The purpose of this qualitative case study was to develop an understanding of how current and former middle school teachers in a suburban school district in northeast Georgia perceive low self-efficacy impacts their classroom management style. The theory guiding this study was Bandura's (1977) self-efficacy theory as it supported the idea that self-efficacy can determine how one approaches a task, goals, or challenges. Data were collected using a survey, interviews, questionnaires, direct observations, and a focus group. A collective case study approach was used to conduct a holistic analysis to provide detailed descriptions of the themes and patterns that exist across the cases. Four themes emerged from the data analysis process: build relationships, be flexible, convey expectations, and make a difference. The themes were consistent with the relevant literature regarding teacher self-efficacy and classroom management and provided answers to the three research questions proposed in the study.
