There is research paucity concerning EFL learners’ self-formation, taking the role of IELTS writing skills into account. With a view to this, the present study aimed to see what a model of possible self-construction before and after training on IELTS writing skills emerges and what the psychometric properties of the emerged model are. To this end, a grounded theory approach was used. Of the IELTS candidates taking part in five IELTS preparation centers in Kerman, 90 (55 males and 35 females) candidates were selected as the participants of the present study through cluster sampling. A semi-structured interview was used to identify the possible selfof the participants. Coding procedures (i.e., open, axial, and selective coding) and Structural Equation Modeling (SEM) were used to analyze the data. According to the results, a model of possible selfconstruction before and after training on IELTS writing skills emerged wherein before training on IELTS writing skills, feared possible selfwere more dominant than expected and responsible possible selves. Furthermore, after training on IELTS writing skills, expected and responsible possible selfwere constructed more dominantly than feared possible selves. Implications of the results for EFL curriculum planners, teachers, and learners have been discussed.
