Job satisfaction remains a constant topic of discussion in teacher workrooms and a popular area for research across the United States. In the United States, teachers are plagued with various issues that seem to desecrate their level of job satisfaction despite notable attempts to improve our educational system. The purpose of this study was to determine whether there are differences in job satisfaction between private school teachers and public school teachers in Tennessee. The study utilized the Job Satisfaction Survey to collect 273 online surveys from teachers across Tennessee working in public and private schools. The data collected measured overall job satisfaction and attitudes about individual facets of job satisfaction, including pay, promotion, supervision, fringe benefits, contingent rewards, operating procedures, coworkers, nature of work, and communication. The data were also used to compare levels of job satisfaction between male and female teachers and teachers with varying levels of teaching experience. In an effort to explore the various levels of job satisfaction among male and female teachers, all experience levels, and the school type, the study analyzed the data with two-way ANOVAs and two-way MANOVAs. A significant difference was found in overall levels of job satisfaction between private and public school teachers, with higher levels of job satisfaction found in private school teachers. The data also showed a significant interaction between gender and school type, revealing that male private school teachers reported higher levels of job satisfaction than female private school teachers. A two-way MANOVA analyzed the individual facets of job satisfaction and their impact on male and female teachers in private and public schools. A total of 9 facets were examined throughout the study, but the only significant differences were found in supervision, coworkers, and nature of work. The findings of this study conclude that private school teachers in Tennessee report higher levels of job satisfaction compared to public school teachers. Private school teachers also report more positive attitudes in the areas of supervision, coworkers, and the nature of work. The overall goal of this study was to provide school leaders with data that may help improve job satisfaction for teachers by identifying what specific areas teachers use to determine their level of satisfaction. School leaders should consider initiatives that can be used to improve the areas of supervision, coworkers, and the nature of work and, therefore, improve overall job satisfaction.
