First you need to check that you meet the prerequisite requirements in order to participate in a PADI IDC, you must:

  • Be certified as a PADI Assistant Instructor, PADI Divemaster or as dive leader with another recreational diver training organization. 
  • Be at least 18 years old.
  • Be fit for diving and submit a medical form signed by a physician within the last 12 months.
  • Has been a certified diver for at least six months and logged at least 60 open water dives with experience in night, deep and navigation prior to beginning the Instructor Development Course. Have been a certified diver for at least 6 months & logged at least 100 dives prior to entering the Instructor Examination
  • Submit proof of CPR and First Aid training within the last 24 months.*

* For those whose CPR / EFR training has lapsed an update is included in the IDC Prep course or one can be arranged prior to or in conjunction with the IDC - contact Chris to see what can be scheduled for your IDC

The next thing is to Book your space on your Indepth PADI Instructor Development Course (IDC)

Once you are sure that the above requirements have been met you need to book your place on our Indepth PADI IDC program  - please contact us!

When you have received confirmation that there is still space you will need to pay the IDC Deposit. This can be done by via Pay Pal, Bank Transfer please contact us to find which payment method suits you best.

Once you space on your IDC program has been blocked we will then book your complementary airport pick up, arrange accommodation for you, and start ordering your PADI materials, organizing your IDC paperwork, assignments, etc...

Please contact us to make sure that there is still space available on the program you are interested in!

The final thing for you to do is to start your Indepth IDC Preparation:

1. Make sure you update your instructor manual with all relevant Training Bulletins

if you are in any doubt, please contact Chris

If you are missing any you can download them from the PADI Pro section of

2. PLEASE make sure that you are confident with your level of Dive Theory knowledge BEFORE the IDC!

PLEASE NOTE: Since the PADI Divemaster Course was revised in 2010 the Dive Theory taught on the PADI Divemaster Course is no longer the same as that on the IDC and the IE!

Because of this we believe the THREE DAY full-on IDC Prep that we have been running for the past 15 years, including full presentations on your Five Dive Theory Topics:  Physics, Physiology, Equipment, RDP Theory (RDP Table & eRDPml) and General Skills and the Environment and two Exams that we know you have not seen before has become even more valuable to you!

You also have the option of Dive Theory on-line to help you prepare for the IDC Prep & IDC

The best way to prepare for your IDC and IE Dive Theory is to buy, beg or borrow a copy of The Encyclopaedia of Recreational Diving and Diving Knowledge Workbook and work your way through it. You will have ample to keep you busy during the IDC without having to worry about dive theory questions such as and not still be worrying about Partial Pressures, M Values and Half-times, signs and symptoms of Mediastinal Emphysema etc...

You know when you have mastered it when you can not only arrive at the correct answer but also explain WHY each of the other answers is wrong!

During the IDC and IE the exams are available in over 20 languages. Should the exam not be available in your native language you will be credited with extra time.

Please note that exams other than English need to be ordered from PADI well in advance of the IE, so please let Chris know as early as possible.

3. Check what PADI materials you have ...

... and which you are missing as you will not only need the following materials but you will also be using them almost every day on the IDC and also on the actual IE itself.

Please review all your PADI materials: read through the revised Open Water manual, Adventures in Diving manual and PADI Rescue Diver manual. You might be surprised how much of the Dive Theory is actually in these manuals! You will no doubt once again be surprised at not only how much information is actually in these manuals and also just how much you have forgotten! Do you remember what Offshore and Longshore Currents are? No ? Chapter 3 of the OW manual : )

The majority of problems IDC Candidates experience on the IDC Prep when it comes to Dive Theory can actually be found in the Open Water Diver manual so it’s not a bad idea to go through the Quick Quizzes, Knowledge Reviews and Final Exam.

For your IDC and IE you will need the latest editions of the following PADI Diver level materials from courses you have already taken on your way to becoming a PADI Divemaster:

PADI Open Water Diver Manual

Recreational Dive Planner – RDP Table and eRDPML, including Instructions for Use booklets

NEW Adventures in Diving Manual

PADI Rescue Diver Manual

PADI Divemaster Manual

The Encyclopaedia of Recreational Diving

PADI Instructor Manual - latest version

EFR Primary and Secondary Care student manual

EFR Care for Children student manual

And you will need the following Instructor level materials:

IDC Pack

EFR Instructor manual

 4. Get wet!

Go Dive as much as possible, nothing replaces real life experience!

Assist your PADI instructor as often as you can. Practice all your skills, especially the 24 Skills of the PADI skill circuit. Concentrate especially on your buoyancy skills: Hovering and Neutral Buoyancy, Out of Air skills: Alternate Air Source and CESA (the controlled emergency swimming ascent) and your Remove and Replace skills: Scuba unit and Weight Belt, both at the surface and underwater.

Remember although an Open Water Diver can "do the skill", this is usually a long way off from the "demonstration quality" expected of an Instructor. You can also review the skills on the PADI Open Water DVD and the PADI Divemaster DVD.

When was the last time you DEMONSTRATED any of these?

And If possible get a PADI instructor to watch you perform Rescue Diver Exercise #7: "Unconscious Diver on the surface." You can review an excellent demonstration of this on The PADI Rescue Diver DVD or Rescue Diver Touch.

Again a demonstration and workshop of Rescue Diver Exercise #7 is included in the IDC Prep.

And of course all your dive equipment and make sure everything is serviced, up to date and ready for action.

5. Lastly relax!

Remember the more prepared you are the less of a workload you will have during the IDC leading to a more relaxed and enjoyable IDC!
