The interim superintendent of Columbus (Ohio) schools says he is working to fire employees implicated in a district data scandal. The Columbus Dispatch says Superintendent Dan Good has been advising those with ties to the scandal to leave the district. For the past seven months, Columbus school officials have had the names of as many as 30 employees who the internal auditor found manipulated student data. There has been no action against employees. Four administrators connected to the scandal have resigned. The latest is Amy Dennis, who was director of pupil personnel. District records show that Dennis, when she was principal of Whetstone High School, deleted nearly 8,000 student absences between 2006 and 2010 and changed or deleted at least 30 final student grades.
