AUGUSTA — The Maine Charter Commission voted 5-1 today to approve the plan for a charter school in Cornville for 2012.

Proponents say they expect the school will open prior to Oct. 1. The commission two weeks ago had voted not to approve the plan, but the proponents convinced the board to reconsider after it submitted a revised budget that showed a $25,000 surplus after the close of the first school year.

The school will have at least 45 students.
