The Knox School, founded in 1904 by Mary Alice Knox, is the oldest private school on Long Island in New York. As a co-educational boarding and day school for grades 6-12, Knox prioritizes the overall well-being of every student. With small class sizes, students receive individual attention that nurtures their education.

Our dedicated educators go beyond the classroom, serving as dorm parents, advisors, coaches, and mentors. At Knox, everyone is family. We offer the highest levels of academic, artistic, and athletic programming, including Advanced Placement classes and dual-enrollment courses for college credit.

Our STEM lab provides students with opportunities to explore technology, computer science, and engineering. Many of our educators are also college professors, ensuring the highest levels of instruction and expertise. But Knox is more than academics.

We foster character development and global citizenship in our students through daily living of our core values. Respect, Responsibility, Integrity, Courage, Kindness, and Scholarship are infused in every aspect of our community. For over a century, The Knox School has been changing student lives.
