World Aquatics

A mechanical surface agitation system is mandatory at all World Aquatics-sanctioned competitions. This system produces a visible disturbance on the water surface (bubbles, spray jets, or drip jets) so divers can judge their height and distance from the water during flight.

Section 4: Players & Officials

Different

NCAA

NCAA Diving Championship qualification is via NCAA Zone Diving Meets — five regional Zone meets contested in the weeks before the NCAA Swimming and Diving Championships, with a specified number of qualifiers from each zone advancing per gender per event.

World Aquatics

Each diver competes alone, performing a prescribed number of dives from a published dive list. Preliminary rounds narrow the field to 18 (semifinal) and then 12 (final).

Section 5: Rules of Play

Different

NCAA

Each dive is judged on approach, takeoff, elevation/distance, execution, and entry. The diver must hit the announced dive position; failure to do so results in degraded scores or a "failed dive" (zero score) per the rule book.

World Aquatics

The DD is a numerical coefficient calculated from a formula published in the World Aquatics DR tables. It accounts for the dive group, number of somersaults, number of twists, body position, and starting position (running approach, standing, or armstand).

Section 6: Scoring

Different

NCAA

Sum the dive scores across all dives in the event (typically 11 dives for NCAA championship). Highest total wins the event.

World Aquatics

Each judge awards a score from 0 to 10 in half-point increments. The descriptive scale is: 0: Completely failed; 0.5–2.0: Unsatisfactory; 2.5–4.5: Deficient

Section 7: Violations & Penalties

Different

NCAA

Failed dive (zero): dive not performed as announced, dive position not held, dive landing not in standard entry, repeated incomplete dives. Rule 4-31, as clarified under the 2025-26 and 2026-27 Swimming and Diving Rules Changes, sets the specific instances in which a dive must be declared a faile...

World Aquatics

A dive is declared failed and scored 0 if the executed dive differs significantly from the announced dive — for example, performing the wrong number of somersaults, wrong group, or wrong position. The referee makes this determination.

Section 8: Safety Considerations

Different

NCAA

Diving is a high-impact sport with significant injury risk from board-strike, water-entry impact, and platform fall. NCAA-mandated minimum pool depth is critical (insufficient depth = forbidden dive).

World Aquatics

Mechanical agitation (bubbles or spray) is mandatory during all competition and practice sessions. The system must produce visible surface disturbance directly below all boards and platforms in use.
