I started my cadetship with the dreaded Nats in 1996.
There were 23 on my course. This is how I think it worked out:
7 posted to TC of which 4 now valid, 2 of the 7 now valid at MACC the other left to be a pilot.
4 went to airfields and validated.
The rest were chopped or were recoursed (2). 3 have ATCO jobs outside Nats at airfields.
So not bad really because I think the predicted failure rate is more like two thirds!!
If you were joining Nats you could come to TC and train on Z watch as we have a 100% pass rate with new students in the last 3 years!! - And our reward for such an achievement? Other watches with worse training records are trying to poach our controllers to even numbers up!! ( Sorry, just a bit of TC moaning )
Anyway sod failure rates, if you are good enough you'll make it!!
Good luck
