Gov. Sonny Perdue has named a former district attorney and a former Georgia attorney general as special investigators to look into allegations of test cheating in two school districts.

Perdue said Friday that former DeKalb County district attorney Bob Wilson and former attorney general Mike Bowers will launch a probe into accusations that educators changed students' tests in Atlanta Public Schools and Dougherty County schools in spring 2009.

Wilson served three terms as lead attorney in DeKalb County starting in 1980. Bowers was attorney general from 1981 to 1997.

Perdue announced the special probe Wednesday after he said the two districts performed "woefully inadequate" investigations on their own.

A statewide audit released in the spring showed an unusually high number of erasures on first- through eighth-grade standardized tests taken in 2009.
