According to unofficial accountability results, more Mississippi school districts were rated as A than F. The Commission on School Accreditation reviewed the unofficial school ratings from the most recent school year on Tuesday. All in all, 31 districts received an A rating, 35 were rated B, 35 were rated C, 35 were rated M, and 35 were rated M. 23 districts were given the D rating, while 19 were given the F rating. Nearly a third of these districts had their school ratings improved by a letter grade. These ratings will not become official until they are approved by the Mississippi Board of Education at their Thursday meeting. Carey Wright, the state superintendent of education, said Tuesday that Mississippi schools and districts are performing at higher levels every year and that their grades show how well they are serving children in their classrooms. These ratings are released each year by the department of education to assess how school districts are performing in terms of student progress and achievement. The A-F ratings are based on many factors. Ratings are assigned at the high school and district levels based on growth and proficiency in a variety of subjects, including reading, math and U.S. History, as well as graduation rates, ACT scores, and participation in accelerated courses like AP courses and dual enrollment. The elementary and middle schools are graded in the same way, except for higher-level testing and graduation rates. Schools with 12th grades were used to be graded on the 1,000-point scale. Schools without such a grade were graded using a 700-point scale. This meant that elementary and middle schools used one scale, while high schools used the other. Non-traditional high schools, which include grades beyond the traditional 9-12 model, received an adjusted score for the first time. According to the department, all schools that were adjusted received a higher total point score, while 43 of the 80 schools received a higher letter grade.
