Building 21 Allentown is a non-selective competency-based high school in the Allentown School District. It is a new secondary model that seeks to facilitate an authentic learning experience that will address the unique social and academic needs of all learners.

The Building 21 Allentown team will work closely with members of the local and school communities to carefully construct a robust network of online, offline, individual, small group, large group, skills-based, and applied learning opportunities to more effectively serve students of all types. Most importantly, the Building 21 model will develop teachers as guides and students as designers of their own pathways to graduation by giving them choice and voice about how, what, and where they learn.
