About Cambrian Academy
Cambrian Academy is a private independent school in San Jose, CA serving students in grades 6–12. With only 84 total students enrolled, it is one of the smallest private schools in Silicon Valley — and that small size is its defining characteristic. The school operates on a guide-led model where teachers function as facilitators and mentors rather than traditional lecturers, supporting students in taking ownership of their own learning.
Cambrian Academy has earned The School Navigator's Future-Ready badge for meeting 3 of 5 criteria: project-based learning curriculum, an 11:1 student-teacher ratio (well below the 15:1 threshold), and guide-led instruction as the core instructional model. The school describes its mission as developing confident, independent learners prepared for a world that traditional lecture-based schools may not adequately address.
Tuition is approximately $18,000 per year — significantly below the San Jose independent school average of $22,348/yr, and less than half the tuition of The Harker School. The school is particularly strong for students who felt overlooked or invisible at larger schools, students who are transitioning between school systems or countries, and students who need more personalized pacing.
