Authorizes the establishment of a charter school in any school district

HB 2420 authorizes charter schools in specific Missouri school districts under defined conditions, directly affecting districts classified as unaccredited, provisionally accredited, or meeting population size criteria. The bill establishes six eligibility scenarios for charter schools, including districts with financial hardship or those in counties with 150,000-200,000 residents, while limiting local school board sponsorship to districts with under 1,550 students or allowing broader sponsorship in certain cases. It permits eligible sponsors like local school boards, colleges, or nonprofits to operate charter schools, and imposes a 35% enrollment cap on charter schools within large districts (over 1,550 students). The law also prohibits sponsors from charging fees for charter applications and outlines transition rules for districts changing accreditation status.
