How this board is built
330 high schools publish a numbered matriculation list — where their graduates enrolled, counted, in the school's own School Profile or matriculation page. Every number on this page is copied from one of those documents.
Ivy+ means these twelve, named so you can check the arithmetic: Harvard University, Yale University, Princeton University, Columbia University in the City of New York, University of Pennsylvania, Brown University, Dartmouth College, Cornell University, Stanford University, Massachusetts Institute of Technology, University of Chicago, Duke University. A graduate is counted once, at the college the school says they enrolled at.
The per-class-year figure is the published total divided by the class years the document covers, so a one-year list and a five-year list can share a page. Where a school labels its own columns, the window comes from the column the counts sit in — a list headed "the classes of 2021-2025" whose first column reads "Class of '25" is one class year, not five.
College names are matched exactly as each school printed them, against the federal name or a curated spelling. A name that could mean two colleges is left out rather than guessed, so a count here can be lower than the count on the school's own page.
What absence means
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.
