The American Red Cross lifeguard training course is a comprehensive program that teaches participants the skills they need to safely staff a pool or beach. The course includes instruction in first aid, CPR, and AED use, as well as water rescue techniques. In order to take the course, participants must be at least 15 years old and able to swim 300 yards continuously, perform a deep-water dive, and tread water for two minutes. After successfully completing the course, participants will be certified as lifeguards for two years. The American Red Cross also offers recertification courses for lifeguards who need to renew their certification.
