Abstract Despite the important issue of high-reliability organizations, it has not been adequately addressed in our country. Scientific designs that can accurately assess organizations and various assessments and evaluations in the situations of organizations and the possibility of decision-making of organizations and improvement programs are decisive. This aims to provide a comprehensive research need for evaluating high-reliability blocks. In this research, the meta-synthesis method has been used, during which, based on the seventh-stage method of Sandelowski and Barroso, related sources and models have been examined and analyzed, and finally, a five-level model with a comprehensive view has been designed, in which at each level, the characteristics of determining the maturity level have been presented. This model can be used to evaluate and analyze the maturity level of high-reliability organizations, as well as to design an improvement and development program for these organizations.
