2 types of NVQ? No!
VCTC, C&G, SVQ (Scotland only) and NVQ.
Unit 19 is a UNIT of the full Beauty therapy NVQ and is at level3.
Unit 19 is not an NVQ but only one unit of the whole NVQ as above.
Soon (September?) Nails will have its own WHOLE NVQ qualification ... it will no longer be just one unit of someone elses NVQ. It will be full of units of its own and completion of all will lead to a full NVQ qualification (which nails never has been before) in Nails.
Years ago the nail unit was B13 then changed to C19 (which was good because it belonged in the higher skill area C)
I have done them both (for the experience) as well as D32, D33, D34 and D36. (Assessors Qualifications.) Those were the days when Marion Newman and Jacqui Jefford badgered me to do them. cause they said it was good for me!!
