Professional identity development is a slow and complex process of self negotiation and re-negotiation. While the latter parts of this process tend to be stable, the initial parts seem to be more fluctuating and less predictable. This understanding urges a qualitative study to explore how EFL teachers shifts their profession identity from the early-career stage to mid-career stage. Factors contributing to their identification changes are also scrutinized. The study draws on an adapted theoretical framework which includes five sub-components of professional identity, namely roles and values, job motivation, satisfaction, commitment, and self-efficacy to examine the changes. An analytical framework with six influential stages of identification development is also provided to capture such adjustments.
