Most of the techniques that measure college enviromnments are based on student characteristics which are often confused with characteristics of college environments, thus producing many problems for subsequent investigations of college influence. One such technique is the Environmental Assessment Technique (EAT), which describes the environment in terms of 8 characteristics of the student body (size, average intelligence, and 6 "personal orientations) based on the proportion of graduates who majored in each of 6 classes of major fields. To assess graduate school environments, a modified EAT was used which groups graduate faculty and curriculum into 6 classes of major fields and assigns 4 representative disciplines to each type of field. Data were collected from 87 graduate school catalogs for 1968. Curriculum, faculty, and degrees awarded were converted separately to 6 normalized standard scores which comprised a profile for each institution. The profile scores measured the graduate school environment without using student characteristics, and represented fairly stable characteristics of the institution. They were related in plausible ways to other measures of university environment, and were meaningfully related to the quality of graduate education. The modified EAT technique therefore seems to have potential for studying graduate school environments and the impact of graduate schools on their students. (WM)
