The Academy Secretariat, which is based in Amman, is the IAS's executive arm responsible for maintaining its institutional set-up and implementing its plan of action within the guidelines set by the Council and General Assembly.

The Hashemite Kingdom of Jordan hosts the Academy Secretariat that had commenced fully its activities in April 1987.

Jordan, as well as offering the IAS an annual maintenance grant, accorded it the diplomatic immunities and privileges normally given to non-governmental organisations based in Jordan.

In 1987 also, HRH Prince Al-Hassan of Jordan, Patron of the Academy, graciously instructed the allocation of a plot of land to the Academy- near the Royal Scientific Society complex in Amman- for the building of its permanent headquarters.
