For years, in order to safeguard the ritualistic secrets of the Fraternity, Diggs laboriously typed and bound the rituals. It was not until he moved to Indianapolis, Indiana, where he met an old German printer in whom he had confidence, that he entrusted the esoteric materials of the Fraternity to a commercial printer.

In the spring of 1912 Diggs wrote in a little blue examination book the first Constitution, which was adopted in 1920 with but a few revisions. This edition remained in use until 1926 when it was supplanted by the codified edition jointly written by Diggs, J. Ernest Wilkins, and W. Ellis Stewart. In 1957 the Constitution again underwent major revision.

Now substantially established and provided with a Constitution, Ritual, coat of arms, motto, and guiding hand in a dynamic Grand Chapter, the Fraternity was ready for expansion. In the summer of 1912 Diggs visited the University of Illinois at Urbana, Illinois, where he met Earl B. Dickerson, President of the Old “Illini Club.” This club constituted the nucleus of the University of Illinois Chapter, the Beta, which was chartered on February 8, 1913. Gamma Chapter (later changed to Indianapolis Alumni Chapter) was established on December 29, 1913, followed by the establishment of Delta Chapter at the University of Iowa, on March 7, 1914. The latter was subsequently changed to Gamma Chapter, and the designation of Delta assigned to the Wilberforce University Chapter at Wilberforce, Ohio. Epsilon Chapter, Lincoln University, Pennsylvania, was established December 4, 1915, as the first chapter in the East. Elder W. Diggs journeyed from Indiana to give this chapter his personal and official installation, recognition and blessing.
Thus ended the infancy of KAPPA ALPHA PSI, whereupon the Fraternity embarked upon an era of expansion. Except for the years of World War I and II, when several Grand Chapter meetings were suspended, KAPPA ALPHA PSI has grown and prevailed with unabating impetus.

KAPPA ALPHA PSI Fraternity, relatively early, envisioned the modified attitudes of college administrators and administrations regarding certain frivolous activities previously identified with Greek letter organizations; and it initiated appropriate changes. Among the early changes brought about was the banning of paddling and other forms of physical abuse, and the introduction of constructive endeavors during pledge ship and probation. To date, KAPPA ALPHA PSI Fraternity is organizationally and administratively mature. It moves steadily toward a tomorrow of promise, productivity and influence.
