At the end of most training courses, students are typically required to take a certification test in order to demonstrate their knowledge and proficiency in the subject matter. The lifeguard training course is no different. Students who successfully pass the certification test will be awarded a certificate of completion, which will allow them to work as a lifeguard at most pools and beaches. The test consists of both a written and practical component. For the written portion, students will need to correctly answer questions about first aid, CPR, and water safety. The practical portion of the test will require students to demonstrate their ability to perform various rescue techniques. While the certification test can be challenging, it is a necessary step in becoming a lifeguard.
