School Overview

Building 21 Allentown is a newer, project-based learning school in the heart of Pennsylvania's third-largest city, designed for students who thrive outside of traditional classroom structures — think real-world problem-solving over standardized worksheets. It tends to attract families who are open to an alternative approach to education and want something different from the conventional high school experience. Allentown itself is a gritty, diverse, and culturally rich city in the Lehigh Valley, with a strong Latino community and a downtown that's been steadily reinventing itself, making Building 21 a fitting reflection of a city that's also figuring out its next chapter.
