  • School
On the cusp of adulthood, our high schoolers hone their gifts, commit themselves to others, and prepare to enter the great conversations of life.

That’s why we cultivate an environment of active engagement and purposeful exploration, so our students are prepared to thrive in the classroom, in college, and beyond. Students can shape their program and explore multiple opportunities for academic challenge in a curriculum that features advanced courses in nearly all disciplines. Combine that with our dynamic social landscape offering more than 75 student-run clubs and activities—it's no wonder GDS kids are multi-dimensional achievers and community members, self-starters and collaborators, athletes and artists, destined to excel as individuals and as agents of change.

Academic Highlights

  • Advanced study is offered across all disciplines, including the opportunity for independent study. GDS encourages all students to pursue their individual passions while exploring our diverse curriculum.
  • GDS is phasing out AP classes. We have committed to ending classes with the AP designation by 2022, in order to engage students in curriculum focused on authentic learning, cutting-edge research, and interdisciplinary explorations.
  • The Ninth Grade Seminar - Diversity and Equity: The Intersections of Identity focuses on identity and points of connections within groups. 
  • All seniors participate in a Senior Quest, or investigation, in which they apply their curiosity, talents, interests, skills, and knowledge to a question, task, creation, or issue of relevance to the student in particular as well as to a significant constituency outside of the GDS community. 
  • Each student benefits from a small group advisory, where they develop connections with students and their advisor. The advisor serves as the primary point of contact for the student and family on all matters.
  • The High School Innovation and Technology program offers electives catering to a wide range of abilities and experiences. These engaging, hands-on, challenge-based programs are designed to be meaningful, relevant, and truly fun. In GDS’s Maker Spaces and innovation laboratories, students self-direct, using both contemporary and traditional fabrication tools with the guidance of a High School Maker in Residence and computer science teachers. 
  • Our three full-time college counselors work with each GDS student to support them throughout the college process.
