This mixed-methods study is a teacher-initiated, collaborative inquiry involving a professional development school (PDS) and a university. The examination focused on teachers’ perceptions of teacher retention and mobility at their PDS. Participants were 134 teachers at a large, suburban elementary school in the southeastern United States.The findings clustered around two primary dimensions: (a) congruency of teachers’ beliefs and practices with organizational norms and (b) teachers’ relational needs and administrators’ willingness and ability to meet such needs.
