First on the chopping block: sparsely-attended, academically faltering, skimpy-curriculum high schools that cheat students of a robust education.

The vast majority of students spurn their local schools, even though that means traveling farther. In other words, parents cast an overwhelming vote of no-confidence in some local high schools.
