Many institutions of higher education develop assessment systems to demonstrate evidence of value added and to meet accreditation requirements. The sustainability of such assessment systems is usually dependant on creating a culture of assessment, which entails establishing shared values and principles and implementing practices designed to meet organizational goals. A survey of 119 assessment professionals revealed both the challenges and facilitating factors in creating and sustaining a culture of assessment. This article presents the survey results organized by an institution's stage of development in establishing a culture of assessment: beginning, progress, or maturation. The article also provides specific examples to help institutions move along the continuum or improve their current practices and concludes with a discussion of policy implications.
