As a parent from China, what sets Knox apart for me is the heartfelt passion radiating from every teacher. This dedication shines through in everything they do: not only within vibrant classroom lessons, but woven into the design of every school event. Students are supported to spark curiosity, nurture boundless imagination, and cultivate a deep love for the world. My son has been empowered to find his unique pathway to exploration—his strengths and talents aren't just recognized, they're encouraged to shine."
