Military service performed after the last year of Oklahoma membership service shall not qualify as military service. A member who returns to Oklahoma public education employment after serving in the military shall purchase that military service in the same manner as a new member of TRS: i.e., the member must have two (2) years of Oklahoma service after the military service for each year of military service purchased. No military service can be used to meet the minimum requirement of five (5) full years of employment in the public schools of Oklahoma to qualify for vesting and retirement benefits.
