Tomayko from Montana State University--The Health Impacts of the Four-day School Week. With Dr. Allison Murphy-Pope from Hurley Schools, Dr. Dustin Storm from Miller Schools, and Dr. Jon Turner from Missouri State University. December 7, 2023.
Dr. Karl Janson from Cabool Schools was one of the first to adopt the four-day school week in Missouri. Now with over 1/3rd of Missouri schools on the four-day week and with Dr. Janson's upcoming retirement, I recorded this interview with Karl to seek his advice about the four-day school week for those considering it. Dr. Janson will retired in June, 2025 but he can still be reached at KJanson70@gmail.com if you have questions or would like to have him speak with your leadership team.
