Biographical and professional information for all 168 faculty members employed at the 35 largest graduate centers for science education was collected and analyzed. This is a report of the analysis and a discussion of the implication for the profession. The graduate faculty at major U.S. centers is homogeneous as to age, sex, rank, academic preparation, previous experience, research productivity, and professional involvement. The stability (or slight decline) in number of new personnel employed at research centers, and the multipurpose features of most centers are viewed as major problems. There are few examples of cooperative efforts among the 168 and few examples of clearly defined research efforts over an extended period of time.
