Swimmers must be able to confidently swim front crawl and back crawl unaided for at least 5 metres to join a Beginner class. Depending on the venue layout, swimmers may not be able to stand in the lesson tank. During lessons swimmers will be building on technique for front crawl and back crawl and will be introduced to breaststroke and butterfly. Aids will be used to help improve technique along with unaided swims. The maximum number of swimmers per Beginner class is five.
