This study of graduate and professional school students attempted to find out how students enter graduate and professional school and to assess their reactions to their experiences there. Following an introduction, the report includes: (1) a description of the sample students and how their current activities were related to their plans as seniors, (2) an account of variables affecting the rate of attendance, (3) an account of various influences on the students' attendance, as assessment of their activities and their descriptions of their schools' environment and professors, (5) an evaluation of student reactions to their schools, (6) students' reactions to some proposed reforms in advanced education, and (7) a comparison of the experiences of men and women and of blacks and whites. Also considered were the special characteristics and reactions of scholarship recipients, older students and married students. Conclusions about the meaning and significance of the findings for each field were drawn. Also included are a six-page bibliography, two appendixes, predictor variables list, a college graduate survey form, and a college senior survey form. (Author/BP)
