Assessment culture is a subset of organizational culture defined by the values, beliefs, and assumptions held by its members. In higher education, a positive assessment culture is characterized by trusting relationships, data-informed decision-making, a respect for the profession of teaching, and an internally-driven thirst for discovery about student learning. Positive assessment culture generally connotes the existence of conditions for collaboration among practitioners, reward structures, professional development opportunities for faculty and staff, student involvement, and a shared commitment among leaders to making institutional improvements that are sustainable.
