Obviously I'm just going to have to work hard At what I'm doing now to pass the framework but wondered if I wanted to change after would my apprenticeship help me in getting a job in the planning office or anything.
OK - in part, you've answered your own question.
The practical skills develop with experience - up to a certain level based on your individual capability. I used to struggle a bit with some of the turning exercises we were given as apprentices (and my apprenticeship was electrical, so they weren't trying to make toolmakers out of us) - so I used to make little "foreigners" during my lunchbreak just to get more experience of actually handling the lathe and understanding what it (and I) was capable of - I think my mum has still got a small pair of brass candlesticks I made as a bit of a self test that I could make one (easy) and then make a dimensionally exact copy (not so easy). They are threaded in two parts so I could take them out a bit at a time in my grub box
From there, then if you decide that it really isn't for you (or if you master it, you want more challenges) then look at further education - the combination of an apprenticeship followed by say a HND then a degree would more than help you make a move, most empoyers would snap you up in my experience.
There is absolutely no problem with doing a trade first and then progressing - in fact, I would say that it is the formation of some of the very best engineers
Good luck and stick at it
