Several federal grants prioritized the role of community colleges in education and training in recent years, and one of the most substantial investments was the Trade Adjustment Act Community College and Career Training (TAACCCT) program of the United States Department of Labor (DOL). Beginning October 2011, these $2 billion capacity-building grants funded community colleges and their workforce and employer partners to prepare individuals for family living-wage employment that would in turn, provide skilled workers for industry sectors needed to recover and grow the economy. This brief is one in a series of four briefs that tell the story of how scaling and sustainability have happened under TAACCCT. The National STEM Consortium (NSC) is one of 23 Round One consortia and NSC is highlighted because the colleges within the Consortium have demonstrated success in scaling and sustaining change. In this brief, the story is told of what mattered most in the Consortium's efforts to sustain and scale transformative change. The content for the story is pulled from multiple sources including NSC published materials, the NSC Strategy Brief published by the Transformative Change Initiative (TCI), the evaluation reports published by Hezel Associates, the third-party evaluator (TPE) of the Consortium, and phone calls and in-person conversations with individuals from multiple community colleges that were part of the National STEM Consortium. Based on the team's research on change in the community college, seven guiding principles for scaling transformative change were identified. The National STEM Consortium addressed three key elements: (1) cross-Consortium collaboration to identify common goals and regional needs; (2) industry relevant curricula; and (3) expanded support for students, as important to the design and implementation of one-year certificate programs in five technical areas.
