List of Missouri Four-Day School Week Districts With Contact Information-Updated for 2025-2026 (Link)* 

DESE Historical List of Missouri Four-Day Week Schools Update for 2025-2026 (188 school districts)*

*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 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.  At least one district, Stet R-XV, that was on the 4 day week was closed when consolidated into another school district.
