Go with Bob, he is the best, yes it is lots of paperwork, and headaches,

but worth it. I did my D32 & D33 (now A1 & A2) assessors awards and D34 Internal verifier awards with him. I also did my 7306 adult education and Level 4 NVQ (degree level) in training and development with him.
He is a diamond, held my hand all the way and i would not have survived without him.

Anyone who wants to do these qualifications privatly (not cheap!) should give him a call on 01722 415425.
The awards are quite hard, you have to have 5 years industry experience to be an assessor and hold the award you want to want assess. Ring Bob, he will tell you all the info.
