When teaching participants, instructors must always train to the __ and test to the __.

In the context of teaching lifeguard skills, it is essential for instructors to train participants to the standard and test them to the objective. This approach ensures that the training meets the established criteria for safe and effective lifeguard practices, which are fundamental to ensuring safety in aquatic environments.

Training to the standard means that instructors focus on the established benchmarks of skill, knowledge, and behavior expected of lifeguards. Standards are typically set by authoritative organizations, such as the American Red Cross, and encompass everything from surveillance and rescue techniques to first aid and CPR skills. By training to these standards, instructors can be confident that their participants are learning what they need to effectively perform their duties as lifeguards.

Testing to the objective involves assessing the participants' understanding and proficiency based on specific goals outlined within the training program. Objectives provide measurable outcomes that help in evaluating whether the training has been effective and whether participants can perform the skills required as lifeguards. Testing ensures that lifeguards not only know how to perform skills but can demonstrate them reliably under scrutiny.

This method of training and testing upholds a high level of safety and professionalism in lifeguard instruction, which is critical in preparing capable and responsive lifeguards.
