Student learning outcomes assessment, when done right, is an ongoing and systematic process. Faculty and staff for leadership education programs often struggle to develop a comprehensive approach to assess the effectiveness of their programs, especially when those programs are offered through multiple modes of instruction. One department at a Midwestern public university has developed a thorough, five-stage process which any leadership education program can follow, regardless of size or method of delivery. This department considers three modes of instruction, including face-to-face on a traditional American campus, asynchronous online, and face-to-face at foreign universities via international partnerships. This manuscript describes the comprehensive process and offers readers considerations for implementation at their own institution.
