<p>The AGEP-NC Alliance for Graduate Education and the Professoriate developed, implemented, and studied a model for creating institutional and departmental-level change to promote degree completion and preparation for faculty careers of Black, Latine, and Indigenous American doctoral students in science, engineering, and mathematical sciences. The AGEP-NC model has, at its core, cohorts of faculty fellows who serve as knowledgeable catalysts for change. Thirty-four departments at three institutions: a predominantly White (PWI) Research I land grant, an urban research PWI, and a historically Black land grant university, participated in the alliance. Each participating department was charged with developing a plan for promoting the success of diverse doctoral students and reporting annually on progress. Twenty-nine participating departments have drafted and started implementing plans and 14 have formally adopted plans. As part of the evaluation, faculty were surveyed at the beginning of their department’s participation in the project and again two years later. The faculty fellows were also interviewed at the end of the five-year project. Using these data, the department plans, and reflections of the faculty fellows, we report on changes in faculty attitudes and action items adopted by the two institutions with implemented department plans and sufficient survey response data for analysis. The changes made include (1) increased student funding; (2) new or revised courses and course materials; (3) enhancements to advising, orientation, and student handbooks; (4) community-building activities; (5) mission statements and revised faculty evaluation criteria; and (6) training to enhance faculty skills for culturally responsive mentoring.</p>
