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.
School Board Chairwoman Ericka Davis announced her resignation on April 2, 2008, amidst the allegations. Clayton County Commission Chairman Eldrin Bell has called for the resignations of all Clayton County School Board Members.  Amid controversy and orders for the police to quiet citizens, the Clayton County School Board hired a new temporary superintendent on April 26, 2008. This was despite the fact that the new superintendent did not meet the qualifications set forth by SACS. 
The Clayton County Public School System was re-accredited by SACS on May 1, 2009.

It voted for Governor Carter in 1976 with around 65 percent of the vote, but then voting for President Reagan, even with over seventy percent of the vote in 1984. However, due to extensive black in-migration, starting in 1992 Clayton County has swung heavily Democratic, and is now one of the most Democratic counties in the country. It has given the Democratic presidential candidate over eighty percent of the vote in every election since 2008. In 2016, for instance, it gave Hillary Clinton 84 percent of the vote, her strongest showing in the state.
