In alignment with the National Art Education Association's (NAEA) 2015-2020 Strategic Vision, Enid Zimmerman conducted an evaluation of Summer Vision DC (SVDC), an NAEA-sponsored, museum-based art education professional learning community program. The purpose was twofold: to provide feedback to the leaders of the program (including Renee Sandell, program director), and to create a model for art education leadership programs in school and museum settings. Background information about the program is followed by a description of the evaluation design and research process, including a conceptual framework, data analyses, interpretations of an online survey and focus group meeting, and feedback from the program leaders. We conclude this study with explanations about the impact of the program and revisions and outcomes that were initiated to reinforce quality leadership in a professional learning community. We offer recommendations for further professional development using the SVDC leadership model for developing personal, collaborative, and public voice that can take place in diverse educational contexts.
