Depends if you're teaching at a phase 1 establishment i think. I had to go to RAF Halton and do DIT cse as part of it had a ''care of trainee's'' package. Rest of it was revision and a waste of my time.
Hmmmm MOIT/BIT/DIT at our RTW most of us have a mix of them, however we all recently had to do a DIT update course, despite being schools instructors of one sort of another.....go figure as most of the pre requesites (?) for those courses is MOIT/BIT/DIT! We are also having to do the T3 course. I suppose that until some one in the know makes the decision as to which one is best then it's a case of get away with what you have if you can.
IMOO MOIT is by far the best of the lot how many schools courses teach by BIT or DIT?
