The purpose of this research is examining the validity of the Islamic banking evaluation model in Iran in line with the macro program of the system for reforming the country's banking system. This study is applied in terms of objective and descriptive-survey in terms of method. The statistical population consists of 160 managers, deputies, and heads from 12 public and private banks in the country who were familiar with Islamic banking. Using Cochran's formula and simple random sampling based on the population size, the sample size was determined to be 113 individuals; however, to account for a 10% non-response rate, 127 questionnaires were distributed, and ultimately 122 questionnaires were returned. Data were collected using a questionnaire, with validity assessed through face validity, content validity (using Lawshe's CVR), and reliability evaluated via Cronbach's alpha (0.814). In this research, second-order construct modeling of the reflective-reflective type was employed using the partial least squares (PLS-SEM) method in SMART PLS software. The findings of this study indicate the validity and adequacy of the Islamic banking evaluation model in Iran. All 13 examined indicators are significantly associated with the model core, demonstrating a strong relationship between these indicators and the model. The indicators of "establishment of Sharia supervision and compliance mechanisms" (β=0.845, T=7.807) and "trusteeship management" (β=0.789, T=7.330) have the strongest effects, while "support for welfare and sustainable economic development" (β=0.569, T=3.552) has the weakest effect but remains significant. Model fit indices (SRMR=0.05, NFI=0.92, GOF=0.773) indicate a very good fit of the model with the data. Additionally, the model's reliability was confirmed with Cronbach's alpha (0.776-0.854) and AVE (0.769-0.810), reflecting high predictive power and strong internal validity. Based on the analysis of data collected from bank managers, the findings of this research confirm the structural adequacy and significant association of the proposed indicators with the overall concept of Islamic banking evaluation. This model, by encompassing Sharia, ethical, social, and operational dimensions, provides a coherent framework for assessing the performance of Islamic banks in Iran and can serve as a foundation for subsequent empirical studies and the development of indigenous evaluation tools.
