Understanding teaching as a political act is often assumed to be a strength for teachers; however, this assumption conceals important aspects of their processes of becoming politicized. I argue that seeing teaching as a political act can be a liability for prospective teachers of color who engaged with college student activism if these assumed qualities are not productively addressed in teacher education programs. I examine trajectories of change in a prospective teacher's sense-making about activism over the course of her first year in a master's and credential program and explore the implications of these findings for programs of teacher education.
