The Pacific Collegiate School in Santa Cruz, Calif., is a public charter school. It must hold a random lottery when it has more applicants than vacancies. It is not supposed to be selective.
Yet somehow its average SAT score has risen to the top 10th of 1 percent nationally. Less than 10 percent of its students are from low-income families, compared with 40 percent in its city. Maybe that has something to do with the fact that the school is allowed to ask (not require, it emphasizes) that every family donate $3,000 and 40 hours of volunteer time a year.
As a supporter of the charter school movement, I get grief from people who say that charters — independent public schools using tax dollars — are private schools in disguise. They are almost always wrong about that, but there are enough Pacific Collegiate situations to make me wonder whether the rules need revision.
