LittleChubbster, you sound like an excellent teacher. If dd's teacher thought along those lines I would be far happier. I had hoped maybe it would be a different teacher for GCSE, but apparently the current teacher is HOD, so it is unlikely.
FWIW, I don't see it as an easy option - though dd does, and I will be explaining some of what I have learned on this thread with her. I'm not being snobby. DD isn't brilliantly academically minded in any case, and she does have to take a tech so my reservations are not at all about a preference for academic subjects.
She has no desire to work in food at all (which is a pity I think, but her choice!). She has said she simply would like a qualification that would recognise her cooking skills! 
She has a choice between DT or Food. DT seems to be a design and technology GCSE. I guess it is like the Design and Communication GCSE of the 90s. Technical drawing, creating models, etc. Graphic design I guess would be the closest? Clearly most schools have a slightly different system nowadays, so I can see the confusion.
Catering sounds really good, shame that isn't an option! good luck to your ds EllenJanesthickerknickers!
Food hygiene is very hit and miss. A lesson was cancelled, they left ingredients in the freezer for next week. Problem was, meat had already been frozen once, so had to be binned. She made a curry and the teacher insisted the chicken reached 70c before anything else was added to the pan, so that was safe, but by the time the spices, etc were added and cooked, it was like shoe leather. The burgers didn't cook, but the teacher told them that oven baking is the 'normal' way to cook burgers.
It really is chronic. They couldn't make bread dough so when they were looking at different ways of shaping bread they asked for flour and marg to send in three weeks running. Might as well have used play dough.
I wanted to do Art. My parents didn't want me to do a non academic subject though. I don't regret it though.
I really appreciated all the comments though, and I am takign them on board and will be having a long chat with the teacher. I think I shall ask about some of the skills on this thread being taught :)
