What is the correct Swim-Tread-Swim sequence for Lifeguarding?

• A. Jump in, submerge, resurface and swim 150 yards using the front crawl, breaststroke, or a combination; tread water for 2 minutes using only the legs; swim 50 yards using the front crawl or breaststroke.
• B. Tread water for 2 minutes first, then jump in and swim 150 yards, then swim 50 yards.
• C. Swim 50 yards first, then 150 yards, then tread.
• D. Jump in and swim 100 yards, then tread for 3 minutes, then swim 25 yards.

Answer: (A)

Swim-Tread-Swim is about showing endurance and the ability to switch from continuous propulsion to a buoyant, energy-conserving phase and back to propulsion. In the standard test, you enter the water and briefly submerge to simulate a victim search, resurface and swim a long distance (150 yards) using a front crawl, breaststroke, or a combination. Then you tread water for 2 minutes using only the legs to demonstrate staying afloat and conserving energy, followed by finishing with another swim (50 yards) to safety. This sequence specifically tests sustained swimming ability, proper treading technique, and transition between active swimming and treading under fatigue. Other options don’t fit the standard pattern: they either reorder the components (treading first, or finishing before the second swim) or use different distances or times (such as 3 minutes or 100/25 yards), which don’t match the required Swim-Tread-Swim sequence.
