The mission of BPE is to drive exceptional outcomes for all students by developing great teachers and great schools. For three decades, BPE (formerly the Boston Plan for Excellence) has devised solutions to the toughest challenges faced by Boston’s students and teachers by weaving together expertise in teacher training and school development. We believe ambitious teaching (which we define as instruction that consistently engages all students in rigorous content) requires not only effective teachers, but also systems that support great teaching and methods for continuous improvement. We have prepared over 700 teachers for Boston's public schools through the nationally recognized and replicated Boston Teacher Residency (BTR) program, and we have pioneered scalable, cutting edge data tools and whole school improvement strategies. We also created the Dudley Promise Corps (DPC) to leverage the power of national service to expand learning time, engage families, and provide extra support to students in the Dudley neighborhood.
