hya m8,
i got my level 2,  3 years back how it works an assessor comes out  once a week or so over I think it was around 12 weeks, we had homework, which he helped out with,he took pictures of us skimming dabbing and tacking, then once we had done the 12 weeks we had a seperate touch screen test on health and safety that we had to study in home work, although it is mostly common sence,
now i have been a plasterer all my life 30 odd years the assessor a very nice bloke was a painter, where is the sence in that?
the NVQ2 is needed to work on most sites now, as it has to be recorded in the induction, and i think it is going to be made compulsry in the next few years
my thoughts on this NVQ is a complete farse I was working 2 and 1 and our labourer asked if Iwould bluff him through so of course I did, he can trowel up but thats it,
the 3 of us are now on par as plasterers as he was pictured putting boards on to dabbing and holding a st edge over the wall  /nailed a plasterboard/ and trowled a wall up, and did his homework and took the  health safety test
you can go to collage and gain this NVQ2 but it will cost you
