Ok a history of approved card as I seen it in 1975 when i started my time you had to have your B or approved C&G qualification plus spend 2 years with the same firm to get your approved ticket before that you your employer could apply for it but again 2 years plus you had to show you could run a job now if you got your A or electricians C&G qualification but at the time go no further if you started your time in 1973 and did not pass any qualifications then you had to serve a 5th year as an improver to get your sparks tickets.
Now if you passed all of your exams your employer had the right to with hold your approved ticket for 1 year if he thought you were not up to it in other words you had to do 3 years after your electricians ticket to gain approved so to me the NVQ 3 is the B or approved C&G.
Now remember I live in Scotland where at the time unless you were a government worker ie PSA/DOE electricians labourer was a no no because if you could afford a labourer you could take on an apprentice only in the early 80s they changed the 2 years with an employer rule to 2 years with several employers plus the poor Yopper or Youth Oppertunity guys had to serve 5 years
As far as I know, the old system was A- spark B- approved spark, C -Technician.
To be honest, the system hasn't changed that much, it;s just the codings that confuse people.
So here goes.
Old system = 2360 part 1 now becomes 2330 level 2
2360 part 2 now becomes 2330 level 3
Under old system, 2360 part 1 had practical element, AM 1, now obsolete but can be taken as NVQ level 2 (I did this).
Under old and new system, 2360/2330 has practical element AM 2, revised, but still current and still a rigorous test!
so the underpinning knowledge element has changed coding, and perhaps style in the advent of an element of the multiple choice part. I stress here that there are extended question papers too.
That takes care of the A grade part, i.e. the minimum requirement for a 'sparks' card.
The old part 'B' is now the 2391 (actually been replaced in coding only) and with two years endorsement from a company will entitle the holder to apply for 'approved' status.
The part 'C' as far as I know is the design part, and this is where I will leave others to fill in here, or correct what I have asserted.
Please bear in mind, this is all (very hard to find) information, that I have pieced together from years in the trade and training. I hope it helps, and if I am wrong, then let's hope someone puts me straight because the college wouldn't give a straight answer!
Cheers.
