What families are also choosing at a private school

Parents are not only shopping for college outcomes. The tables above count where graduates enrolled, and a high school is also four years of a teenager's days: who they spend them with, what the school asks them to value, and whether the adults know them.

• Community and values fit. A private school sets its own mission and expectations, and the application, the entrance exam and the interview work as a fit signal in both directions. On the federal Private School Survey, 9 of these schools are Catholic, 4 have another religious affiliation and 15 are nonsectarian.
• Class size. Class size is a fair question for each school's admissions office; we hold no student–teacher ratio for the schools listed here.
• Advising. Each private school builds its own college-advising model, so the useful question is how many students each counselor carries and how early the work starts.
• Arts and athletics access. A smaller school can mean more students on each team and in each production; ask each school what participation looks like.

Public schools are a great choice when a family cannot afford a private school, and a published college list is one of the few outcome measures a private school and a public school can be read on side by side.

Other metros are on the private high schools by metro index. The same arithmetic across every state is the Ivy+ enrollment board; for one college at a time, see which private schools send the most students to each college.

Ivy+ means these twelve: 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 school's own document covers, and both are shown. 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. Grades and religious affiliation are from the National Center for Education Statistics' Private School Survey. 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. A school is listed here when its NCES coordinates fall within 22 miles of the metro's center and it is in CT.
