Here are the requirements for swimming that is defined in NAUI's course requirements,
"Demonstrate novice level swim stroke proficiency in any of the
following strokes: crawl, side, breast, elementary back or back stroke.
Classic stroke combinations are not necessary to meet this requirement
as long as forward progress is achieved, e.g. no particular kick or arm
action is necessarily required and a lack of either is also acceptable.
Students shall complete at least 15 continuous stoke cycles while being
evaluated by an instructor. A stroke cycle is considered to be either arm
or leg action or a combination thereof resulting in forward movement
