The Boston Foundation has long held education as one of its core strategic focus areas, aiming to strengthen the education-to-career pipeline and bolster pathways from early childhood through postsecondary completion for Boston residents. Intended to inform the Foundation's potential direction and activities related to science, technology, engineering, and mathematics (STEM) education in particular, this report examines Massachusetts Comprehensive Assessment System (MCAS) Science and Technology/Engineering test results for students residing in the city of Boston and enrolled in Boston Public Schools (BPS) and Boston-based charter public schools ("charters"). In so doing, the report begins to explore how prepared Boston public school students are to successfully pursue employment or postsecondary education in the STEM disciplines.
