Institutional cultures of assessment are praised as beneficial to student learning. Yet, extant studies have not explored the theoretical foundations and pragmatic approaches to shaping cultures of assessment. The researchers used the Delphi method to explore 10 higher education assessment leaders' attitudes and theoretical perspectives regarding cultures of assessment. These expert assessment leaders were iteratively surveyed until a reasonable threshold of consensus was reached. Study participants viewed "buy-in" as a necessary component of a positive campus culture of assessment, and advice on reshaping negative cultures was offered. Assessment leaders' guiding theoretical frameworks were implied and loosely defined with metaphors. Finally, advice is offered for improving cultures of assessment by symbolically connecting assessment to student learning through dialogue.
