How should we assess and present information about the quality of research-doctorate programs? In recommending that the 1995 NRC rankings "(Assessing the Quality of Research-Doctorate Programs: Continuity and Change) be updated as soon as possible, this study presents an improved approach to doctoral program assessment which will be useful to administrators, faculty, and others with an interest in improving the education of Ph.D.s in the United States. It reviews the methodology of the 1995 NRC rankings and recommends changes, including the collection of new data about Ph.D. students, additional data about faculty, and new techniques to present data on the qualitative assessment of doctoral programs. It also recommends revision of the taxonomy of fields from that used in the 1995 rankings.
