A grand jury indicted about three dozen educators Friday in one of the nation's largest cheating scandals that rocked Atlanta's public schools.

The indictment named the former Superintendent Beverly Hall as well as several high-level administrators, principals and teachers. Hall faces charges including racketeering, false statements and theft. She retired just days before the 2011 probe was released, and has previously denied the allegations.

A state investigation in 2011 found cheating by nearly 180 educators in 44 Atlanta schools. Educators gave answers to students or changed answers on tests after they were turned in, investigators said. Teachers who tried to report it faced retaliation, creating a culture of "fear and intimidation" in the district.

The cheating came to light after The Atlanta Journal-Constitution reported that some scores were statistically improbable.
