I can't speak for the present, but a few years back there were some real issues with the program at NAIT, where students were not even being taught some of the key basics of announcing, like how to breathe when saying more than one breath's worth of words.
The best way to get current information is from the employers who are seeing the latest grads that actually were able to follow their chosen career path: find someone at a radio station who has actually hired a NAIT grad or two recently, and see if you can find out from them the good and bad of NAIT Radio training.
For example, The Goat in Lloydminster used to have NAIT interns and may even have hired some of them fresh out of school after their internship.

On a related issue, Marty Forbes recently told me about a talk he gave to a national conference of broadcast educators, on most broadcast school's failure to teach the use of Social Media as a part of both a radio station's and a broadcaster's essential toolkit.
Finally, from personal experience, I would say that going into a post-secondary program with your eyes open, as to what the program is lacking, can work quite well if you make up for those deficiencies in your spare time by doing self-study, etc. Of course, it is important to mention those areas of self-study in your resume, so that savvy employers will not pass you by during the hiring process.
