Opening statements are set to begin Monday in the trial of a dozen former Atlanta Public Schools educators and administrators accused of participating in a test cheating conspiracy.

It took more than six weeks to select 12 jurors and 11 alternate jurors, and the trial is expected to last several months.

The 12 former administrators, principals, testing coordinators and teachers face racketeering charges. Individual charges include influencing witnesses and lying to state investigators.

Jurors won't hear arguments from lawyers for former superintendent Beverly Hall. Her trial was delayed because she's undergoing treatment for cancer.

A grand jury last year indicted 35 educators and administrators, but prosecutors have agreed to plea deals with 21 of them. Several could testify against their former colleagues.
