The current article investigates teacher identity construction at the tertiary level educational institutions of Pakistan. Identity is the sense or perception about oneself and the position or role one has in a given context and environment; teachers construct their identities in the specific work and Institutional environments they face every day. This research adopted the Life History approach to narrative inquiry, where five participants were selected through purposive sampling. The data were collected through a semi-structured interview protocol that focused on the narratives; the narratives were inductively analyzed vertically and horizontally to reconstruct identity portraits for each participant. The portraits also presented commonalities and convergent issues and themes in identity development, such as the effect of positive or negative educational experiences; the role of the organizational culture, leadership and colleagues in shaping identity; the difficulties, negotiations and challenges experienced in the construction of identity; time and workload management issues.
