The problem with which this study was concerned was that of measuring and examining the level of job satisfaction among Texas high school band directors. The specific methodology included a quantitative comparison through confirmatory factor analysis of the factor structures of the sample of 109 Texas high school band directors and the norming population of 1460 industrial workers. There were two purposes for conducting the study. First, the relationships between an assortment of demographic variables and measured job satisfaction were examined. The second purpose was to measure the degree of fit of the Frederick Herzberg Dual-Factor Theory to the factor structure of the sample. Correlation, t ratio, and one-way analysis of variance were used to compare the demographic variables with measured job satisfaction. Confirmatory factor analysis through LISREL was used to examine and compare factor structures. Job satisfaction was measured with the Minnesota Satisfaction Questionnaire which was developed and tested through the Work Adjustment Project, Industrial Relations Center at the University of Minnesota. The twenty-item short-form retained the general reliability and validity measures of the 100-item long form. The Demographic Data Sheet is a researcher-constructed document used to gather data for use in classifying respondents by educational background, school classification, and out-of-Texas teaching experience. Respondents were also asked to indicate chronological age and number of years creditable teaching experience. Only when classified by educational background and school classification were respondents found to have significant differences in satisfaction scores. Those band directors who hold degrees in fields other than music have significantly lower satisfaction scores than those who have only music degrees. Directors from larger UIL classification schools have higher measured levels of job satisfaction than do those in smaller Texas schools. While there are strong similarities between the factor structures of the sample group and the norming population, the sample contained three distinct factors. The third factor, not identified in the norming population structure, was defined by the constructs of Social Status, Social Service, Authority, Ability Utilization, and Achievement. It was concluded that the Herzberg Dual-Factor Theory does not completely explain vocational adjustment among Texas high school band directors.
