The 50,000-student school system was the first in the nation to lose accreditation since 1969. The Southern Association of Colleges and Schools (SACS) revoked the school district's accreditation on August 28, 2008. This makes only the second system in the nation to do so since 1960. A grand jury investigated and considered possible criminal indictments against the Clayton County School Board. At issue was whether the school board committed malfeasance in ignoring the shortcomings of the school system and violating its own rules concerning the awarding of bids of contracts.
