Assessing the activities and effects of a political system after a broad and fundamental revolution, despite the long periods of war and the crises caused by long-term sanctions etc, is clearly not an easy task. After passing four decades from the establishment of the Islamic Republic of Iran, it is now the time for scholars, performing reasonable scientific and statistic researches, to assess educational and scientific achievements of Islamic Revolution fairly in order to make the most important aspects of the system`s efficiency clear. Therefore, the present research is an answer to the following question: how may the educational and scientific achievements of forty years of the Islamic Revolution in the regional and international levels be assessd located and have they been able to show their effectiveness? May the achievements show the system`s efficiency? The research findings show that the origional and international achievements of the Islamic Revolution have dramatically increased to such a degree that Iran has been known as one of the world's scientific centers. The method of the study is analytical, descriptive, statistical and library-based.
