The 50 largest of 77 ranked private schools.

All schools, public and private, and the lists of colleges that admitted each school's graduates, are on the Claremont McKenna College feeder leaderboard. More about the college: Claremont McKenna College.

Each count is copied from a list the school published about its own graduates: where they enrolled, one student at one college. The ranked figure is that count divided by the class years the school's list covers. A school that is not on this page did not publish a numbered matriculation list we could read — that is all absence means here. It is never a statement about a school's graduates. Lists of acceptances (where students were admitted, not where they enrolled) are never counted in this ranking: an acceptances list runs about three times an enrollment list, so counting the two together would compare different things. Those lists are ranked on their own, separately.
