In this study, the major hypothesis tested was: The chief administrators of higher adult education who respond to certain professionalization scales will have, on the average, a greater degree of professionalization in 1962 than in 1957 and in 1967 than in 1962. Each of the 12 variables related to Professionalization and Background Scales were analyzed in relation to the extent of Professionalization. The .05 significance level was employed throughout. None of the values obtained indicated significant change over time between groups tested. These findings were viewed as attributable, at least in part, to events which mitigated against further professionalization of the occupation. Such events included the expansion and diversification of the field of higher adult education and changes in the university setting and society between 1957 and 1967. Using a supplementary questionnaire, additional analyses which compared data from respondents and non-respondents to the initial questionnaire in terms of Professionalization and Background Scales scores, geographic location, and size of enrollment of program, were made. These analyses showed no significant difference between the groups of respondents and non-respondents. (Author/NL)
