More Indiana schools have received top state ratings under results from last spring’s ISTEP standardized exams. Ratings released Wednesday by the Indiana Department of Education show 29.5 percent of the state’s schools received an A grade for 2016-17, up about 6 percentage points from the previous school year. In all, five of the dozen schools at Muncie are rated by the state as D schools. MCS Superintendent Steve Baule says he does not put much value in the report. He says the grades are tied to poverty rates. Among local schools graded as F schools include those in Anderson, Marion, and Kokomo.
