High School

High School

The Leffell High School offers a structured yet flexible, integrated, concept-oriented curriculum. Our secular and Judaic academics are rigorous, and they are supported and enhanced by our values and ethics, our vibrant communal life outside the classroom, and the strong and lasting connections that are formed between students and staff throughout the high school years. All these components provide our students with the courage and confidence to self-advocate, persuade, and present their ideas and opinions in cogent and compelling ways as they prepare for college and beyond.

  • Small School, Big Options

    For a school our size, we offer a remarkable array of academic options. Beyond the core disciplines, our course catalogue highlights an ever-expanding list of elective classes in such areas as engineering and entrepreneurship, computer science, visual and performing arts, world languages, and physical education. And our partnership with the Virtual High School provides our students with access to hundreds of online course options.

  • Accelerated Courses and Individualized Program

    No two students at Leffell High School share the same academic schedule. Many students are drawn to our intensive honors courses, in such areas as the sciences, mathematics, and Judaic Studies. Our double-accelerated calculus program, for example, enables students to take the college-level Advanced Placement exam at the end of 11th grade. We also offer a rich network of support that prepare learners with a variety of academic needs to thrive. Most importantly, we are a single academic community, ensuring that the schedule provides opportunities for all students to learn with and from one another.

  • Individual Identity Formation

    High School is the time of life when students solidify the personal identities that will characterize them in their adult lives. In our classrooms, students are expected to define and articulate their own perspectives on the critical issues of our time, while being open to learning from viewpoints beyond their own. Judaic Studies courses in particular are built around this critical life skill of defining one’s own set of core ideologies while building community with others who may think differently. This ability, perhaps more than any other, prepares Leffell School students to thrive as leaders in the modern world.

  • Unique Senior Year

    The culminating experience of a Leffell School education is the transformative Lev v’Nefesh trip to Poland and Israel. Twelfth-grade students spend eight weeks walking in the footsteps of Jewish history, getting a taste of independent living, and learning from extraordinary guides and madrichim (counselors). Upon their return, under the guidance of a faculty member, seniors participate in either a student-designed capstone project or in an internship which provides them with work experience in an industry or field of their choosing.

Student Services

Our High School is proud to provide an enriching environment for students with a wide range of academic skill sets, strengths, and challenges. The Center for Academic Support (CAS) is designed to serve students who need extra guidance or structured support in order to thrive. Students enrolled in CAS are assigned a case manager who is trained in special education, and they attend a dedicated class with that teacher three times per week. The CAS specialist also manages individual learning plans, accommodations, regular consultations with each student's classroom teachers, and communication with families.

Beyond the Classroom

    • What truly distinguishes the Leffell High School is the seamless integration of a rigorous academic program with a robust student life outside the classroom.

  • Activities and Clubs

    So much of the vibrancy of High School life takes place outside the classroom, in student-led clubs and organizations. Our ever expanding array of clubs provide students with abundant opportunities to pursue passions, develop new interests, and exercise leadership. And each year, student leaders begin new clubs! Longstanding student groups include the Culture Club, which sponsors regular arts-related trips to NYC and elsewhere; the Garden Club, which operates its own organic garden; Midnight Run, which distributes clothing and supplies to people living on the streets; and the computer-programming and robotics teams.

  • Community Service

    The values of chesed (kindness) and gemilut chasadim (loving acts toward the community) are central to the Jewish tradition, and they lie at the heart of the mission of The Leffell School. Both the study and the performance of acts of chesed are included in the curriculum in each of our divisions, and High School students in particular are required to perform at least 40 hours of community service each year—with many performing dozens or even hundreds more than this. Many of our students have been honored by local organizations for being among their most dedicated volunteers. Click here to check out one of our sophomore chesed projects.
  • Shabbatonim and Class Trips

    Our alumni report that some of their most enduring memories from school come from the times that they spent together off-campus. Each grade spends joins together for one Shabbaton (Shabbat retreat) each year, celebrating joyously at a camp, at a hotel, or in Manhattan. And each year features a themed, multi-day class trip: the ninth grade goes on an overnight outdoor adventure for a dynamic group experience, the tenth grade goes to Washington, DC to work with the homeless population and lobby in Congress, and eleventh graders tour college campuses in a major northeastern city.
  • Athletics

    Our varsity and junior varsity athletics teams compete in the New York State Public High School Athletic Association. Click here to visit our athletics page.
  • Visual & Performing Arts

    In addition to our courses in studio art, theater, and instrumental music, our High School offers students numerous extracurricular opportunities to get involved in the arts. Each year students both perform and work backstage in our professionally-directed musical and a student-directed play. We are also very proud of our school band, string quartet, and award-winning a cappella ensemble. And student writers and artists produce an annual literary/art magazine, as well as a STEAM journal.
