Modifies provisions governing accountability measures for elementary and secondary schools

HB 2539 requires all Missouri public school districts, schools, and charter schools to publish standardized annual report cards online by specific deadlines, detailing student performance, finances, and staff data to meet federal requirements. It establishes a new A-F rating system based on student achievement (40% for K-8, 25% for high schools), academic growth metrics, and for high schools, a "Success Ready Graduate" measure tracking college credits, career credentials, or advanced exams. Top-performing schools in the top 5% for performance or growth receive performance-based funding ($100/student) starting after the 2026-27 assessments, with funds used for staff bonuses. The bill directly affects schools, parents, and taxpayers through transparent accountability measures and ties funding to specific, measurable outcomes.
