Teaching Approach

Updated 7mo ago

Proof School describes its teaching philosophy as a transformative liberal arts education for students who love math, centered on exploration, problem solving, communication, and a joyful sense of belonging. It emphasizes small classes, hands-on and project-based learning, inquiry-driven math, conceptual understanding alongside skill mastery, and sustained, immersive work across disciplines so students can pursue challenges, substantial projects, and intellectual curiosity.

Admissions

Updated 7mo ago

Proof School says families start by submitting an admissions inquiry through its portal; that step creates parent and student login credentials and leads to the rest of the application process with further instructions. (portal.proofschool.org) Applicants may apply for entry to grades 6, 7, 8, or 9, and students must be at least 11 years old by August 31 of their entry year; the school says it looks for students who genuinely love math, enjoy learning across subjects, and collaborate well with others. (proofschool.org) For timing, the public Apply page states that the deadline for the 2026–2027 school year has already passed as of March 19, 2026, while the portal FAQ says the "Apply" link is generally available from October through mid-January; a separate admissions-inquiry FAQ also mentions January 15, 2018, but that appears to be an older historical date rather than the current cycle. (proofschool.org) The site also says admissions are need-blind, there is no application fee, and financial-aid decisions use NAIS School and Student Services (SSS) data as a baseline. (proofschool.org) I did not find a public waitlist policy or any explicit admissions priority categories (such as sibling or legacy preference) on the website pages reviewed; the only related note is that the school particularly encourages applications from students of diverse backgrounds.
