The Xi Theta Chapter, established by the California State University, Dominguez Hills, School of Nursing now has over 300 members. An eleven-member steering committee made up of students, faculty, alumni, and community members designed a structure that encourages participation of members throughout California. The Society became a Chapter of Sigma Theta Tau International Honor Society of Nursing in April 1994. 2004 marked the 10 year anniversity for Xi Theta.
The Nursing Student Organization (Nursing Student Organization) was established to serve as a conduit between students, the faculty and the staff of the CSUDH Division of Nursing. The board members consist of one student representative for each region (BSN and MSN) of the Division of Nursing. The Nursing Student Organization Board meets by telephone conference three times annually to develop activities and programs for the benefit of students.
