How Do School Vouchers Work

How do school vouchers work?

A) They allow schools to allocate resources according to their own assessments of where funding is needed.
B) They allow parents to behave more like consumers. They can transfer from a low-performing to a more successful school, and the funding should follow the student.
C) They allow schools to trade and transfer students to even out challenging student groups vs. high-performing student groups.
D) They provide full school choice for parents to use for whatever reason and to enroll their children in whatever school they prefer for public education.
