Most schools in Jackson County lost ground this year as state accountability grades generally dropped.

Some schools held their markings from last year, and one school, Medora Junior-Senior High School, showed improvement, going from a grade of D to a B.

The Indiana Department of Education released 2015-16 A-F accountability grades earlier this week. District grades are expected to be made public at a later date.

Elementary and middle school grades are determined using a combination of percent of students passing math and English on the ISTEP test and the number of students showing growth from the previous year.

High school grades are determined using a combination of graduation rate, pass rates on End of Course Assessments in algebra and English 10 and college and career readiness achievement rates.

Brownstown Elementary School fell from an A to a C, while the middle school and high school dropped from an A to a B.

Rob Hooker, superintendent of Seymour Community School Corp., said the scores along with ISTEP results will be discussed by the school board during a public meeting at 7 p.m. Tuesday at Margaret R. Brown Elementary School.

The information will be presented by Cortland Elementary School Principal Lori Lister, who is the corporation’s test coordinator. Cortland was the only public school in the county to receive an A this year. This marked the fourth year in a row Cortland has earned the state’s highest accountability grade.

Seymour High School fell from an A to a B; Margaret R. Brown Elementary School dropped from an A to a C; Seymour Middle School fell from an A to a D; Emerson Elementary School dropped from an A to a B; Seymour-Jackson Elementary School fell from a B to a C; and Seymour-Redding Elementary School fell from an A to a B.

Parochial schools, including Trinity Lutheran High School, Lutheran Central School, St. Ambrose Catholic School and Immanuel Lutheran School, all received A’s this year. St. John’s Lutheran School at Sauers received a failing grade for its first year of state accountability, and Seymour Christian Academy received a D.

At Medora Community School Corp., the state’s second-smallest public school district, the elementary dropped from a B to a D, and the junior-senior high school improved from a D to a B.

Both Crothersville Elementary School and Crothersville Junior-Senior High School have maintained a B grade since 2014.
