Over the years, we've noticed some common misconceptions that show up again and again.
1️⃣ "My experience means I can skip the prep"
Some candidates assume their experience as a DM is enough to walk into the IDC ready to go. Spoiler: it's not. Teaching is a completely different skill set, and skipping prep - especially skill demonstrations, theory review, and physics refresh - almost always leads to unnecessary struggle in the first week. Preparation isn't about your ability to dive; it's about being ready to teach.
2️⃣ "Teaching is just explaining things well"
Explaining and teaching aren't the same thing. Great instructors don't just give clear explanations; they read the student in front of them, anticipate confusion, break skills into digestible steps, and adapt on the fly. If you think teaching is a talking exercise, the IDC will quickly show you otherwise.
3️⃣ "I know how to do the skills, so demonstrating them will be easy"
Doing a skill is not the same as demonstrating it. Instructor-level demonstrations are exaggerated, slow, controlled, and neutrally buoyant. Many candidates are surprised by how much rework their skill set needs to meet instructor standards. This is normal – just be ready for it.
4️⃣ "I'll be diving every day"
Compared to the Divemaster course, IDC candidates actually spend a lot less time in open water. Much of the IDC takes place in the pool, classroom, and workshops. This can catch candidates off guard, especially those expecting a diving-heavy schedule. The focus shifts from being in the water to learning how to teach in it.
5️⃣ "I just need to pass the IE"
The IE is the checkpoint, not the goal. If you go into the IDC focused only on passing the exam, you'll miss the real point: becoming someone your future students trust with their learning and safety. The best candidates focus on becoming great instructors, and the IE takes care of itself.
Coming in prepared, open, and ready to learn is the best way to make the most of your IDC. If you're considering when to take the next step, send us a message. We're happy to help you figure out where you're at.
