District Attorney Hayward Altman announced the decision earlier this week.
Cpl. Patrick Paquette, a part-time officer for the police department and a full-time school board officer at Tubman Middle School in Augusta, shot Jerry Conner on April 3 in Wadley when Mr. Conner approached him with a knife, according to police accounts.
Wadley Police Chief Wesley Lewis said Mr. Conner did not comply when officers ordered him to drop the weapon.
The GBI investigated the shooting and provided a report to the district attorney last month.
Mr. Paquette has been on administrative leave from the Wrens Police Department since the shooting, but Chief Lewis said he would be put back on active duty.
