Proof School offers a transformative liberal arts education for kids who love math.

At Proof, students are immersed in a challenging and joyful school experience where they feel a deep sense of belonging.

Our courses emphasize exploration, problem solving, and communication. Students build a strong foundation in mathematics, literature, science, art, history, computer science, and languages. Our middle school curriculum is filled with hands-on and project-based learning; high school courses across all disciplines start at the advanced high school and introductory college level.

Community is core to who we are. With just over 100 students in grades 6-12, Proof School is a place where each student is known and each idea is heard. Founded in 2015, we have been growing alongside our students by listening, experimenting, and striving to make each year better than the one before.

Beyond the classroom, students have ample opportunity to discover new interests, pursue independent projects with faculty mentorship, and lead student initiatives. While we are not a school that can do everything, we are a school where nearly anything is possible.



Our mission and community principles define what it means to be a Proofnik.


Proof School offers a transformative liberal arts education to young people with an active curiosity and a passion for mathematics, equipping them to reason, communicate, and positively impact their world.

Faculty, Staff, and Board of Directors

Our school is built by the people in it.

Our teachers are intellectually vibrant, creative, and compassionate individuals who are united by a shared mission of nurturing our students. Supporting them are our trio of dedicated administrative staff. Our school leadership team oversees the daily learning environment of the school, while the Board of Directors steers the school’s long-term trajectory. 


Each year, we look for teachers who can grow with us. 

Teaching positions are structured to give teachers ample time to prepare for classes, respond to student work, and collaborate with colleagues. A standard teaching load totals 10 hours per week of class time, with an average class size of 12 students. Faculty participate in the full life of the school, from running clubs to mentoring students to engaging in outreach.

More details about current faculty openings are below.


California Law AB 500 requires schools to post policies regarding employee-student interactions, which is included here.





We embrace learning across the curriculum.

Our students come to Proof School as math kids. Where they go, and who they become, is discovered each year, in secondary school and beyond.

We are a school for kids who embrace and seek out challenges, who give deep consideration to their ideas and actions, and who look out for others. We aim for our graduates to lead in the world as analytical, literate, compassionate citizens. Our students are well versed in going to great lengths to seek out opportunities.



We have challenging academics, small classes, and a shared love for learning.

Proof School is a full-curriculum, liberal arts schools for kids who love math.

Across all seven years of middle school and high school, Proofniks engage in a breadth of disciplines to read and write critically, listen and speak intentionally, practice and experiment, and develop a fearless maker mentality. Along the way, students solve complex problems, take initiative, and pursue substantial projects. 

We offer content-rich courses in which students develop transferable skills, spanning literature and language arts, history and social science, art, science, computer science, and (of course) mathematics. We believe deep learning happens through actions and activities, whether that's tackling hard math problems together, analyzing ethics in literature class, or using power tools to build equipment for student-designed science experiments. 

With small classes, we are able to meet each student where they are, whether they need individual support or are hungry for challenges beyond standard school curricula. Our guides to middle school, high school, and mathematics coursework outline our approach to teaching and learning in the classroom, and includes representative course descriptions.


Our schedule makes room for immersive learning.

Courses take place across five academic blocks, each lasting six weeks.

Each year, students take four morning courses in humanities and sciences that span the entire year. These courses meet twice each week for 80 minutes per class period. These extended class periods allow students and teachers to explore, learn, and work in a substantive and sustained way. The block system enables classes to focus on an arc of content areas, key skills, and goals that build thoughtfully across the year, culminating in the year-end symposium for friends and families.   

Afternoons are devoted to math. An entire semester of learning happens within a single six-week block, giving students five semesters of math instruction each year. Our math courses emphasize inquiry with active engagement, and stress conceptual understanding alongside skill mastery. Actively working in class, in the company of a teacher and peers, makes it possible to successfully tackle challenging material.

Students receive substantial feedback in class, on their work, and at the end of each block, when teachers release ratings and rich narratives that describe a student’s academic achievement, disposition toward learning, and goals for the future. By focusing on just five courses at a time, and just three courses per day, our students are able to deeply immerse themselves in significant and meaningful learning.

Build Weeks, Flex Time, and Clubs invite students to explore, take deep dives, and build community.

Because flexibility is built into our schedule, we are able to extend learning beyond the classroom. 

We embrace time for curiosity, extended projects, and learning for the sake of learning. Each Wednesday, students participate in ungraded and unreported mini-courses and clubs on topics like photography, cooking, extended science labs, creative writing, web programming, and dance. We see these mini-courses and clubs not as supplements to the curriculum but as integral to creating a culture where learning beyond the conventional classroom is structured into the school experience.

In the week following each academic block, we pause our academic classes for Build Week. These themed weeks are devoted to the arts, math research, independent projects, field trips and overnight trips, and more—they give Proof School a sense of summer camp peppered throughout the year.

Build Weeks also give us time to reflect on our growth and goals, work on all-school challenges, play games that build community, and host annual events such as our school-wide AI tournament. A highlight of each year is Proof Camp, during which students can take the lead in designing activities for their classmates.
