ACWW’s Board of Trustees is elected by the membership every three years at the Triennial World Conference. The World President, and the rest of the Executive Committee (the Chairmen of the Six Specified Committees: Agriculture, Communications & Marketing, Finance & Membership, Projects, Triennial Conference, and United Nations) are elected by the whole membership, whilst the 9 Area Presidents are elected by their respective areas. Three of the Specified Committee Chairmen also serve as Officers, and they are Deputy President, Treasurer, and Secretary.

The Board meets in full once per year, normally at Central Office in London. The Executive and Finance & Membership Committees meet three times annually, and the other committees meet between 2 and 3 times per year. As the costs of travel rise, some Committee members now join their meetings via online conference call or video.

ACWW's Central Office staff is a small group of professional administrators based in south-east London. With specific expertise in their given fields, the staff work to support the Board, and connect them with the Membership.
