Iran has a network of private, public, and state-affiliated universities offering degrees in higher education. State-run universities of Iran are under the direct supervision of Iran's Ministry of Science, Research and Technology (for non-medical universities) and Ministry of Health and Medical Education (for medical schools). According to article 3 of the Constitution of the Islamic Republic of Iran, Iran guarantees "free education and physical training for everyone at all levels, and the facilitation and expansion of higher education." IANI representatives say that academics in Iran are "ultimately directed by the regime and military when it comes to specific areas of research". Rana Dadpour, who taught at an Iranian university, said that certain areas of research are directed by the Islamic Revolutionary Guard Corps and could be employed for "surveillance or military purposes".[2]
