If you’ve been excluded from a school and you’re looking for a new school to go to, other schools can refuse to accept you while you’re currently excluded. However, this doesn’t mean that just because you were once excluded from a school, any other school can continue to refuse you.
If you’re excluded from school A, but you’re taken in by school B, then school C can’t refuse to accept you if you’re eligible to go there (for example if you’re in school C’s home zone). The only exception is the school that excluded you – they can continue to refuse to accept you indefinitely.
