I would want to know that she wouldnt be ripped off as an adult. So if you think her reading, writing and maths skills are good enough to make sure she isnt scammed, can budget etc I would be happy enough. If she wants to go into beauty she may be working with chemicals such as hair dyes, I would want to know she understand percentages and measurements. She doesnt need the gcse to prove she does.
Education wise you need to keep evidence of her learning. I would look at classes and experiences that had paperwork you can keep as proof. A credible first aid course with certificate for example.
In fact first aid would be something I would insist she learned no arguements.
Then I would look at what she is interested in. If she likes art look at local art classes. Make up masterclasses are big at the moment if she is interested in beauty. Cookery and baking, basic mechanics even. Anything that promotes life skills.
Her world won't implode if she doesnt get gcses. It is a bit of paper. And I say this as an adult with a degree. But I would want her to go off into the world with the skills to live as an adult by herself if everything goes pear shaped.
Plenty of students go off to uni full of facts, but they cant work out a bus timetable, cook themselves a filling dinner or buy a weeks worth of shopping for £20.
A bit random, but I would also make sure that she could swim and would encourage her to do a life saving course.
