What are the requirements to be an AIT instructor?

start with schools required, ABIC, SGITC, OC/T, for most, then there is the MOS qualifier

SGT Alex Monreal - I was an AIT Instructor and have an answer for My MOS, don't know if you are looking for specifics on 13D or what...
First, you need to have gone through AIT for your MOS, 24K for me. That's Advanced Hawk (CW) Missile Systems. The CW is for Continuous Wave. Mine was 43 weeks.
Then, you need to have been deployed within your MOS and I was, then came back to Redstone Arsenal, AL and go through the 2 week MOI school. That's the ARMY acronym for "Method Of Instruction". Then you can go to the school and teach only what you specialized in. I was a Tracker I & II Specialist for the Hawk HIPIR radar. I was in a metal container where one side wall WAS the entire test console. I could hook up a Tracker i or II module to the desk portion of that wall and it simulated the HIPIR radar. The set of manuals was huge, 3 foot wide when opened and there were several manuals for each module. We had to use plastic screwdrivers and wear static straps on our wrist. Some of the adjustments were so wild that you had to turn one of maybe 50 screws (potentiometers) 42 times, counter-clockwise to get to the null point on the meter for that adjustment then start back clockwise until the meter moved to the setting called out in the manual. (These "vans" like I was in could be lifted by cranes and put on the back of a deuce and a 1/2 to go to field sites )
If you did all of that correctly and the needle never moved then you knew you had a blown resistor or capacitor or even a microchip. Out comes the soldering iron, the solder-sucker and you had to know how to read the colored bands on the resistor to get one out of the drawer for an exact match. Capacitor values were labeled and the chips had part numbers. Solder in the replacement and start that adjustment again. I know, I know, it sounds complex and boring but I enjoyed it.
So, long story short = Go thru school, be deployed, go thru Instructor School, go teach. You have classroom training and hands on equipment training.
Good luck!

SGT (Join to see) I would contact your branch manager. I will look and see what I can find. Good Luck! MILPER messages on the HRC site is a good starting point.

Call branch. If they can't point you in the right direction, try to get in to see the USAFAS CSM or the 428th FA BDE CSM for a shoe in the door.

If you can get selected by branch and Once you get to wherever you are going you have to have CTC AND ABIC.
Your ABIC has be less then 24 months old.
You will get the CTC and ABIC when you get there.

I just left 1/78 FA (the FA AIT BN) as an AIT PSG last May. First of all, you need to be a SSG. You do not need to deploy to be an instructor. The schools mentioned by others you can't go to until you are assigned as an instructor. You can try calling branch and get a pin point assignment. However, you should be warned that branch does not slot instructors. What is does is slot you for 428th FA BDE, and the BDE CSM decides where you go. You can certainly contact the CSM, or the 1/78 FA BN CSM and try to request being slotted, just understand that the BDE has other requirements as well.
