The purpose of this study was to examine the relationship between teachers' perceptions of their principals' servant leadership behaviors and teachers' organizational commitment. A sample of convenience was used and a total of (N = 175) teachers from the state of Texas at the (K-12th grade) level participated in this study. In addition to completing a demographic questionnaire, participants rated their principals' servant leadership behaviors as measured by the Servant Leadership Scale (SLS) and rated themselves on organizational commitment using the three constructs of organizational commitment which include affective, continuance, and normative commitment, as measured by the Three Component Model Employee Commitment Survey (TCM). A multiple regression analysis was conducted to determine if a relationship between servant leadership behaviors and teacher organizational commitment exists while controlling for teachers' age, gender, tenure, and highest level of education. Results showed a positive relationship between emotional healing and all three constructs of organizational commitment: affective, continuance, and normative commitment. In addition, results showed a positive relationship between helping subordinates grow and succeed and affective commitment. The results in this study also indicated that three of the four control variables were not predictors of organizational commitment. Age was a significant predictor of affective commitment (p < 0.05). Age findings were consistent with the literature. Overall findings revealed that there was a significant relationship that exists between the principals' servant leadership behaviors and teacher commitment. A discussion of the findings, implications and practical applications are provided. Additionally, the limitations, contributions to the scholarly knowledge base, recommendations for further research and key takeaways are included. This research study added to the literature to better understand how servant leadership behaviors affect teacher organizational commitment.
