Advance Preschool Learn to Swim: The objective of this class is to build on skills learned in Preschool Aquatics by providing additional guided practice of basic aquatic skills at slightly more proficient levels and greater distances and times.  Skills in this level are preformed independently.  Children improve coordination of combined arm and leg actions.  Students must have taken the preschool class to enroll.  Exit skills assessment:  Step from side into chest-deep water, move into a front float for 5 seconds, roll to back, float for 5 seconds then return to a vertical position.  Move into a back float for 5 seconds, roll to front then recover to a vertical position.  Push off and swim using combined arm and leg actions on front for 5 body lengths, roll to back, float for 15 seconds, roll to front then continue swimming for 5 body lengths.  Class ratio is 1:6.
