"The first problem that Mr. Bowen, Mr. McPherson and the book’s third author, Matthew Chingos, a doctoral candidate, diagnose is something they call under-matching. It refers to students who choose not to attend the best college they can get into. They instead go to a less selective one, perhaps one that’s closer to home or, given the torturous financial aid process, less expensive.
"About half of low-income students with a high school grade-point average of at least 3.5 and an SAT score of at least 1,200 do not attend the best college they could have. Many don’t even apply."
