Activity Vouchers
In fact, why can't we make a voucher out of this, whereby money is pinned to the student to spend at the high school, the latter being enjoined from charging fees or imposing required fund-raising services on either the students or the parents.
Unlike full vouchers, this money never leaves the district. Unused funds can be reallocated as scholarships for the multi-taskers out there that play three sports, take band, and are in the class play, more than one voucher would otherwise cover. But the Administration cannot use the funds to buy the textbooks they forgot to budget for. Nor are these funds on the table when bargaining with the Unions.
It's that last requirement that would be the first reason why not.
