Despite numerous studies and reviews on faculty turnover, there appeared to be no systematic investigation of factors which influenced voluntary turnover among full-time faculty members in Nigerian educational institutions such as those studied here. In addition, it appeared that Nigeria lacked faculty turnover data for use in any meaningful research study. Therefore, this study investigated factors perceived to be influential among full-time faculty members leaving their jobs or institutions voluntarily. The six facets of the Job Descriptive Index developed by Smith, Kendall, and Hulin as well as a questionnaire about commitment development by Mowday, Porter and Steers elicited data concerning: present work, pay, promotion, supervision, coworkers, job in general, and commitment. Two hundred and eight (84.21%) of 247 full-time faculty members from ten selected colleges of technology/polytechnics in Nigeria became involved in this study. Means, frequencies, percentages, one-way ANOVA set at .05 level and Scheffe Test of Multiple Comparison set at .10 level were used for the analysis of data. Based on the findings, it could be established that full-time faculty members in Nigerian Colleges of Technology/Polytechnics are dissatisfied with their conditions of service. The most influential factors for voluntary turnover were pay and opportunities for promotion. Conclusions drawn from the study indicate that the demographic characteristics (gender, age, level of education, years of college teaching experience, salary grade level, college/polytechnic of employment, and region of origin) affect full-time faculty members' work attitudes. Further studies are recommended to determine policies and practices suitable for retaining the most capable full-time faculty members in Nigerian Colleges of Technology/Polytechnics.
