The Wisconsin Interscholastic Athletic Association (WIAA) is the regulatory body for all high school sports in Wisconsin. Its history dates to 1895, making it the earliest continually existing high school athletic organization in the country. It also provides the licensing program for more than 10,000 officials in the state, and oversees junior high or middle school athletics in about 100 of the state's nearly 400 school districts. Among its duties are the administration of state tournament series in its various sports, overseeing eligibility and conference alignment, and promoting sportsmanship.
