Iowa Girls High School Athletic Union

The Iowa Girls High School Athletic Union (IGHSAU) is the governing body for girls' junior and senior high school sports in the U.S. state of Iowa. The association promotes and regulates interscholastic sports among its member schools. Though its counterpart for boys sports in Iowa, the Iowa High School Athletic Association, is a full-time member of the National Federation of State High School Associations, the IGHSAU is only an affiliate member. It is headquartered at 5000 Westown Parkway, Suite 150,West Des Moines, Iowa 50266.

Sports currently overseen by the IGHSAU are basketball, bowling, cross country, golf, soccer, softball, swimming & diving, track and field, tennis, volleyball, and wrestling.

Sports previously overseen by the IGHSAU were gymnastics, synchronized swimming, and indoor track and field.

Administrative staff
Representation of the IGHSAU consists of an eight-person Board of Directors. Six positions are elected to the IGHSAU Board while two appointees representing the Iowa Association of School Boards and the Iowa Department of Education also serve. The Board of Directors approve policy changes proposed by the IGHSAU administrative staff.

The IGHSAU Representative Council meets twice a year.

IGHSAU Sport Advisory Committees
Each IGHSAU sport has an advisory committee made up of coaches, an official and an athletic director. These committees meet once a year to review their respective sports and develop recommendations for the IGHSAU administrative team to take to the IGHSAU Board of Directors.

IGHSAU Student Athlete Advisory Committee
The IGHSAU Student Athlete Advisory Committee is composed of female student-athletes from each of the state's four districts (NE, SE, NW, SW) along with three at-large representatives. Eleven girls were selected to two-year terms to meet about issues related to girls high school activities in Iowa. Committee members act as a voice for Iowa's female student-athletes and serve as a sounding board for the IGHSAU's Representative Council and the Board of Directors.
