This qualitative, observational-case study examined teacher efficacy and its influence on classroom management when teaching African American males in grades PreK-2, through the lens of choice theory (Glaser, 1998). Data was analyzed with the intent of gaining an in-depth understanding of how teacher efficacy influenced classroom management when addressing the needs of survival, power, freedom, fun, and belonging of African American males in grades PreK-2. Through the use of professional development, the intended goal was to discover insight on how to better assist teachers in supporting the social and emotional needs of their African American male students in grades PreK-2. The researcher expected to find a relationship between classroom management and teacher efficacy, when considering the influences of various elements such as professional development, teacher bias, the availability of educational resources, and cultural awareness. Data were collected from pre-and post-professional development responses, as well as from observations. Research was conducted in a suburban Illinois school district, located on the outskirts of a major Midwestern city. The participants included 10 teachers whose classroom population consisted of five or more African American male students in grades PreK-2. Using the comparative analysis design, teacher pre-and post-professional development responses were compared to one another. Findings revealed that teachers who understood how to fulfill students' needs of survival, power, freedom, fun, and belonging, through the use of professional development, were able to identify, create, and implement appropriate classroom-management strategies, which were directly tailored to the needs and abilities of their African American male students.
