Columbus City Schools' internal auditor shared the results of her investigation with the school board's accountability committee on Thursday.
According to internal auditor Carolyn Smith, her investigation revealed three incidents of grade-changing.
Smith said that in two cases, vice principals changed grades. In the other case, a regional director changed a grade.
Smith said that she also found that some students were dropped off attendance roles as 10th graders but were later re-enrolled as ninth-graders.
The internal auditor recommended that the district implement a fraud-reporting hotline and a district-wide whistle-blower policy.
Columbus City Schools Superintendent Gene Harris told the committee that she hoped the whistle-blower policy could be presented to the board of education at its next meeting in January.
