This study was conducted in the academic year 2025 with the aim of validating the Persian version of the Career Decision-Making Profile questionnaire (CDMP) among 6159 students at Shahrekord University. The sample consisted of 447 students (213 male and 234 female) selected using Sample-to-item ratio of 10:1 (Kline, 2016), and convenience sampling. Data collection instruments included the Career Decision-Making Profile questionnaire and the Career Decision-Making Difficulties Questionnaire. Data were analyzed using SPSS version 27 and AMOS version 24. The results of confirmatory factor analysis indicated that the initial model of the questionnaire (36 items and 11 factors) did not have an acceptable fit. Therefore, after removing five items with weak factor loadings, the final structure consisting of 28 items and 11 factors achieved a desirable fit. The reliability of the test was also obtained at a desirable level through Cronbach’s alpha coefficients, test-retest, McDonald’s omega, Guttman, and composite reliability for the entire instrument and all factors (ranging from 0.73 to 0.98). Divergent validity was confirmed through a negative correlation with the Career Decision-Making Difficulties Questionnaire. In addition, all items had appropriate discrimination and difficulty coefficients, and normative tables were developed for the statistical population. Finally, it can be stated that the Persian version of the Career Decision-Making Profile questionnaire possesses appropriate factor structure, validity, reliability, and discrimination coefficients and can be used as a valid tool in career guidance and counseling as well as related research in Iran.
