The Tennessee Department of Education says problems with the standardized student assessment program weren’t caused by a cyberattack as earlier suspected and no student data was breached. The agency said the event that occurred April 17 was largely due to a change in text-to-speech configuration. The department said in a news release the vendor Questar implemented an unauthorized change in text-to-speech, which had operated successfully previously. The release said the change led to other problems experienced during TNReady online testing.
