School Overview

Building 21 sits in the Germantown/Ogontz area of northwest Philadelphia, a historically rich neighborhood with deep roots and a strong sense of community identity. The school takes a project-based, competency-driven approach to learning that appeals to families looking for something different from the traditional high school model — it's designed for students who thrive with hands-on, real-world work rather than standardized routines. Families drawn here tend to value innovation in education and are willing to invest time in understanding a non-traditional system that prioritizes student growth in ways that don't always show up in test scores.
