Final answer:
A Red Cross Instructor can teach First Aid and CPR with a general certification. For Lifeguarding or Water Safety Instructor courses, additional specialized certifications are required.
Step-by-step explanation:
If you are certified as a Red Cross Instructor, you are qualified to teach courses in several areas, depending on the specific instructor certifications you have obtained. A general Red Cross Instructor certification allows you to teach First Aid and CPR. To teach Lifeguarding or become a Water Safety Instructor (WSI), you need to obtain additional, specialized instructor certifications.
For example, to teach Lifeguarding courses, an individual must become a Lifeguarding Instructor through the Red Cross, which requires taking a separate course that focuses on lifeguarding skills and instruction. Similarly, to teach swimming and water safety classes, one must earn a Water Safety Instructor certification. Each of these certifications focuses on the specific skills and knowledge required to teach those subjects effectively.
