The 50 largest of 66 ranked private schools.

All schools, public and private, and the lists of colleges that admitted each school's graduates, are on the University of California-Santa Cruz feeder leaderboard. More about the college: University of California-Santa Cruz.

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.
