Successful and high achieving schools have leaders that establish clarity within the school and know they "have a hand in shaping events" and results they want to achieve (Bandura, 2012, p. 11). Successful and high achieving schools not only implement specific research-based practices that help all students succeed, but they also identify and implement key behaviors and mindsets that provide clarity in making these practices successful (Canfield, 2015; Covey, 2004; Senge, 2006). This three-article dissertation addressed the research question: How do behaviors and mindsets support self-efficacy of individuals on leadership teams in the selected Midwest charter schools? The researcher constructed a grounded theory of behaviors and mindsets that support self-efficacy using qualitative study methods and techniques of social constructivist grounded theory.The first article describes behaviors that support self-efficacy from the dimensions of habits, responses, and actions and mindsets that support self-efficacy from the dimensions of thoughts, outlook, and self-perceptions. The second article identifies mastery experiences, vicarious learning, social persuasion, and affective states (Bandura, 2012) as the ways individuals develop and sustain their behaviors and mindsets. The third article focuses on how individuals on leadership teams in the selected Midwest charter schools ensure they are implementing the behaviors and mindsets that support their self-efficacy.The significance and implication of constructing a grounded theory of behaviors and mindsets that support self-efficacy is that leaders need to be the change they want to see in others (Covey, 2004) and when this occurs, people change an organization (Covey, 2004; Fullan, 2016; Senge, 2006).
