Who We Are

The World’s Largest Swimming Lesson™, created by the World Waterpark Association in 2010, is a global public relations event supported by aquatic facilities, waterparks, pools, swim schools, YMCA's, among others. The WLSL event serves as a platform to help the global aquatics industry work together to build awareness about the fundamental importance of teaching children to swim to prevent drowning. Swimming is a life-saving skill for children and a vital tool to prevent drowning, the second leading cause of unintended, injury-related death for U.S. children ages 1-14. Research shows risk of drowning can be reduced by 88 percent if children participate in formal swimming lessons between the ages of 1-4. Yet, a survey conducted by the American Red Cross in 2014 found that more than half of Americans (54 percent) either can't swim or don't have all of the basic swimming skills. This CAN and SHOULD change and this is the mission of TEAM WLSL™.

The 2021 World's Largest Swimming Lesson™ will be held on Thursday, June 17th. Host locations may select their own start time on the 17th to best suit their operating schedule. TEAM WLSL™ has sent the message Swimming Lesson Save Lives™ to billions of kids and adults. Let’s share this important message with as many kids and adults as we can throughout the summer of 2021.

Team WLSL Accomplishments

Since its inception, more than 320,000 children and adults have participated in WLSL lessons generating more than TWO BILLION life saving, learn-to-swim media impressions. The overall success of the WLSL event is thanks to the support it has received from thousands upon thousands of people who have hosted a lesson in their facility or come out to their local pool, swim school or waterpark to participate in a live event each year.

The problem is real

Per the Center for Disease Control, drowning remains the leading cause of unintended, injury-related death for U.S. children ages 1-4, and the second leading cause for children under 14; drowning is an even greater threat in other countries around the world.

Many lack basic swimming skills

In 2014, a survey completed by the American Red Cross found that more than half of all Americans (54 percent) either can't swim or don't have all of the basic swimming skills.

Parental supervision is key

According to a SafeKids Worldwide 2016 report, despite the fact that lack of supervision plays a role in the majority of drowning deaths, less than half of parents (49 percent) indicate they remain within arms' reach of their child in the water.

Swimming Lessons Make a Difference

Participation in formal swimming lessons can reduce the risk of drowning among children age 1-4 by up to 88%. According to a recent poll conducted by the National Recreation and Park Association (NRPA), more than 9 in 10 Americans (95 percent) believe it is important for children to learn how to swim at an early age.

Males & Minorities are at the Most Risk

Nearly 80% of people who die from drowning are male and the fatal drowning rate of African American children ages 4 to 14 is almost 3 times that of white children in the same age group.
