Principal of troubled charter school resigns

The principal of a Cobb County school whose charter will expire by summer has resigned.

Imagine International Academy of Mableton's charter renewal request was denied by the Cobb school board last week. On Monday, Principal Marcus Barber quit, said Henry Stephens, a regional director with school manager the Imagine Company.

Barber suffered from a health condition and learned last week that it had worsened. "I guess it was his doctor's recommendation," Stephens said. He said the school was still trying to renew its charter.
