Ascent Classical Academy Charter Schools — the governing board over charter schools serving nearly 2,000 students in Lone Tree, Brighton, Windsor and Grand Junction — terminated its contract early with management organization Ascent Classical Academies, which is a Golden-based nonprofit with a similar name that establishes and operates charter schools. Both the governing board and parents say the schools have faced multiple challenges with ACA over the past six years since their first school began operating in Lone Tree, including high turnover among school leaders and teachers and debates over what curriculum to use. The board in September unanimously voted to end its contract with ACA on June 30, 2024, “contingent upon continued cooperation by ACA,” minutes from a Sept. 26 board meeting show. Rob Williams, the charter school network’s temporary president who has long served as the board chair and treasurer, told The Colorado Sun that the board decided to sever ties sooner.
