Grades 9-12


Upper School students embrace intellectual adventure, academic challenge, and social responsibility. Meaningful experiences guide and develop a sophisticated understanding of concepts, creative confidence, community connections, an independent voice, and social impact.

Action

“I hope that I can transform all of these lessons, ideas, and thoughts into action, and that I can, just as every speaker at Global Week, make my mark on the world.” Riya B. '18

Collaboration

Collaboration occurs in many forms and with many people - in class, on a team, on the stage, in so many unexpected ways all to create something new.

Research

With academic curiosity as a driving force, students choose topics, generate researchable questions, and develop seminal inquiries that guide discovery and self-expression.

Communication

Senior speeches, Founder's Day, questions during symposia, in every classroom; clear communication is what we do!

Critical Thinking

More important than having an answer is the ability to examine your thought process and understand how you came up with the final result.

Creation

Making art allows students to embrace imagination, helping them see beauty everywhere, and to become mindful, inquisitive, and empathetic.

Innovation

“Seize this chance. Use it. Enjoy it. Fail miserably and get angry about it. Maybe the pleasure isn’t in succeeding. Maybe the pleasure is in the possibility of success.”rekha R. '18

In the Company of Girls

“There’s an underlying sentiment of acceptance, an acknowledgement that you fit in with your surroundings that evokes a sense of comfort.” Sara Z. '18

Engagement

“At Castilleja, everyone genuinely cares that you care about things; that you’re willing to take a stance, whatever that stance may be.” Sara B. '17
