This article reports on a 2-year qualitative research study of the processes by which middle school principals' policies and actions shaped the experiences of five novice teachers in two Michigan school districts. We examined beginning teachers' perceptions of principals' approaches to managing student behavior, instructional leadership, and teacher collaboration and their perceptions of the extent to which each principal was trusted by his or her teaching staff. At the end of the second year of data collection (2007-2008), all five beginning teachers expressed high levels of satisfaction and planned to remain teaching in their schools. We argue that leadership related to student behavior and instruction (as perceived by the novices), combined with high levels of teacher-principal trust (again as perceived by the novices), contributes to these outcomes.
