Adelphi Academy

What Adelphi Academy does

Adelphi Academy of Brooklyn is a private, independent, coeducational, college-preparatory day school operating a single campus at 8515 Ridge Boulevard in the Bay Ridge neighborhood of Brooklyn, New York. Founded in 1863, it is the oldest private, independent, continuing, coeducational, college-preparatory day school in Brooklyn, enrolling students from approximately two years of age through twelfth grade across Early Childhood, Pre-K For All, Lower School, Middle School, and Upper School divisions, with supplementary programs including Project Succeed and the International Scholars Academy. The school operates with an 8:1 student-teacher ratio, is a New York State Regents Exempt Program, is chartered by the Board of Regents of the University of the State of New York, has been accredited by the Middle States Association of Colleges and Secondary Schools since 1928, and is a founding member of the Coalition of Essential Schools.

The curriculum is supplemented by an extracurricular portfolio including The Adelphi Oracle student newspaper, The Adelphic yearbook, The Adelphian art journal, Theater Arts, athletics, a Journalism Club, a Student Advisory Board, and a Driver Education Program delivered on campus through a partnership with Autonautics International Driving School. Princeton Review operates an SAT/ACT test-prep program on site, and Park Slope Day Camp runs a summer program using Adelphi facilities. The school reports a 100% college application, acceptance, and attendance rate.

The business model is tuition-funded: families pay recurring annual tuition for educational services, with additional revenue from ancillary fee-bearing programs such as driver education and summer camp. Pricing is not publicly disclosed; families are directed to inquire directly. The go-to-market is community-led, anchored by the school's 160-year reputation in Bay Ridge, and amplified through organic social media (Facebook, X, Instagram, YouTube) and the Panther Press Room content hub. The school is independently operated under Head of School Ms. Iphigenia Romanos, with no disclosed parent company, institutional investor, or external ownership.
