If you have students on different skill levels you can let your swim instructor know. Your instructor will come to you on the first day of lessons with a game plan that approaches both skills levels. After the swim instructor has had a chance to assess the skill-sets of the students, they can give you a more in depth evaluation on the next steps they suggest moving forward. Our office is a great resource as well! Give us a call at 1-888-950-7946 to speak with our knowledgeable customer service representatives. They can help you choose the right options.
