The present research probed the sociocultural challenging variables which may affect EFL learners’ identity formation during their language studies in an Iranian context. A thorough analysis of the literature encompassing EFL teachers’ opinions and EFL coursebook analyses was performed to develop a comprehensive view of the recognized sociocultural domains and variables. Furthermore, an open-ended questionnaire was designed and distributed among 50 adolescent male and female EFL learners at the age range of 13-21 years (M=16) as Erickson’s identity confusion stage to identify the newest sociocultural challenging variables in the present Iranian context. The result of the research led to compilation of a Sociocultural Variables Inventory presenting an extended range of variables operating in the context of Iranian EFL learners’ identity formation. The inventory could act as a basis for research in the fields of TEFL, sociolinguistics, cultural studies, and further interdisciplinary research.
