The IDC schedule DOES NOT include teaching Dive Theory or Demonstration Quality Skills from scratch.
You are expected to have a good grasp of both when you arrive.
Do you want to be a good instructor or a great instructor?
Benefit from our FREE IDC Prep Programme.
- Practice Theory Exams
- Prescriptive theory revision
- Practice Standards Exams
- Practice Skill circuits
- Access to EFR/PADI videos
- Access to PADI library
- Extra time to complete knowledge reviews
- Help with eLearning homework

ARRIVE TO DAHAB WITH TIME
We strongly advise you arrive in Dahab at least 5 days before the IDC/EFRI starts so you can settle in. The more time you give the IDC DIVE team to help you polish your skills and knowledge, the better instructor you will be.
On the other hand, candidates who arrive just a few days before the IDC with only a basic grasp of theory and rusty demonstration quality skills will find themselves waking up early and studying till very late.

1. Dive Theory
We recommend that you start studying Dive Theory at least two weeks before arriving in Dahab.
Dive Theory is divided into five sections:

Use the Encyclopedia of Recreational Diving. Look below to find our recommendations on what sections to review for instructor level dive theory
Check out our FREE Dive Theory Study Guides published on this website.

3. IDC eLearning
Complete all 16 IDC e-Learning segments. These are mandatory and must be completed before attending each IDC workshop.
Save yourself over 20 hours of study during an already busy course. Contact us to get your Crew Pack and get started today!

IDC e-learning covers:
What they are, how to find them, stay informed, interpret, and follow them.
Understanding PADI instructor expectations, duty of care, professional judgment, and application.
Familiarise with the instructor’s perspective on the courses.
Promote yourself as an instructor using PADI materials to market and sell diving.

How to study
Pay attention to the answers you got wrong. Now you know the gaps in your Knowledge.
If you pass my IDC, I’ve made the decision that you are ready to teach students. PADI just wants to check they agree. That’s why I see the IE as a test of my judgement and training rather than an examination of my instructor candidates
Start from scratch
If you feel you need to start from scratch, concentrate on these areas of PADI’s Encyclopedia of Diving.
The history section is of interest but not necessary for theory exams.
Relates to – Skill & The Environment Section Necessary reading: Currents, waves and tides Other topics in Skill & The Environment Section, can be found in the Adventures in Diving & Rescue Manuals
Cylinders / tank valves / Regulators / AASs / SPGs & instrumentation SCR & CCRs
This chapter covers a lot of interesting and basic knowledge that instructors should understand. Areas of focus are: Water & Heat; Charles’ Law – rough formula 1 degree Celsius = 0.6 bar Heat Transmission; Water & Light; Water & Sound Buoyancy (Archimedes’ Law)/ Pressure (Boyle’s Law) /Heat (Charles’ Law); DCS (Henry’s law) & Gases (Dalton’s Law) – Basically the whole chapter!
Once again, some great basic knowledge here. Areas for focus are: Blood & Heart / general body systems / Responses to Breathing with Equipment / Circulatory & Respiratory Problems / Oxygen Exposure / Responses to Thermal Changes / Pressure Changes on Air Spaces Decompression Physiology (Decompression Theory Session) A large section but I suggest you read it all.

You can also use the Divemaster Manual’s section on this subject as a more condensed version for study 41-79.
You also need to be familiar with the eRDPml and the RDP. Use the Instructors for Use.
