Libertarians and Education

What is the libertarian stance on educational funding and curricula.  In particular, as it applies to post-secondary level education, universities or trade schools.

maybe the reason private schools are doing good atm. is because they have the students of people with money. these kids are most like more paced than regular kids, so they have more support/pressure from home to study harder. The parents can also afford to pay for the kids in the private schools(a larger amount than what the public schools get pr child), so the private schools can buy better things/techers/books/whatever for the kids, than the public schools can.
