Building 21 is a nonprofit organization that is reimagining secondary schooling to meet the needs of all learners.

How We Work

Building 21 partners with school districts to design, launch and operate innovative schools. Our schools are afforded significant flexibility and autonomy by our district partners to pursue our vision for student and adult learning. Our schools are measured against the same accountability systems as other public schools, and our teachers are all members of the local teachers’ union.
