MAI conducted a landscape scan designed to help youth-serving nonprofits translate their dedication to advancing opportunities for young people into data-driven insights and practices. This project involved surveying a national sample of youth-serving nonprofits to gather their practices and lessons learned about performance management and outcome measurement. Through analysis of organizational practices, data collection models, and in-depth interviews with a sample of these organizations, MAI led the development of a practical guide to assist youth development nonprofits, particularly those in workforce development and education, in developing specific, appropriate, and justifiable indicators of their effectiveness and driving continuous program improvement. The research illuminated that effective outcome definition is highly tailored to a program’s unique theory of change.
