A second principle is that oversight remains necessary even when vouchers and charters are up and running. Although the absence of bureaucracy is one of the biggest advantages of such schools, light-touch regulation is not the same as no regulation. As Milton Friedman, patron saint of the school-choice movement, put it, schools must meet “certain minimum standards laid down by the appropriate governmental unit”.
As Friedman also knew, markets work well only if buyers have the data with which to make an informed choice. That leads to the third principle: schools receiving public money should publish facts and figures about their performance. The best gauges are based on pupil improvement and other measures of value-added, rather than raw test scores.
