The grading system for Indiana public schools will be changing a little. The State Board of Education has approved new A through F grading rules for Indiana schools. Now, half the score that figures into A thorough F grades for each school will be based on how much students improve on their prior scores and half on how many kids pass. The changes will likely result in slightly fewer A-grade schools but it will also mean fewer failing schools as well as giving leaders a better idea of how schools are performing. Some board members are concerned this was not brought up for public comment and that it could be rejected by the attorney general's office.
