I present a two-year case study of one pre-service teacher (PST), Johnny, as he moved through his education-based coursework at a large, public university in the US Southeast. In his final year of college, Johnny chose to forego the remainder of student teaching and not to receive a teaching certificate. To better understand Johnny's choice to leave teaching, as well as the tension between Johnny's developing conceptions of care and teaching and those of his Mentor Teacher, I draw on sociocultural approaches to teacher identity development and literature on care in teaching. Findings from this study could inform the ways that school-based experiences preceding and during teacher education are structured to encourage PSTs to develop identities as caring teachers and to become members of communities of practice.
