What The Leffell School does
The Leffell School is a K-12 independent Jewish day school operating as a nonprofit organization in Westchester County, New York. Founded in 1966 as the Solomon Schechter School of Westchester and rebranded in 2013, the school operates two campuses spanning 50 acres: the Dr. Elliot Spiegel Lower School (K-5) in White Plains and the M. Mac Schwebel z"l Upper School (6-12) in Hartsdale. The institution serves approximately 700 students across kindergarten through twelfth grade, offering a curriculum that integrates rigorous secular academics with Jewish values education, Holocaust remembrance, and Hebrew language instruction.
The school's product portfolio includes the core K-12 academic divisions plus specialized high school programs such as the Independent Science Research (ISR) program — which produced the school's first Regeneron ISEF qualifier in 2026 — a Space Program, The Akiva Program, Reacting to the Past methodology, College Counseling, Arts, and Athletics (12 varsity sports). The flagship experiential offering is Lev v'Nefesh, an eight-week senior capstone experience in Poland and Israel providing Holocaust education and Jewish identity formation, operated in partnership with Israel Maven LLC and affiliated with ROOTONE. The school also holds unique historical assets including a Czech Torah scroll (Memorial Scrolls Trust #482, on loan since 1981) and a Polish-rescued Torah.
Revenue is generated primarily through recurring tuition charged to families, supplemented by charitable contributions through programs such as the Lions' Legacy Society and Dedicated Day of Learning. Financial statements are not publicly disclosed. The school distributes through a direct-to-consumer admissions model including campus visits, open houses, and inquiry forms, supported by community-based referrals within the Westchester Jewish network. Membership in PRIZMAH (Center for Jewish Day Schools) and NYSAIS reflects engagement with the broader Jewish day school and independent school ecosystems.
