The purpose of this study is to explore the writer identity of four preservice teachers from a large midwestern University. I utilized the narrative inquiry methodology. I interviewed participants four times: Once in January 2019, January 2020, March 2020, and May 2020. I also asked participants to submit a visual metaphor and reflection. Additionally, I observed participants teach in the secondary classroom. Primarily, the findings reveal that participant writer identities largely influence their secondary writing pedagogy. The findings also indicate that participant writer identities were strongly influenced by their k-12 English teachers. Lastly, the findings suggest that participants experienced trouble navigating tensions in writing instruction. The implications suggest that teacher educators can highlight identity work in teacher education courses to strengthen writer identity. Similarly, I recommend in the Implications section that teacher educators design activities to strengthen preservice teachers' writer identities so they can strengthen the writer identity of future secondary students. The implications also underscore how teacher educators can highlight the tensions that preservice teachers may encounter as a secondary writing instructor, and how to navigate such tension. This study complements the research on writing teacher education and provides new possibilities to effectively prepare writing instructors.
