Following are the different types of water safety supervision in pool areas: Full Contact Supervision: Involves infants and kids who have no swimming skills. The supervisor needs to maintain full contact with the person in the water. Arms Reach Supervision: Involves kids with some swimming skills. Swim instructors often use this supervision at initial levels when teaching how to swim. Direct Deck Supervision: Involves kids of all ages with high swimming skills (those who passed a swim test). This supervision is done at deck level, at the pool's edge. Group (Lifeguard / Party) Level Supervision: A lifeguard or adult performs this type of supervision at a party, keeping an eye on multiple people or children in the water. Partner / Buddy Supervision: This type of supervision is done by a friend or buddy in the water. For example - lap swimming, surfing, scuba, swimming, hot tub use.
