The parents.

Bingo.

In my graduating class, there were two students who violated some rules near the end of the Senior year, and the administration said it would not let them walk at graduation. Well, the students of both parents paid the school a visit, and presto, their children walked.

Parental pressure would force private schools not to accpet voucher students if any off these scenarios came to pass.
