In understanding leadership to be the single most important factor in shaping a school’s performance, and second highest factor influencing student achievement, it is a necessity for investigations to focus on what successful leaders do to have excelling schools. Research has alluded to the understanding that the principal can no longer serve as the sole instructional leader of a school. This need for collaboration within the organization places a weight on principals to incorporate others within the school decision-making process. This study examined how collective instructional leadership is currently influencing teacher efficacy in high performing central Kentucky elementary schools. Data were collected through individual principal interviews and focus-group interviews to gain perspectives about how collective instructional leadership is currently influencing teacher efficacy, individuals involved in collective instructional leadership, and actions leaders engage in to promote individual and collective teacher efficacy. The findings of this study identified themes to support a hypothesis around how collective instructional leadership is influencing teacher efficacy. Through the finding of this study a working model of collective instructional leadership was developed. Findings indicate the four working dimensions within the collective instructional leadership model will help raise both individual and collective teacher efficacy within schools.
