The Georgia Professional Standards Commission can impose sanctions ranging from a warning to revocation of an educator's state certification.
The Glynn County school board fired Mr. Bull on Feb. 20 after it learned he had used the BlackBerry to send and receive sexually explicit e-mail on Feb. 18 while staying at a Savannah motel for a regional education meeting in Statesboro, more than 50 miles away.
By law, the school board was required to notify the commission of Mr. Bull's termination, which it said was for cause - improper use of school property. Bull is accused of violating state educator ethics standards by misusing school property and by unprofessional conduct in the matter, according to a complaint included in the notification.
During its regular meeting Thursday, the commission agreed to investigate, said Gary Walker, director of its Educator Ethics Division.
The commission only has authority in Georgia, but it reports any disciplinary action it takes to a nationwide education database.
Mr. Bull will have an opportunity to respond to the complaint and present evidence on his own behalf during a subsequent hearing. He can appeal any disciplinary action.
