In 1923 the old "XX" was abolished and replaced with an Executive Committee of seven. This board, comprised of the "AA", "CC", "DD", "EE", and three members-at-large, was the governing body of the fraternity between conventions. A new "XX" was created as an advisory body to the Executive Committee; its membership consisted of the "BB"s elected by each chapter.

There were other internal improvements during the period between the World Wars. The position of Executive Secretary was created in 1923 and provision made for a permanent central office which was finally established in 1929. The position of Director of Scholarship came into being in 1925 to lead the drive for general scholastic excellence. In 1927, one full-time Field Secretary was placed in direct contact with the chapters and, in 1935 a second one was added to the staff. By 1930, Delta Chi had grown to 36 chapters and, in 1934, the Headquarters began publishing the Quarterly.

During this era Delta Chi made two noteworthy contributions to the Greek letter fraternity world. The first of these was the Tutorial Advisor Plan--members of the faculty (preferably not members of the Fraternity) living in the house where they acted as tutors, advisors, and counselors.

In yet another way Delta Chi took the lead among Greek letter organizations. At the 1929, Estes Park Convention, Delta Chi unanimously voted to abolish "Hell Week." (The following day another national organization, meet-ing in convention, also abolished hazing.)

The position of "EE" was also abolished at the 1929 convention and, at the 1935 convention, the Executive Board was increased to nine. Without realizing the full significance of what it was starting, the Pennsylvania State Chapter in 1937 invited six chapters in neighboring states to meet with them. Dean C. M. Thompson, who was then the "AA", saw the great potential of such gatherings and promptly asked the Indiana Chapter to be host for the first Midwest Regional Conference. After that the Regional Conference plan blossomed. But with World War II and the temporary suspension of many chapter operations, much about the mechanics of the Regional Conferences was forgotten. But the need, desire, and concept were not forgotten. After the war, Delta Chi saw its conference program expand and become more purposeful.

Today the Regional Conferences play an important role in the affairs of the fraternity. The conferences are the vehicle for the election of each Regent for a two-year term. More important, each conference is designed to accomplish specific purposes, including the development of new approaches to the solution of Fraternity problems; fostering a better understanding of the operation of the various programs of the general Fraternity and the Headquarters; promoting good will in university-fraternity relations; and bringing together large numbers of Delta Chis for information, inspiration, and plain good fun.

After the Great Depression and on the verge of the United States entering World War II, the Fraternity celebrated its 50th Anniversary with 35 chapters. Once again our young men went off to war and many of the chapter houses were taken over by the military as was done during the first world war. It was the alumni dues program, started in 1935, that provided the main source of revenue to the Fraternity while the chapters were not in operation.

The war ended and the chapters resumed normal operations. By 1950, Delta Chi had 39 chapters. 1951 saw the retirement of O.K. Patton from the position of Executive Secretary which, while he was a professor of Law at Iowa, he had held part-time since 1929 on an official basis. Prior to that time he had effectively operated the central office since his election as "CC".

Prior to 1929, the membership records of the fraternity would follow the election of the "CC" and the financiall records would follow the election of the "dd". When O. K. Patton was elected "CC" in 1923 he put the records in one room of a downtown Iowa City building and hired one part-time secretary. After the "general" membership question was resolved, Delta Chi grew from 21 to 36 chapters in four 1929 and the records and related activities had expanded to four rooms and four secretaries. Effectively after the fact, Delta Chi established its Headquarters in Iowa City where it has stayed.
