Hi, I teach nvq 2 beauty therapy at the moment but are about to start teaching C&G nail services 2 in September.
I if iam being really dumb but I didnt really understand your question re NVQ's!
If you have no nvq's at the moment you would need to do level 2 first in one system and then go onto do nail technology nvq3, in which you need to learn all three systems and about 4 other units which make up the full level 3.
HTH.
:hug:
PS if you go onto the City & guilds website you should be albe to find a college which offer these courses in your area.
