How long is Air Force Tech school, in general?
 

My boyfriend goes right after BMT, he says it should be around 3-5 months of tech school.
How does that work? Can he finish early if he gets all his work done fast and stuff?

He'll be done when the Air Force says he's done. His schooling time will vary depending on what he's going for and the job he'll be doing. Just to goive you an example, my Son's was 3 months (Computer Networking Security) and my Daughter-in-Law's was 5 months (Nursing). I was in the Army and my schooling was 8 months long.
