Modifies the election date, terms of office, and term limits for members of school boards

HB 539 changes Missouri school board election rules, affecting all public school districts in the state. It mandates that school board elections occur on the first Tuesday after the first Monday in November of even-numbered years starting in 2026, with all members serving two-year terms. The bill also establishes an eight-year cumulative term limit for board members (counting service before 2026) and requires partisan elections beginning in 2026, where candidates must declare party affiliation or run as independents. These changes replace existing election schedules, term lengths, and voting procedures for school boards statewide.
