Rankings
Which boarding schools send the most graduates to the Ivy+ twelve?
The Ivy+ board, filtered to the schools the TABS member directory lists as boarding.
Published, but not ranked
These schools publish a numbered list of where their graduates enrolled whose class-year window we cannot read as a span — "Since 2023", or a list with no class year printed on it. Their totals are real and are shown here; a per-class-year figure would be a number the school never published, so they are listed rather than ranked.
How this board is built
208 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.
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.
Boarding is read from the TABS member directory — The Association of Boarding Schools' 2026 list of its US member schools — matched onto our school pages by exact or town-confirmed name (173 of them). A school that directory does not list is not called a boarding school on a guess, so it waits for the next directory pass rather than appearing here.
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.
