The swim study has shown that young children who participate in early-years swimming seem to be achieving particular milestones quicker than the normal population across physical, cognitive and linguistic domains. Many of these skills are highly valuable for the transition into other learning contexts; and will be of considerable benefit for young children as they enter preschools and school. It is widely recognised that the early years lay the foundations for learning. It would appear that early-years swimming may help develop skills beyond those of swimming, and which are of considerable value in formal education. It may be of national benefit for children who traditionally do not do well at school, particularly in the early years, to participate in learn-to-swim. This may help in the transition to school but also for the obvious benefits of water safety and general well being.
