Design/methodology/approach This study adopted a descriptive methodology by using a survey method. The statistical population consisted of 8,548 faculty members of comprehensive universities all over Iran. Considering the large size of the population, the comprehensive universities were categorized into five clusters (North, South, East, West and Center). The authors selected the faculty members from different clusters using Cochran’s formula. A total of 367 faculty members were selected from five clusters. For data gathering, a researcher-designed questionnaire was used. In data analysis, statistical procedures including the Confirmatory Factor Analysis, Kolmogrov-Smirnov test, one-sample t-test, and Friedman test were performed. Findings The findings of the research showed that except for academic freedom, other components of world-class university in Iran’s comprehensive universities were lower than the mean.

Therefore to reach a desired level in comprehensive universities’ preparation for converting to a world-class university, it is essential that the policy makers and organizers of Iran’s higher education system pay greater attention to items such as research motivation, research innovation, research budget increase, authority reduction on various university departments, internet bandwidth increase and laboratory facilities increase.
