The mayor of Stockholm gave some brief remarks at the closing dinner of the Mont Pelerin Society meeting and mentioned that the number of students in private schools had skyrocketed after the implementation of Sweden’s school choice program. Intrigued, I emailed the folks at one of the nation’s research organizations to ask for some details.

The figures are impressive. The number of students attending private high schools has jumped from 1.7 percent in 1992 to 19.5 percent in 2008. Not surprisingly, the quality of education is high. Indeed, researchers have looked at the data and concluded, “Our findings support the hypothesis that school results in public schools improve due to competition.”
