One of the main challenges of the current money market is the failure to identify, identify and disclose the credit risks of banks. Rating agencies require different rating patterns for a variety of institutions.

This research is mainly descriptive and comparative in terms of the purpose of the study as it attempts to define the credit ratings pattern of banks. The first step in presenting this model is to identify the dimensions and components and ranking indices that were asked after expert theoretical foundations in the form of questions and their opinions were evaluated using Delphi technique with the aim of reaching consensus .Finally, the final model obtained consists of 5 dimensions as follows: Independent credit rating with 6 components of asset quality, financing and liquidity status, profitability and capital status, competitive status, risk and management status, and 60 indicators, then other qualitative features with The 10 indicators are the institutional support rating with 4 indicators, the government support rating with 4 indicators and the country credit rating with two indicators.
