It was established in 1985 under the Education Ministry of Iran.
Boys in the international school are expected to wear light blue collared shirts and dark blue trousers as part of their school uniform, while boys in the re-adaptive school are expected to wear blue collared shirts and dark blue trousers. Girls are expected to wear manto with maghnaeh.
