- Unable to demonstrate prequisite knowledge, or
- Unable to go to a school further away?
I can get the latter one, which is why I think we shouldn't just have magnet schools, we should have free, government-run magnet boarding schools. Or, alternatively, how much would it really cost to provide a chauffeur service to kids who have demonstrated intelligence and need? If schools can provide personal aides to 1% of their population, I'm sure they have the budget to treat another 1% equitably.
