I teach the C&G short Electrical courses 2382, 2377, 2394 and 2395, and previously the 2391.
The reason that they have changed has nothing to do with anyone wanting to make things easier, they have not been dumbed down, and you will still need to be at the top of your game to pass them. C&G and all the other awarding bodies had to align their qualifications to the QCF system. This involved breaking courses down into units, so that anyone doing a different course, as an example C&G 2357, could use any credits gained in qualification as credit towards another, so that they don't have to do the same thing twice. If you get a certificate like the 2394, it will have all the unit credits printed on it, so if you do another course like an EAL NVQ level 3, then any credits you have from 2394 can be used to exempt you from any part of the NVQ where appropriate. We call it Acquired Prior Learning (APL). If you came to me wanting to do a L3 NVQ i would ask to see your current qualifications, and would APL these to the NVQ, and then you would only have to do the bits you weren't exempt from.
