Ohio would stop allowing for-profit operators to manage its public charter schools in 2023 under a new legislative proposal, aimed at stronger accountability for that sector. The bill also would subject the operators to annual state audits and make public more of the records related to charter schools’ management and operations. Backers say the proposal will remove profit motivation and help level the playing field for public schools. Officials estimate the change would affect more than 175 schools in all. The Ohio Education Association and the Ohio Federation of Teachers support the new proposal.
