This study evaluates the contribution of Extension-based community engagement design projects to development of core technical competencies and professional values in the landscape architecture program at Utah State University. Many university design programs—including landscape architecture—employ community engagement to address local and regional design dilemmas. Programs within traditional agriculture schools often frame these activities as contributory to their institutions’ land-grant missions. Engaged scholarship is well enumerated within the literature of landscape architecture. However, little has been published on how Extension facilitates these engagements or its contribution to development of core competencies and professional values. Utah State University’s (USU) landscape architecture program alumni and students were surveyed to determine their perceptions of Extension-based design projects’ contribution to development of core competencies and professional values. Results revealed projects contribute to development of core technical competencies including software skills, problem solving, as well as acculturation of professional values and interpersonal skills such as collaboration, empathy, and leadership. As land-grant design programs assess the value of Extension-based community engagement projects, this study illuminates benefits for developing core competencies and professional values in the next generation of design practitioners.
