This chapter discusses the problem of teacher retention as it relates to handling the unexpected, whether it be meeting the needs of all learners, classroom management, or any other problem teachers may encounter. The authors propose that teacher education programs can support the growth of preservice teachers by helping them to develop teacher identity early in their learning through experiences and autonomy. In addition, preservice teachers should develop a growth mindset to promote agency when encountering learning obstacles and to engage in reflective practice. By identifying as teachers, allowing themselves to grow, and being proactive in searching for ways to improve their practice, preservice teachers can better prepare themselves for the reality of teaching and, hopefully, remain in the teaching profession.
