This study aimed to validate the 70-item Grammar Learning Strategy Inventory (GLSI), originally developed in Poland, in the Iranian English as a foreign language (EFL) context. A heterogeneous sample of 605 Iranian EFL university students completed the GLSI. Results of exploratory and confirmatory factor analyses revealed a seven-factor model, allowing for the construction of a reduced version of the GLSI including 36 items. The underlying structure of grammar learning strategy (GLS) use corresponded to the classification that served as a basis for the GLSI. Thus, the division into metacognitive, social, affective, and cognitive GLS, the latter of which are further subdivided into focus-on-form GLS, explicit knowledge GLS, implicit knowledge GLS, and corrective feedback GLS, is conceptually valid in the Iranian context. However, the drastic reduction in the number of items might indicate that the actual nature of learning L2 grammar in the Iranian context might be different and that the GLSI may have failed to capture some GLS that Iranian students may draw upon. More research, preferably such that would combine quantitative and qualitative methodologies, seems indispensable for developing a research tool that can be more reflective of the specificity of GLS use in the context under investigation.
