A hundred years ago, eight and a half per cent of American seventeen-year-olds had a high-school degree, and two per cent of twenty-three-year-olds had a college degree. Now, on any given weekday morning, you will find something like fifty million Americans, about a sixth of the population, sitting under the roof of a public-school building, and twenty million more are students or on the faculty or the staff of an institution of higher learning. Education is nowhere mentioned in the Constitution; the creation of the world’s first system of universal public education–from kindergarten through high school–and of mass higher education is one of the great achievements of American democracy. It embodies a faith in the capabilities of ordinary people that the Founders simply didn’t have.
It is also, like democracy itself, loose, shaggy, and inefficient, full of redundancies and conflicting goals. It serves many constituencies and interest groups, each of which, in the manner of the parable of the blind men and the elephant, sees its purpose differently. But, by the fundamental test of attractiveness to students and their families, the system–which is one of the world’s most ethnically diverse and decentralized–is, as a whole, succeeding. Enrollment in charter schools is growing rapidly, but so is enrollment in old-fashioned public schools, and enrollments are rising at all levels. Those who complete a higher education still do better economically. Measures of how much American students are learning–compared to the past, and compared to students in other countries–are holding steady, for the most part, even as more people are going to school.
