[5] Chi Omega was founded April 5, 1895, at the University of Arkansas by Ina May Boles, Jean Vincenheller, Jobelle Holcombe, and Alice Simonds, with the help of Dr. Charles Richardson, an initiate of Kappa Sigma fraternity.

[7] By its 10th anniversary, in 1905, and with the support of Alumnae and Dr. Richardson, Chi Omega had installed 17 chapters throughout the United States.

[11] As such, Chi Omega is the largest women's sorority organization in the world with over 355,000 initiates and 181 collegiate chapters.

Dr. Charles Richardson designed the first badge, and made it completely out of scraps of hammered dental gold.

[14] The ethos of the fraternity is embodied in a document known as the Chi Omega Symphony, composed in 1904 by Ethel Switzer Howard of the Xi Chapter at Northwestern University.

[16] Each chapter of Chi Omega receives at least an annual visit from a National Consultant who aids in the development of the members.

The sessions include a variety of topics based on personal development, and the program is available at various meetings and events.

[19] In 1971, the Delta Nu chapter at Dickinson College in Carlisle, Pennsylvania attempted to recruit an African-American woman as a member, and the national organization refused permission.

[20] In 2013, the chapter at Pennsylvania State University was shut down after the sorority threw an offensive party insulting Mexican-American culture.

National leadership of the sorority released a statement saying the party was not congruent with Chi Omega's values and purpose.

[22][23] An anonymous Chi Omega member told the school newspaper, The Crimson White, that their university-employed rush adviser dropped a black girl who received perfect scores after the first round of recruitment.

[27] The university's president and sorority's leadership both released statements condemning the photo and acknowledging the importance of embracing diversity.

The incident made it to a Good Morning America segment where she states she was unfairly treated and targeted by members of the sorority.
