Almost ALL of the NA's I know either went to college or are just high school grads. Most of them are quite old however, so when they went to high school there wasn't as much pressure to get a university degree as there is today (and for the past 10 years or so). Also a number of them are people who worked for 10 years or so in a completely different industry (i.e. factory work) and then they got sick of it, and the only "good" job they could get training for without killing themselves, was NetworkAdmin.
BTW: In Canada, "college" = vocational school in US (roughly).
