COST is an intergovernmental framework consisting of 41 Full Members, 1 Cooperating Member and 1 Partner Member. The 41 COST Full Member countries govern COST via their representatives in the COST Committee of Senior Officials (CSO) ā the General Assembly of the COST Association.
This allows researchers from these countries to embark upon networking opportunities by participating in science and technology networks calledĀ COST Actions.
