Section 5: Rules of Play
NCAA Championship Events (SCY — Short-Course Yards)
- Freestyle: 50, 100, 200, 500, 1000, 1650 yd
- Backstroke: 100, 200 yd
- Breaststroke: 100, 200 yd
- Butterfly: 100, 200 yd
- Individual Medley (IM): 200, 400 yd
- Relays: 200 medley relay, 400 medley relay, 200 freestyle relay, 400 freestyle relay, 800 freestyle relay
Starts
- "Take your marks" — swimmers assume starting position; one whistle blast, then starting signal
- Backstroke starts: in the water, hands gripping the starting handles, feet braced against the wall
- Relay exchange: outgoing swimmer's feet must remain on the block until the incoming swimmer touches the wall (false start = relay disqualified)
Stroke Mechanics
Each stroke (freestyle, backstroke, breaststroke, butterfly, IM) has detailed technical rules per the World Aquatics rule book — kick patterns, body position, turn requirements, finish criteria. Stroke-and-turn judges enforce these on each lane. NCAA modifications include: NCAA-specific underwater dolphin-kick distance limit (15 m before breaking the surface for free, back, fly), specific freestyle relay take-off rule.
Turns
Each stroke has a specific turn rule (touch-and-go for breaststroke and fly; flip turn for free and back; specific transition turns for IM). Improper turn execution = disqualification.
Qualifying Standards
NCAA Championship qualifying is by published "A" (auto-qualifying) and "B" (consideration) cuts, with the field cap filled by descending-order list invitations. Cuts are published annually by the NCAA Swimming and Diving Committee.
