Mathematics pathways are a promising approach for improving student outcomes, but if implementation happens one college at a time and without statewide policy support, the potential for scaling is diminished. This report describes the structure of the MPC project and the supports that the Dana Center is offering to participating states. In addition, drawing on 33 semi-structured interviews with mathematics faculty, state-level leaders, and technical assistance providers across the six states, this report explores the question: What state-level structures, conditions, and processes facilitate statewide implementation of mathematics pathways?
