Although many business schools seek to develop leaders and accreditation requires assessment of such objectives to document student achievement, the literature is devoid of leadership development approaches, learning objectives, or direct measures. Perhaps, this results from the perception that leadership is too amorphous or complicated to be defined and measured. This paper details the application of a critical relativist approach to define a graduate leadership learning objective, develop an analytic rubric to measure student achievement of that learning objective, and apply the rubric as both a course-embedded and summative measure to evaluate an interdisciplinary leadership minor’s program of study.
