This study has employed a qualitative approach, determined the components of Islamic-Iranian architecture and the consistency of the content of architecture with that components through the simulation research method. The findings show that in the current program of architectural education, the share of training the Islamic principles, personal and social values and contexts is very low compared to the share of training the architecture tools. On the other hand, architectural education has mostly emphasized teaching the architectural tools rather than the fundamentals, which prevents the architecture students to form a holistic insight into the issue.
