By National Council in 1937, Kappa Phi had spread from West Virginia and Ohio to the Pacific coast and numbered over 17,500 members in 25 chapters. At this Council, the ritual for the Degree of the Rose was accepted, a Sponsor Handbook completed and the Alumnae Constitution adopted. By now the Alumnae work was outstanding, for the first Kappa Phis were now leaders in their communities.
By the 1939 Council, Kappa Phis everywhere were concerned with international problems and that year, a Kappa Phi, Ethelyn Whitney, went to the International Youth Conference at Amsterdam as the first Kappa Phi representative abroad.
During the period from 1953-1963, there were important changes in Kappa Phi, aimed at streamlining the organization to keep pace with present day campus life. The ritual was revised, a pledge plan of self-evaluation was instituted, the Club philosophy was stated, and the aim re-worded. During these years Alberta Meadowcroft, who has written so many Kappa Phi songs, compiled the History of Kappa Phi.
In 1966, Kappa Phi was 50 years old. This anniversary was celebrated at the 1965 National Council with the attendance of the Founder, Mrs.Gordon B. Thompson. Council was held at the University of Kansas, Lawrence, where Kappa Phi was born. It was truly a great occasion for Mrs. Thompson to be able to celebrate the 50th birthday of a dream come true and to give the banquet address. She died the following October.
Recognizing that many university women of Christian denominations other than Methodist were interested in Kappa Phi, and thinking that the club should be more ecumenical in membership, the wording of the membership provision was changed to include those "who find interest and meaning in this Christian group." This was a part of the 1965 Council.
In 1968, Kappa Phi embarked on a five-year development plan, entitled "Encounter." For the first time in its history, the club examined sites for new chapters. Other goals included strengthening local and alumnae chapters, and training of adult leadership. At the 1969 Council of Chapters, major revisions in the Constitution were made to aid in accomplishing these goals. In January 1970, the Encounter Committee met in Chicago, and after an intense planning session, it developed the concept of workshops for adult leadership to help in strengthening chapters. The enthusiasm of those participating in the workshops led to Enrichment Workshops for both adult leaders and chapter officers and the recommendation that a permanent Development Committee be established.
