What does the YMCA’s Swim Test consist of?

For safety reasons, we ask that any swimmers who are 13 years old or younger pass a brief swim test. The test consists of:

  • Deep water plunge with head going below the surface of the water
  • Surface and swim 25 yards without resting or stopping
  • 30-second tread or float

A test won't be required if the child or teen will be within arm’s reach of someone 14 years old or older for the entirety of the time they are in the water.

Can I sit on the pool deck while my children swim?

If your children pass our swim test, you do not need to be in the water with them and can sit on the pool deck while they swim. We ask that you stay on the pool deck during your reservation while your children are in the water. Everyone entering the facility, whether using the pool or not, is required to have a reservation.

If I have a child that doesn’t want to swim, can they sit on the pool deck?

We will have designated seating for each family that enjoys open swim. If members are not in the pool, they should be seated in their designated area and continue to abide by pool rules or appropriately supervised by an adult.
