The state Board of Education voted Thursday to approve the system, clearing the way to release the letter grades on Oct. 20.
Last month, the board had discussed a plan that would assign As to the top 10 percent of schools and districts, which led to an outcry from critics who said the board was artificially limiting the number of schools who could earn that grade.
The department received 139 public comments about the plan, all negative. State officials, though, say that was a misunderstanding and that they instead will award As to as many schools and districts as reach particular scoring levels in the state’s rating system.
