Upper School


An Expansive Adventure

Schools that urge high school students to follow the expected path, check only the right boxes, and polish their resumes are failing our students -- and breeding stress and anxiety.

At King School, we set a better standard by encouraging students to see learning as a personal adventure; one without a defined beginning, middle, or end. Our students engage deeply with the experience of education -- not just mastering material, but also inviting collaboration, applying knowledge, and making unexpected discoveries.

A Better Standard for Upper School

When young adults are cheered on as they begin to take ownership of their ambitions and achievements, they feel like stars of a team designed and built for their drive for excellence. As a private high school located in Stamford, CT, King school empowers students to unleash their greatness by emphasizing self-knowledge, expansive learning, and courageous thinking -- the very qualities that lead to happy, healthy, and purposeful lives.

"It’s fascinating to learn the stories of others, and how aspects of people's experiences have come to formulate what they believe. To me, there's always something to be learned from every person and their experiences."

US Students Embody King's Virtues during Prize Day 2021

At King, excellence occurs in a community context. On Prize Day, we called out individuals' names as embodiments of excellence, but the fact is that no one can achieve anything alone. "Teachers, classmates' comments or debates in class or in study groups or teams, great assignments, careful coaching - this is what supports excellence. We all call on each other to see excellence, and we at King never stop seeking it. One of King's Virtues is perseverance, and we believe that this virtue, in particular, is alive and well," says Head of Upper School Marnie Sadlowsky. Congratulations to all of our Recipients this year!
