The Officiating Swimming and Diving course was developed by the NFHS in conjunction with the National Interscholastic Swim Coaches Association (NISCA) and USA Diving. This course explores the elements of professional development and the fundamentals of officiating strokes and turns. The course also explores officiating and judging diving, and provides a judging practicum that includes feedback of submitted scores. Officials may select either the swimming tract, the diving tract, or both, depending on rules required by their state association.
