School Notes

  • PERSONALIZED ATTENTION IN A CLOSE-KNIT COMMUNITY: At Knox, students are known by their teachers-not just by name, but for their strengths, interests, goals, and where they are ready to stretch. With a 6:1 student-teacher ratio, small classes, and personalized academic pathways, students receive the individual attention and challenge they need to grow.
  • COLLEGE READINESS & OUTCOMES: Preparation for college begins well before senior year. Knox students learn to think critically, ask thoughtful questions, collaborate, conduct research, and communicate with confidence. AP, Honors, and Dual Enrollment courses provide opportunities for greater academic challenge and college credit, while college counseling beginning in Grade 9 helps students plan purposefully for what comes next. Knox graduates achieve a 100% college acceptance rate and collectively earn millions of dollars in merit scholarships each year.
  • LEARNING BEYOND THE CLASSROOM: Some of the most important growth happens outside the classroom. Through athletics, the arts, clubs, service, and leadership opportunities, Knox students try new things, develop their talents, take on responsibility, and contribute to their community. With encouragement to participate rather than simply observe, students build confidence, resilience, and a stronger sense of what they can accomplish.
  • A GLOBAL, INCLUSIVE COMMUNITY: On our Long Island waterfront campus, students from neighboring communities and the New York tri-state area learn alongside boarding students from across the United States and around the world. Living and learning together exposes students to different cultures, experiences, and perspectives while creating the close personal connections that define the Knox community.
  • OPPORTUNITIES TO EXPLORE AND EXCEL: At a small school, students don't have to choose just one way to participate. A student can pursue advanced scientific research, exhibit original artwork, compete on an athletic team, perform on stage, ride in the equestrian program, and take on a leadership role. Knox gives students room to explore new interests while providing experienced students with opportunities to deepen their skills and pursue ambitious goals.

High School senior
This school is unique because of the tight-knit community. I had the best 4 years at this school and if I could go back in time, I would make the same choice again. I learned. . .

Class of 2023

Stony Brook
The sizes of classes are quite small, which I think is unique because it allows for more concentrated lessons and more one one-on-one teaching. The smallest class I've been to only had three other students. . .

Class of 2003

Fordham University
There is an amazing family atmosphere at Knox that is unlike any other school I attended. I highly recommend the school for any parent looking for a boarding school because your child will be cared. . .
