I agree with Bealzebub's note of caution - in a market where supply exceeds demand you might face a problem if they are used as a selection criteria. If you have 5/10/50 candidates who are all much of a muchness on paper, and you need a way of cutting down the number of candidates to interview , qualifications is a sifting method which is difficult to challenge.
In my first experience of recruitment, I couldn't understand how my more experienced colleagues where ploughing through their piles of applications so quickly - "We're getting rid of all the applications in blue pen - the advert says complete in black, and if they can't follow that simple instruction...." (it was for an admin job and a long time ago...
