Atlanta Public Schools has lost another high-ranking official: Randolph Bynum, the city district's associate superintendent for high schools, was named this week as the new superintendent of schools in Sumter County, S.C.

Bynum officially starts July 1. APS's deputy superintendent for instruction, Kathy Augustine, was picked last week as a lone finalist to lead the suburban DeSoto Independent School District in Texas. Both of their departures coincide with that of Atlanta Superintendent Beverly Hall, who will leave the district June 30 after a 12-year tenure.
