ETC membership is open to all IASC members and, upon the invitation of the existing membership, to other organizations (i.e. United Nations, NGOs, governmental organizations, corporate social responsibilities organizations, private sector partners) that can make a positive contribution to the functioning of the ETC.

To be an ETC member the organization must have an interest in humanitarian assistance; support the achievement of the mandate of the ETC; and commit to making a positive contribution to the ETC by actively participating in or contributing to ETC activities at the global and local level.

To become a new member an organization will normally submit a request to the ETC Secretariat (Global.ETC@wfp.org) that outlines the nature of its interest; the role that it wishes to play; and a description of the contribution that it commits to make to the work of the ETC. Due diligence of the organization will be conducted to ensure its membership would not be inconsistent with humanitarian or IASC principles. Such requests will be reviewed by the full ETC membership, and a consensus reached to accept or reject the request.
