Student satisfaction is one of the concerns of the higher education system in the country which has been less studied. This article is based on research that identifies and prioritizes the variables that affect students' satisfaction. Data were collected and analyzed using a researcher-made questionnaire with a sample size of 409 members of 11 faculties of Razi University.The study included two areas of students' expectations and their mental perceptions of university performance. Satisfaction with different variables that can be divided into macro, middle, and micro dimensions is affected. In this paper, some micro and middle variables are investigated. In summary, the findings of this study showed that there was a positive and significant relationship between the five variables studied (teacher-student interaction, university brand image, space and equipment, staff behavior, and sports cultural facilities) and student satisfaction level. However, what is noteworthy is the lower "service received" (affected by the current performance of universities) than the "student expectations" in all the indicators studied. Therefore, no matter what causes the expectation to decrease or increase the level of perceived performance, it can be said that the satisfaction level is lower than its required level, and this indicates a weakness in the university service management system. Another important finding of this study is the high level of “student-teacher interaction” on student satisfaction.
