A Wall Street Journal analysis of freshman data from eight highly selective colleges shows that New York City private schools and New England preparatory schools continue to send a large share of their graduates to such institutions, but some overseas schools and magnet schools focused on mathematics and science are also among the top colleges’ top feeders.

The Daewon Foreign Language High School, in Seoul, South Korea, ranks 13th on the newspaper’s list of high schools sending the largest share of their graduates to one of the eight colleges examined: Chicago, Harvard, Johns Hopkins, MIT, Pomona, Princeton, Swarthmore, and Williams.

The newspaper’s analysis — limited to high schools with at least 50 students in their graduating classes — also identified schools in Hong Kong, Taiwan, and Wales that ranked among the most successful feeders.

The magnet public high schools on the newspaper’s list included the Baltimore Polytechnic Institute and Thomas Jefferson High School for Science and Technology, in Alexandria, Va.

Among Princeton’s top feeders was a public high school just down the road, where many of the university’s professors send their children. —Peter Schmidt

Update (12/31/2007): The Journal published a correction on December 28 saying that its analysis had omitted at least 20 high schools and had otherwise used incomplete data. As a result of its recalculations, its rankings have changed significantly. For example, the Daewon Foreign Language High School, in South Korea, is no longer ranked 13th.
