State Auditor David Yost tells the Ohio Board of Education he is expanding his investigation of student attendance data fixing in the Columbus, Toledo, and Lockland districts into a statewide probe. Yost says the problem may not be local but systemic. Yost wants department employees to preserve all records and to not interfere with witnesses in the case. State Schools Superintendent Stan Heffner has said the probe could lead to fraud charges against any educators involved.
