... do they play 2 sports at County level?
I'm asking because our school only does BTec PE, not GCSE. When I asked the reason why they said it was partly because the GCSE reforms had made it very difficult to get the higher grades, and that students would realistically need to play 2 sports at County level in order to be in with any chance of achieving an 8/9. (It's a small school so possibly they could only choose one or the other and decided to go for the one that would be more inclusive across the ability range).
