The Illinois Swimming Officials Association (ISOA) is the only IHSA-recognized swimming and diving officials association and is committed to the profession of officiating high school swimming and diving in Illinois.

We are a group of IHSA-licensed independent contractors who officiate swimming and diving meets for IHSA-member school teams. The IHSA governs the learning and training requirements for officials. All IHSA schools must follow the same rules relative to eligibility and competition. As officials, we enforce the rules at the high school competitions.

The Illinois Swimming Officials Association provides a place for professionals to hone their craft of officiating. Our association offers professionalism, consistency, community, camaraderie, mentorship, and learning opportunities. We work with the Illinois Swimming and Diving Association (ISDA) to promote high school swimming and diving in Illinois.
