At our intentionally small 612 school in Santa Cruz, students are known not just by name, but by heart.
With an average class size of 12, Kirby offers a learning environment built on trust, depth, and connection-where teachers don't just teach; they challenge, guide, and believe in every student.
Here, intellectual rigor and emotional belonging go hand in hand.
Our college preparatory curriculum is inquiry-driven and human-scaled-designed not just to check boxes, but to cultivate thinkers, creators, and contributors who can navigate complexity with confidence and care.
We serve students who are curious, capable, and courageously themselves.
They learn to ask big questions, take meaningful risks, and lead with integrity-not because they're performing, but because they're becoming.
At Kirby, students don't just prepare for college. They prepare for a life of purpose.

School Reviews

My son's teachers have all been attentive and are genuinely excited to teach. They provide insightful feedback about my son's opportunities and challenges, allowing me to be proactive at home if needed to support. Progressive and respectful community. Incredibly small class sizes where no one can be invisible. The dialogue that happens in class spills over at the dinner table. I've never seen my son so interested in what he's learning and so interested in exploring what he's learning with others. Academically challenging but with lots of support if needed. My son is doing things I never imagined he'd be interested in -- with a new found identity in being involved in those activities. Highly recommended.
