Initial Skills Training (Tech School): AF Technical School graduation results in the award of a 3-skill level (apprentice). Following Air Force Basic Training, airmen in this AFSC attend the following course(s):
- Course # E3ABR3D133 01AA, Apprentice RF Transmissions Systems Specialist course at Keesler AFB, MS - approximately 110 class days.
Certification Training: After tech school, individuals report to their permanent duty assignment, where they are entered into 5-level (technician) upgrade training. This training is a combination of on-the-job task certification, and enrollment in a correspondence course called a Career Development Course (CDC). Once the airman's trainer(s) have certified that they are qualified to perform all tasks related to that assignment, and once they complete the CDC, including the final closed-book written test, they are upgraded to the 5-skill level, and are considered to be "certified" to perform their job with minimal supervision.
Advanced Training: Upon achieving the rank of Staff Sergeant, airmen are entered into 7-level (craftsman) training. A craftsman can expect to fill various supervisory and management positions such as shift leader, element NCOIC (Noncommissioned Officer in Charge), flight superintendent, and various staff positions. Upon promotion to the rank of Senior Master Sergeant, personnel convert to AFSC 3D190, Cyber Operations Superintendent. 3D190 personnel provide direct supervision and management to personnel in AFSCs 3D1X1, 3D1X2, 3D1X3, 3D1X4, 3D1X5, 3D1X6, and 3D0X7. A 9-level can expect to fill positions such as flight chief, superintendent, and various staff NCOIC jobs.
Assignment Locations: Virtually any Air Force Base.
