The Iran Language Institute, previously referred to as Iran America Society, was established in 1304 in Tehran. In the past, Iran America Society provided various educational services including teaching English to business people and employees in both public and private sectors, and also teaching Persian to foreigners.

After the Islamic Revolution, this society affiliated with the Institute for the Intellectual Development of Children and Young Adults and, therefore, expanded its services.

The ILI, currently having around 200 centers in 73 cities, teaches English, French, German, Arabic, and Spanish to around 240000 learners. Mr. Hassan Masoudi is at present the Director of the Iran Language Institute.
