The state auditor's office has set up a temporary hotline to allow Columbus City Schools employees to anonymously report attendance fixing cases without fear of reprisal. Auditor David Yost is investigating attendance manipulation by district officials designed to improve student scores on state tests. Yost says he's concerned that employees are afraid to talk. School officials discourage employees from talking to the media or others outside of the district about internal operations. The hotline number is (855) 554-1555.
