The Atlanta Journal Constitution reports that former North Atlanta High School Principal Mark MyGrant received immunity from the Georgia Bureau of Investigation as the agency looked into allegations of cheating in Atlanta Public Schools.

The AJC story, available to subscribers only, says that during Tuesday’s testimony in the trial of a former APS official, MyGrant testified that he tipped off APS officials about how a top-level administrator planned to respond to the GBI investigation. MyGrant testified that he had done nothing wrong and that he felt reporting the matter to APS officials was the right thing to do.

APS officials removed MyGrant and other North Atlanta administrators from the high school in October of last year, a move that infuriated parents in Buckhead. At the time, APS said the shakeup was related to low test scores at the school.

In the aftermath of MyGrant’s removal, APS officials revealed they were looking into allegations of grade changing at the school. A report on the various allegations at North Atlanta High is expected to be released soon.

North Atlanta High wasn’t implicated in the test cheating that resulted in the removal of dozens of teachers and the indictment of former APS officials, including former Superintendent Beverly Hall.
