What I expect and fear next year: Measuring new teachers' possible selves

Possible selves theory describes the relation between self-concept and regulation of future-oriented behaviours. This theory helps conceptualise issues related to teacher development, including preparation and retention, but few researchers have done so. The validation of a Likert-type instrument intended to measure 'new teacher possible selves' is described. Student teachers in the United States (n = 335) completed the new measure in their final practicum semester. Results from two confirmatory factor analyses indicate that data fit well the models of new teacher expected and feared possible selves. Limitations and future research directions are discussed.
