Course content
Session-by-session pathway
Six representative sessions show one learning cycle; coaches may repeat or adjust drills to actual progress.

How coaching and progress assessment work
Learn butterfly from scratch: body undulation, dolphin kick, and arm recovery coordination. Requires basic freestyle ability.

How coaches adapt the pathway
Butterfly Basics follows a progressive framework, but sequence, repetitions and challenge are adjusted after the coach observes readiness, movement quality and safety behaviour.
- Readiness is confirmed before difficulty, distance or depth increases.
- Feedback prioritises repeatable technique and safe decision-making over a single performance number.
- The next task is selected from observed capability, not from attendance alone.
Conquer the hardest stroke — from dolphin kick to full butterfly.
How progress is assessed
- Coach observation during preparation and technical practice.
- Application with the required supervision, communication and recovery procedure.
- A progress note identifying what is stable, what needs work and the recommended next step.
