Swim Class Information and Registration Helpful Hints

Our swim lesson program is based on the American Red Cross Learn to Swim model. Lessons are taught by our enthusiastic, safety minded and caring staff and volunteers. All our instructors participate in on-going training and skills development.

Class information

  • Participants must be the proper age and skill level on the first day of class. If a student does not meet the minimum requirements for age or ability, every effort will be made to transfer the student to a class at his/her level. If space is not available a transfer to a later session or refund will be offered.
  • Children must be a minimum of 6 years old for Level 1-6
  • For the comfort and development of your child, adult lessons begin at age 13.
  • Please read the level descriptions carefully and select the appropriate level for your child based on his/her current skills.
  • It is not uncommon for a child to stay in a particular level several sessions before successful completion.
  • Please make sure to check the location of the class on your receipt to make sure you are signed up in the facility you have requested. 
  • Children not potty trained and in diapers must wear a swim diaper during class. Swim diapers may be purchased at the pool.
  • Appropriate swim attire is required.

In an attempt to keep our pools running efficiently no street clothes are allowed in the pool at any time.
