DD is 15 and is one of the top people in her age group nationally at a particular sport. It's pretty unlikely that she'll "go professional" or make any serious money from it, but she has the opportunity to get a full sports scholarship to a US university, where she would compete at the NCAA level. This would include rent/living costs as well as tuition fees, and would mean that she would graduate debt free (which she certainly wouldn't in the UK!) so it seems like an incredible offer.
My only concern is that the particular universities that are good for her sport, are not well-known in the UK. As it is pretty likely that she'll return to the UK afterwards, I'm wondering if having a degree from an institute no-one here has heard of would affect her job prospects.
She's not Oxbridge material, but she's reasonably bright and I'm pretty sure that she would be able to get into universities of the Exeter/Warwick calibre. If she goes to the US, she's looking at colleges such as Baylor (in Texas) and Louisville (in Kentucky).
