These skills can be successfully taught in both shallow and deep water. The key to successful submersion is that the student is relaxed, comfortable in the water and able to control their breathing.
A student has achieved submersion once they are able to perform all skills confidently.
If the student has mastered some but not all the skills, they should be assessed as not yet achieved.
Example skills were filmed in a 1m deep pool.

A student can build and extend on these skills even after they have been achieved. For example, a student could be asked to pick up an object in deeper water or, for the very advanced, retrieve a lifesaving practice dummy.
