Level 1 and Parent Tot.
 
Our primary focus is going underwater.
 
When you can go underwater then you can do everything.
 
The only thing you can do without going underwater is supported activities (being physically held up at surface) and backstroke.
 
One must learn how to go underwater. They should learn how to react when submerging, how to hold breath, blow bubbles, and not to panic when not able to breathe underwater.
 
We do that by repeatedly giving opportunities to go underwater to the participant. We build into almost every activity some chance to put the face in.
 
Examples:
 

Bobs
Rings
Superman through hula hoop
Supported Front glides
Kicking
Arm circles
Bake a Cake
Jumps
Monkey walks

 
Level 1 testable skills:

Go underwater completely on own
Supported front glide with face in water
