I'm currently a Dive Master Candidate. I waited to enter the program after I felt
I was confident in my ability to help the students and competently assist the instructor. I had spent enough time with my LDS before enrolling that I knew the instructors prior to getting in the water with them and their students. The instructors I work with value my opinion and asked me for assistance in recognizing students who may need extra help. The instructors would expect me to bring things to their attention. After all they are working one on one with students. Our job is to observe all the other students during that time. I would recommend that your son realize that the instructor is relying on his observations during the classes.
