For the regional airports, my understanding is that you'll do ADC, go and validate it, then go back to the college for APR at some point in the future.
There are rumblings that word has come down from higher places that they're going back on this idea.
They want you to go to your approach unit having done both ADC and APR courses. You then have to validate one and start your training for the other all within six months.
I know they want people to be validated and fully operational asap but this seems a bit too quick and won't allow you much time to consolidate your first validation. Didn't it used to be much longer - as much as five years?
