Atlanta public school officials appeared on Friday before a county grand jury investigating alleged cheating by teachers and principals on standardized tests and turned over 95 volumes of subpoenaed documents, officials said.
The documents were on DVDs, CDs and cassettes, Atlanta Public Schools spokesman Keith Bromery said in a statement.
The school system asked for a three-week extension to deliver other documents subpoenaed by the Fulton County grand jury, Bromery said.
The district needs more time to put the documents in a digital format, he said.
"The district is awaiting a response to this request, although the Fulton County District Attorney indicated that he will support the request for an extension," Bromery said.
