Although touted as beneficial to student learning, cultures of assessment have not been examined adequately using validated instruments. Using data collected from a stratified, random sample (N = 370) of U.S. institutional research and assessment directors, the models tested in this study provide empirical support for the value of using the Administrators' Survey of Assessment Cultures as an assessment tool. The resulting first order model provided good fit statistics and included five factors: a) Faculty Perceptions, b) Use of Data, c) Sharing, d) Compliance or Fear Motivators, and e) Normative Purposes for Assessment. Internal consistency estimates were also good (Cronbach's a = 0.792 to 0.922). Use of the Schmid-Leiman solution afforded further support for the higher order factor, Culture of Assessment. Predictive discriminant analysis correctly classified the majority of the respondents (80.7%) as belonging to a student learning or accreditation group based on the linear classification scores. Implications for assessment leadership, practice, and future research are offered.
