This commentary on assessment training in scientist-practitioner and practitioner-scholar programs examined potential differences between these training models on assessment instruments included in the curriculum, assessment instructors, modes of interpretation, anticipated clients, and service delivery styles. Over time it appears that the potential for difference in assessment training inherent in Boulder and Vail model values has been minimized. If these models for training professional psychologists are to be effective in preparing students for assessment tasks with additional populations of consumers in new service delivery systems, attention to these potential differences in assessment training offers promise for more responsible and competent practice in a democratic society.
