They tried to do this some years ago, the difficulty is that we all qualified in different ways. One of my stylists had apprentiship papers, I had city and guilds, some had NVQ's. They would only accept the nvq's!!
My city and guilds advanced hairdressing and mastercrafts apparently do not count, and I'm damned if I'm gonna sit a dopey nvq2 just to satisfy a box ticker.My stylist with a hard won apprentiship paper and 35 years experience felt the same.
As I trade test people who are "qualified" for stylist jobs, I can confirm that you can hold an nvq2 and be incompetant and downright dangerous. The qualification simply means that you attended the college.
