School Choice Research

The vast majority of sound empirical studies comparing competitive education markets to state-run school monopolies give the edge to markets. A few find no significant differences, and only the tiniest percentage find any sort of advantage to government operated schools. Moreover, the superiority of free market education is not limited to higher student achievement, but extends to a variety of positive social effects as well.
