Since the early 2000s, many states have introduced significant voucher programs to provide public financing for private school education. These voucher programs are deeply damaging to efforts to offer an excellent public education for all U.S. children—and this is in fact often the intention of those pushing these programs.
In Indiana, students that used the Indiana Choice Scholarship voucher program experienced an average achievement loss of 0.15 SDs in mathematics. The promise of vouchers improving educational outcomes rests on assumptions that the private sector is always and everywhere more efficient than public providers of goods and services. But the private schools that expand or are created in response to the introduction of voucher programs are often of very poor quality.
