But a large-scale, countrywide experiment in school vouchers has taken place — in Chile. And Chile offers an instructive and cautionary tale about how school vouchers affect education. How Chile’s school voucher system worksChile has one of the world’s purest examples of a voucherized education system, established by the dictator Augusto Pinochet in 1980.

The aggregate socioeconomic status of a school more strongly predicts test-score achievement in voucher schools than it does in public schools.
