After Hereford, we Techies went to Scampton for Trade Management Training which was orientated around line teams, overseeing aircraft engine starts and marshalling using Hunters [including Avpin starts with the asbestos glove] then learning all the F700 documentation and responsibility for supervision and over-signatures. I felt that it gave me a thorough grounding in my management competency and accredited me with a significant amount of responsibility much quicker than would have been expected in a civilian equivalent employment.
I used to do most of that as a JT, indeed the only person out on an engine run would be me in the cockpit and a bod on the extension lead outside.
Civilian qualifications as an LAE includes runs, and taxiing etc, I also do items that would probably be a Wing Commander and above.
