A Message from the Head of School

Greetings! You are about to make one of the most important decisions of your lives – choosing a private school that will provide you with the best opportunities for success in college and beyond. 

Founded in 1904 by Mary Alice Knox, The Knox School is the oldest established private school on Long Island, in New York. Today, Knox is a co-educational boarding and day school for grades 6-12 where the total well-being of every student is our top priority.


At Knox, everyone cares and knows your name. Small class sizes allow students to receive the individual attention they deserve when investing in a private school education. Our dedicated educators know students beyond the walls of the classroom and serve as dorm parents, advisors, coaches, and mentors. Knox students are well-cared for in our supportive environment where everyone is family.

At Knox, every student’s potential is unlocked and maximized. 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 is a gathering place for students to explore technology, computer science, and engineering. Many Knox educators are also college professors, which guarantees that our students receive the highest levels of instruction and expertise. Athletics are part of students’ daily routines to promote both physical and mental health after an intense day of coursework. 

At Knox, every student is inspired to go higher. Beyond academics, arts, and athletics students and staff work together to build character and become responsible, global citizens. Our school community lives daily by the core values of Respect, Responsibility, Integrity, Courage, Kindness, and Scholarship, and our graduates bring these values with them when they leave the gates of our campus after high school, ready for every challenge that lies ahead. 

The Knox School has been changing student lives for more than a century. With endless opportunities rooted in a tradition of educational excellence, your choice should be clear by now. Since “seeing is believing,” we invite you to come to our campus, feel the vibe for yourself, and let us help you make one of the most important decisions of your life – to choose Knox!

Semper ad Lucem,

Virginia Riccardi
