Tuition & Fees

A GSB education is a significant investment in your child’s future.

Our students are talented, passionate, creative, and thoughtful and come from a diverse range of backgrounds, independent of financial circumstances. We encourage families who need assistance to apply for financial aid. Tuition assistance awards are available for eligible families.

GSB is a place where all students have the freedom and opportunity to explore their individual interests, gain new experiences, be strongly respected as individuals, have the support and mentorship of amazing teachers, learn to speak openly and freely to teachers as adults and to become the most complete version of their unique selves that they could possibly become.”

"The beauty of GSB lies in its commitment to creating an environment where children don’t just learn, they thrive. It's a place where they discover their strengths, embrace their uniqueness, and learn the importance of collaboration and community."
