Trimester School Year Pilot Program; establish.

HB 440 establishes a pilot program to test a trimester school calendar (dividing the school year into three 75-day terms with 15-day breaks) in up to 12 Mississippi public school districts. Participating districts must follow a minimum 225-day school year, implement a new core curriculum for grades 4-12 covering language arts, math, social studies, science, and foreign language, and receive increased state funding. The State Board of Education must select districts to represent diverse sizes, locations, and demographics - including at least one per congressional district - and report results to legislators by January 2028 on whether to adopt the trimester model statewide. This bill directly affects participating school districts and their students in grades 4-12 through mandated calendar and curriculum changes.
