Local leaders are essential for helping Michigan achieve its 30-year water strategy goals. The Michigan Water School is an Extension nonformal educational program to address the knowledge gap of local leaders. We evaluated programs conducted from 2017 to 2019. Results revealed program outcomes in knowledge, attitudes, perceptions of criticalness to work, and stewardship and behavioral intentions aligned to water quality, water quantity, and field experience units. Growth areas for program improvement include water policy, economics, planning, and finance as well as expanding the focus of the program for transformational leadership and to broaden recruitment efforts.
