The OP is over 18 though. So if they had already signed the contract then this thread would have put them in breach of contract. What penalties would the school impose for breach of contract? It's suspicious that they don't mention that.
I suspect that it's just meaningless twaddle, but contracts are, well, contracts. They're binding if agreed to by a legally competent adult.
Presumably grounds for expulsion?
I'm sure the point of this thing is purely so if there's an incredibly problematic family they can point to it and go look you agreed to this
