A study was undertaken, in 1976 and for the three following years, of adult students in Australian higher education. The study examined: (1) the phenomenon of adult students and the extent of their involvement in higher education; (2) the politics and practices of institutions towards these students; (3) staff attitudes in the courses; (4) adult student characteristics; (5) why these students came to higher education institutions; (6) their problems, costs, and benefits; and (7) their success as students. In some cases these issues were examined at the national level, and in some cases at the local level, using Monash University as a case study. The results of the study are presented in some detail, with extensive data tables and narrative analysis. It is noted that there are two broad groups of mature age people entering higher education--those needing re-certification and those re-entering the academic world--and that the needs of these part-time students must be put into an institutional perspective. The staff survey instrument is included. (MSE)
