Lambda Pi Eta was initiated by the students of the Department of Communication at the University of Arkansas at Fayetteville, and was then endorsed by the faculty and founder, Dr. Stephen A. Smith, in 1985. Lambda Pi Eta became a national society in 1987, affiliated with the National Communication Association in 1988, and became the official National Communication Honor Society of the National Communication Association in 1995. Emporia State University's Xi Sigma Chapter was approved on May 17, 2002, by the national office and received ESU organizational recognition on October 10, 2002.
