The Clayton County School District led the state in academic progress over the past three years, based on lists of ‘reward schools’ released by the state Department of Education Tuesday.

Reward schools are those with a high percentage of poor students that make strong academic progress or have high levels of academic performance over a three-year time period.

Clayton had 17 reward schools. No other district in the state had as many.

The department categorizes schools as being a reward, focus, alert or priority school based on progress or academic performance. Reward schools are held up for public praise; the state directs assistance to low-performing schools with other designations.

The department released separate lists of reward schools being honored for high levels of progress and for high performance.

Four schools each in Atlanta Public Schools, Fulton, Gwinnett and Rockdale were named reward schools based on high academic performance.

“The schools on this list represent some of the finest efforts being put forth in Georgia education,” State School Superintendent Dr. John Barge said. “The educators, parents, students, and communities who came together to move these schools forward should take great pride in the results.”

Last month, the department released its list of alert schools, pointing out those with low academic performance and low levels of progress.
