Objective: The aim of the present study was to introduce and validate a tool for measuring students' individual agency. Method: The research was descriptive-correlational. The statistical population included 1364 student-teachers at Farhangian University, Kurdistan Province. A sample of 271 students was selected using systematic random sampling. Data was collected using the Individual Resources subscale of the Student Agency Scale (Jääskelä et al., 2017). The subscale has 28 items spread across four dimensions: participation activity, interest and motivation, self-efficacy, and competence beliefs. The questionnaire was translated into Persian, and semantic consistency with the original version was confirmed using the back-translation method. Subsequently, the face validity of tool was verified based on expert evaluations. Data analysis involved first- and second-order confirmatory factor analysis, convergent validity, Cronbach's alpha, composite reliability, and a one-sample t-test. Data analysis software included SPSS19 and Amos23. Results: The first-order factor analysis results indicated that the questionnaire items (after removing three items) could appropriately describe the latent variables. The second-order factor analysis results also revealed that the questionnaire items could be reduced to four components: activity engagement, interest and motivation, self-efficacy, and competence beliefs (RMSEA: .047; CFI: .93). The average variance extracted was 0.55, confirming convergent validity. The overall Cronbach's alpha was 0.87, and the Cronbach's alpha coefficients for the subscales ranged from 0.64 to 0.82. The composite reliability was 0.82. Results also indicated a high level of individual agency among student-teachers at Farhangian University (p < .05).
