The high school that sends the most students to the University of Chicago is Horace Mann School
- Horace Mann School in the Bronx, New York sends the most students to the University of Chicago: 21.3 per class year, from a list the school labels "Class of 2024 - 2026 Graduates." That is first of 183 schools whose published lists name University of Chicago.
- Two Chicago schools come next, each at 18.0 students per class year. 2 of the top 10 schools are in Illinois, the university's own state.
- On the acceptances side, a separate list, Bronx High School of Science (The) is first, at 14.0 per class year.
A matriculation list is a list a high school publishes saying where its graduates enrolled. Per class year means the count the school printed, divided by the class years its list covers. That lets a one-year list and a five-year list share a page.
Horace Mann School ranks first. Its published list names 64 graduates at the University of Chicago. The school labels that list "Class of 2024 - 2026 Graduates," which covers 3 class years. That works out to 21.3 students per class year.

Two rows carry a note. Harvard-Westlake School labels its list "BY THE CLASSES OF 2021-2025," and the 14 counted here sit in a column headed "CLASS OF '25." Brunswick School labels its lists "Class of 2026 Matriculation; Composite Matriculation List of 2022-2026," and the 9 counted here sit under "Class of 2026 Matriculation."
The top 10 spread across six states. Connecticut has 3 of the 10. Massachusetts has 2. Illinois, the university's own state, has 2 of the top 10 schools. Those two Illinois schools are the pair ranked second and third. Each printed 72 students over four years.
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 count where students were admitted, not where they enrolled, so the two are never mixed. The acceptances lists are ranked on their own.
The full board carries the top 25 and the acceptances section. The University of Chicago page carries the college's own entry.
Boards as of October 2, 2026. Schools publish new lists every fall, so the live board is the current ranking.
