The purpose of this study was to examine relationships between the job satisfaction of speech language pathologists (SLPs) and self-efficacy, work relationships and two components of job performance: teacher judgments of student improvement and supervisor ratings of teacher efficiency. It was hypothesized that each of the variables would be positively and significantly related to job satisfaction. No studies were found regarding individual factors of SLPs and their job satisfaction. Therefore, an investigation of this topic seemed practical and worthwhile. The research was conducted in urban school district in which 300 full time SLPs were asked to complete a survey questionnaire developed for this study. Quantitative and qualitative data were collected and analyzed from 119 respondents. Data were derived from a 5-point Likert scale used to determine if one or more of the variables could predict job satisfaction coupled with five open-ended questions to examined in-depth perceptions related to each of the variables. The quantitative analyses included a multiple regression and bivariate correlations. Results found that the hypotheses involving work relationships, self-efficacy, and the part of job performance concerning student improvement were supported. Qualitative findings determined themes on the importance of each variable concerning the job satisfaction of SLPs. However of three predictors, self-efficacy was considered the most popular. Implications for leadership discussed interventions to maximize work relationships and self-efficacy beliefs. Recommendations for future research included examining work relationships and other factors that may influence job satisfaction such as caseload size, the severity of the cases, job related stress and burnout.
