The context of this self-study is a professional development project involving primary-grade teachers in one public school and two university teacher educators. The authors are two teacher educators who are both former public school elementary-grade teachers.The aim of this self-study was to illuminate their understanding of their own professional identities as teachers. Analysis of their narratives revealed that fundamental aspects of their teacher identity have remained constant as their careers have evolved. Regardless of the setting, the age of their students, or the expanded expectations of the university to engage in research and professional service, the authors are, first and foremost, teachers.
