The Detroit Public Schools is moving ahead with its controversial 2012 Renaissance Plan. That’s Emergency Financial Manager Robert Bobb’s plan to turn up to 50 current schools into charters, rather than closing them down. Bobb says 18 organizations have submitted bids to transform some district schools into charters. He says it’s still unclear how many schools will turn into charters this year or next year. But he’s hopeful some operators will be able to move quickly. “All of the proposals that were submitted are proposals by charter operators who, if successful over the next several months as we go through the evaluation, can open and operate a number of schools this fall.” Bobb stresses the charter operators still need to go through a “rigorous” evaluation process. He says he plans to have a final charter and school closure list ready by next month.
