Roberson said all changes made in May before final grades were submitted were justified and reflect updates made after students completed makeup work using online credit recovery.
“We did not find any wrongdoing on the part of the teachers nor on the part of the principal,” Roberson said, referring to Principal Tonia Mason, who resigned this summer. “This was a legitimate procedure that is in place throughout the system.”
Roberson said that he received a complaint that grades were fraudulently changed between 25 and 75 times last year involving seniors at the school and that he began investigating Tuesday.
Roberson said his staff interviewed several employees on the issue and did not find any evidence of wrongdoing.
