About PSE

Our Mission

The Princeton STEM Expo (PSE) is launching as an inaugural individual mathematics competition dedicated to inspiring and empowering young problem-solvers. Taking place on Saturday, September 27, 2025, at Princeton High School, we believe that every student has the potential to excel in mathematics, and our competition provides the platform to discover, nurture, and celebrate that potential.

Competition Overview

PSE is a single-day individual mathematics competition designed specifically for elementary and middle school students (grades 3-8). Our competition challenges students with engaging mathematical problems while creating an environment where participants can test their skills and connect with peers who share their passion for mathematics.
