If an observer were to evaluate the effectiveness of women's organisations in Guam by their number, goal and scope, and wide-ranging membership, the impression created by approximately 75 women's organisations in Guam, representing the diverse ethnic, professional, religious, philanthropic, cultural and military segments of the island community, would be misleading. There are three federations or umbrella women's organisations with which 98 per cent of all women's organisations are affiliated. The 75 women's organisations are affiliated to one of the three umbrella organisations or federations.

The Guam Council of Women's Clubs was formed in 1982, by the First Lady of Guam at the time, to promote friendship and fellowship among the women in Guam. The two other federations boast a predominantly Chamorro membership. The Confraternity of Christian Mothers is comprised of chapters of each of the 19 Catholic parishes in Guam. Guam is divided into 19 villages; each village with a parish and in each parish has a Christian Mothers' Association which is affiliated to the Confraternity. Established at the turn of this century, its objective is to encourage the development of “Christian home education, children and truly Christian mothers”. The women of Guam, if they join any organisation, will usually start with membership in the Christian Mothers Association in their Parish. Those who are active organisers in the community have frequently attributed their personal growth and development as organisers, to their membership in the Confraternity of Christian Mothers.
