This rubric was developed primarily from the 1976 Inventory of the same name by Dr. Brent D. Ruben, of Rutgers School of Communication (retired), filtered through the lens of the Developmental Model of Intercultural Sensitivity (Bennett, 1986). It allows an observer to categorize or "grade" behavior that indicates: respect, openness, empathy, tolerance of ambiguity & posture towards authority. This HubICL tool comes with a lesson plan.
