Research shows that school administrators' engagement is vital in creating a structure supportive of induction and mentoring for early career teachers. This article details a mixed-method research study that examined the role and impact of school administrators' engagement in four teacher induction programs in the United States (two statewide and two district-wide) supported by the New Teacher Center. The results identify administrator role expectations and participants' perceptions of the programs, and they indicate how vital school administrators' leadership and commitment are to a successful program. The article concludes with implications for theory, practice, policy, and further research.
