Down with ageism.
How about:
"What skills and maturity markers should indicate how much input a kid should have in their schooling?"
So, if I have a brilliant but short-sighted and impulsive kid, then I solicit situational feedback and make the adult decision. If they are long-sighted and thoughtful and able to weigh pros and cons and consider the value of the situation for their future self, then they should be a key party to the decision. If the decision is fuzzy with conflicting rational points, then I'd take the burden as the one whose unconscious experience is providing secondary feelings to it.
