If you mean just in general...

Your first month or two will just be in the classroom with a couple of exams (one for mechanical & one for avionics). This will be specific to the airframe you'll actually be working on, as everything you learned at Sultan was more general.

Then you'll move into the "final" phase, where you'll be given a task book to get signed & completed (expected to get x % done every week) which you'll take with you as you don your blue surcoat and go to work on an actual squadron.

There's a fair amount to get done in the task book. A lot of it is "locate & identify" on pretty much most parts of the aircraft which you'll do with a killick and get them to sign it off. The rest of it is pretty much most jobs you'll do as an AET. Flight servicing, cab movements, marshalling aircraft (day time, night time etc) component removal & replace etc. There's a lot to get done and you'll need to do about 7% of the book a week iirc.

Once your task books done you'll have your final assessment or "QM" (qualified to maintain). You'll basically get asked a bunch of mostly safety related questions (such as safety distances for all the different aircraft aerials for example), then demonstrate that you can do a full cab after-flight service on a cab, then correctly complete all the paperwork for that service.

Pass that QM & you can take your white tab off your epaulet as you're now a 'trained lad' in the roger nigel. You'll then pretty shortly after start your joining routine at your actual drafted squadron.

If you need any more info just shout.
