When candidates arrive for IDC training, I can usually predict the most common challenges I’ll see — not because the divers are lacking, but because these areas are rarely emphasized in recreational training.
Weaknesses I most often see:
-
Knowledge confidence — they underestimate what they already know
-
Teaching clarity — too much demonstration, not enough explanation
-
Nervousness while speaking
-
Limited situational awareness when task-loaded
-
Trying too hard to be “perfect” instead of being effective
What I tell them is simple:
You don’t have to be a flawless diver — you have to be a communicative one.
An instructor is not a performer — they’re a teacher.
IDC prep is about unlocking the potential you already carry — not transforming you into someone else.
