After careful consideration of Greek syntax and semantics, Pi Kappa Sigma was chosen as the name.

Pi Kappa Sigma planted chapters at different campuses throughout the United States.

Pi Kappa Sigma's status as a "pedagogical sorority" prevented it from being admitted into the National Panhellenic Conference.

[2] In November 1947, the National Panhellenic Conference (NPC) invited Pi Kappa Sigma and her A.E.S.

Under the rules of the NPC, Pi Kap had to withdraw such chapters from the roll until those institutions could attain the proper accreditation.

The history book (1949) included total membership records after the NPC affiliation.

Pi Kappa Sigma remained an NPC-affiliated sorority for only ten more years.

[4][3] Total membership reported in the 1957 Baird's Manual was 11,013, two years before the merger with Sigma Kappa.

The younger Pi Kaps wanted more definite shield patterns and "something symbolic of secrecy".

The sisters claimed that since other sororities had pins symbolizing secrets, so should the Pi Kappa Sigmas.

[2]: 419 The second badge was a "modified triangular shield with a narrow gold bevel surrounding a field of black enamel.

"[2]: 420 The pledge pin was a modified triangle in turquoise-blue enamel with the Greek letters ΠΚΣ in gold.

[2]: 420 The coat-of-arms was authorized by the Grand Chapter in 1927 and is described as a "quartered shield [gold and blue] shaped like the pin.

Beneath the shield are two crossed laurel branches; below them is a scroll with Pi Kappa Sigma in Greek letters.

We pray to fix in all our hearts the bright resolves to live nobly, truly, simply, and in the real spirit of Pi Kappa Sigma.

Help us to seize and improve every opportunity for the cultivation of our minds, the foundation of habits the preparation for future usefulness and gaining good.
