The qualitative population comprised 8 psychology professors selected via snowball sampling to assess content validity using the Waltz and Bausell method. The quantitative population consisted of teachers in Bandar Abbas County; 500 were selected via multi-stage cluster sampling, with final analyses conducted on 494 individuals. Data were collected using the back-translated Teacher Empowering Structure Scale (Altinkurt & Iliman, 2017). Item analysis was conducted using Classical Test Theory (CTT) and the Graded Response Model (GRM).<br> <b>Results:</b> Content validity indices indicated satisfactory Content Validity Ratio (CVR = 0.972) and Content Validity Index (CVI) values. Confirmatory Factor Analysis supported a five-factor structure: Participative Decision-Making Environment (9 items), Responsive Environment (4 items), Professional Development Supportive Environment (4 items), Facilitating Environment (7 items), and Autonomy Supportive Environment (6 items). Item factor loadings ranged from +0.41 to +0.93. Based on the GRM, the items exhibited optimal information around the average theta level. Internal consistency analysis showed an overall Cronbach&rsquo;s alpha of 0.876, while IRT marginal reliability coefficients for the subscales ranged from 0.77 to 0.90.<br> <b>Conclusions:</b> The findings indicate that the Teacher Empowering Structure Scale demonstrates strong validity, reliability, and measurement precision, making it a suitable and robust tool for assessing the empowering structure among teachers in the Iranian population.</span></span></span></span></div> Psychometric properties, Teacher Empowering Structure, Classical Test Theory (CTT), Graded Response Model (GRM) 0 0 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-1102-1&slc_lang=en&sid=1 Masomeh Bahamin masomeh.bahamin@iau.ir 0000-0000-0000-0000 No Department of Psychology, BA.
