NATO CCD COE membership is open to all NATO nations. In addition, the Centre can establish cooperative relations with non-NATO nations, universities, research institutions, and businesses as contributing participants. All formal contacts require the approval of the Steering Committee, which consists of representatives from the Sponsoring Nations.
NATO nations can become a Sponsoring Nation by signing the Memorandum of Understanding, which details all personnel and funding requirements.
Contributing participants are allowed to work with the Centre on specific projects. These are handled on a case-by-case basis and approval is granted by the Steering Committee. A contributing participant does not have a seat on the Steering Committee and is therefore unable to vote on the Centre's matters such as its budget and Program of Work.
