Beginning teachers (preservice and novice) must develop a resilient professional identity, yet high early attrition rates indicate the need for additional support in this process. Many attrition studies focus on external factors; few address teacher identity. According to developmental psychologists, identity commitments are concretized in a stepwise process, first by tentatively making them, and then by evaluating them. Most preservice and novice teachers are in a transitional stage, as they explore whether tentative commitments fit their sense of self. Our research tests the proposition that such exploration is often focused on determining whether a teaching career will satisfy their identity motives. We interviewed and collected self-reported written stories from 154 interns and novice teachers. Participants discussed their career choice in an initial interview and in a questionnaire focusing on recent, identity-relevant significant events administered at three points in time over a year. These career choice and written, field-based significant event stories underwent content analysis for the presence of identity motives, guided by a codebook developed for this research. This paper describes two central and innovative findings. First, identity motives are, indeed, present and highly salient in teachers’ career deliberations. Secondly, we found that beginning teachers express motives differentially, vary in the salience they accord the motives, and explore motives differently according to situational context. This differentiation in focus may indicate important shifting priorities and challenges as participants navigate the transition to the field. Taken together, these findings suggest that understanding and addressing identity motives in teacher development may enable more personalized and responsive tools that support teacher retention.
