(AJC) — Numerous Atlanta Public Schools employees have confessed to changing students’ test papers, providing answers to students or watching others manipulate tests, according to an official briefed on the state’s investigation into cheating on standardized tests. The official, who was not authorized to discuss the investigation and spoke on the condition of anonymity, said some teachers are telling investigators, “I’m guilty. Here’s what I did. Here’s what I know happened.” The revelation comes as criminal charges against APS employees appear increasingly likely as a result of the state’s investigation. GBI director Vernon Keenan and two special investigators on Monday met with Fulton County District Attorney Paul Howard.
