The teacher’s professional identity (TPI) defines their perception of how to behave in their teaching profession, and it may have a significant role in determining their place in educational advancement. Yet, the moderator influence of L2 Teacher Grit (L2TG) , Critical Thinking (CT), Teacher Resilience (TR), and Teacher Self-efficacy Beliefs (TS-EB) on TPI has not been extensively documented in the literature. To fill this lacuna, this study developed a model to show the interplay between TPI, L2TG , CT, TR, and TS-EB. The Teacher’s Professional Identity Scale (TPIS), the L2-teacher Grit Scale (L2TGS), the Watson–Glaser Critical Thinking Appraisal Form (WGCTAF), the Teacher Resilience Scale (TRS), and the Teacher Sense of Efficacy Scale (TS-ES) were given to 437 English as a foreign language (EFL) teachers for the intention of collecting this data. Following the findings of Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM), L2TG , CT, TR, and TS-EB can enhance TPI among EFL teachers. Finally, the implications and future direction were offered to enthusiastic educators and researchers which may enhance their awareness of the link between TPI, L2TG , CT, TR, and TS-EB and the way it can generate great results for the educational system.
