Most apprentices will be going to college 1 day plus evening per week. Or, and i don't know if this still exists ''block release'' where the apprentice will do block term's at college....
Then you will need to add into the equation the experiences being gained under the patronage and watchful eye of a qualified electrician.
So in my book there is really no comparison, considering that on completion of that 3/4/5 year apprenticeship you will,( or should be) leaving with a core Lv 3 electrical qualification AM2 and hopefully NVQ Lv 3!! Not just an add on 17th edition, PAT qualification, and a worthless Part Pee qualification.
What's more, how anyone in their right mind, can accredit the 17th and PAT qualifications as being even remotely close to being Level 3 standard, is totally beyond my understanding!! But this lunacy results in these wannabe's having two level 3 qualifications under their belt, 5 weeks after they gave up the Tesco Shelf packing job!!
