Greenwich Country Day School – Upper School

The GCDS Upper School is a transformational high school. Built on the nearly 100-year foundational values of GCDS, students engage in deep, joyful learning. 

At GCDS Upper School, students are both consumers and creators of knowledge. Under the guidance of an extraordinary faculty, they find natural connections between traditional subject areas and apply their learning to investigate areas of interest in greater depth, solve problems, and innovate. 

At the GCDS Upper School, learning springs from inquiry, the pursuit and application of deep content knowledge, and the challenge of analyzing and solving complex problems with real-world impact. Our program cultivates learning and achievement in a community that fosters joy, personal connection, inclusivity, and the genuine belief that each student has a unique and valuable perspective to offer.

Our program builds character and skills in pursuit of independence, purpose, and excellence. Our 1:6 faculty/student ratio, our commitment to teaching excellence, and our research-driven curriculum foster powerful and collaborative student-faculty relationships grounded in mutual respect and trust. This culture is the foundation for educational achievement: students at GCDS realize they have power to affect change, to take responsibility for their own learning, and to develop an enduring sense of belonging and ownership in their community.
