Georgia school officials are working to develop guidelines for screening prospective and current bus drivers, the Atlanta Journal-Constitution reported March 1.

The effort comes in response to an investigation by the Journal-Constitution and WSB/Channel 2, which found 342 Georgia bus drivers with criminal records, hundreds with histories of suspended licenses, and dozens with drunken driving convictions.

“The guidelines have not been clear enough, so nobody is operating on the same page,” Gene Thomason, president of the Georgia Association for Pupil Transportation, told the Journal-Constitution.

The state currently does not recommend how school districts should evaluate driving histories, and many districts have no written policies.

A committee of four school system transportation directors and two state-level school transportation officials is expected to issue its recommendations in June, Thomason said.
