Be Prepared!

That’s what my mum always told me. No matter what the situation was, she always said that it’s better to be safe than sorry.

And you know what?

She was right.

There have been countless times when I’ve wished that I had listened to her and taken a bit more time to prepare for what was ahead.

Prepare for your PADI IDC

And over the past 20 years, I’ve met so many people that wished they had done more preparation for their PADI Instructor Development Course.

By the time their IDC started, it was too late. 
They suffered unnecessary stress, and struggled to take in all of the concepts of the course.

Prior Knowledge for your PADI IDC

Many students believe that they should only focus on the PADI IDC material once the course has started.

However, you might be surprised to learn that your prior knowledge can have a significant impact on your ability to learn new information.


In fact, studies have shown that people who have some prior knowledge of a topic are more likely to remember new information than those who don’t.

This is because prior knowledge provides a framework for understanding new information.

Prior Knowledge

When you encounter new information, your brain automatically searches for connections to what you already know.

If it can’t find any connections, the new information is less likely to stick.

That’s why it’s often said that the best way to learn something new is to build on what you already know.


Prior Knowledge

So if you want to improve your chances of remembering what you learn, make sure to brush up on your prior knowledge before you start your PADI IDC.

What should I prepare myself for before taking my PADI IDC?

Well, to answer that question, let’s look at what’s involved in a PADI Instructor Exam.

The exam has 4 compartments and is usually run over 2 days. 

PADI IE Requirements

Theory Exams 

Physics, Physiology, Equipment, Diving skills and Environment, RDP
Total 60 questions

Standards Exam 
50 questions

Teaching in Confined Water

You’ll teach one skill in a swimming pool. Your presentation needs to cover: Briefing, Demonstration, Correcting Problems, Organising your class and De-briefing.

Teaching in Open Water

You’ll teach two skills. 
Again being marked on your briefings, Correcting Problems, Organising your class and De-briefing.

You will also demonstrate Rescue Exercise 7.

Prior Knowledge - Be Prepared

So, make sure that you’re ready for your PADI Instructor Training.
Being prepared for an upcoming course is a lot like packing for a trip. Just as you wouldn’t want to show up at the airport without your passport, you don’t want to start a class without the proper supplies and knowledge.


Before embarking on your academic journey, be sure to do your research and come prepared.

If you want to improve your chances of remembering what you learn, make sure to brush up on your prior knowledge before you start learning something new.

Also find out what materials you’ll need and make sure you have them.

Read up on the subject so you have a basic understanding of what will be covered.

And most importantly, don’t forget your sense of adventure! By approaching your studies with excitement and curiosity, you’ll be sure to get the most out of your experience.

Tips on what you'll need for your PADI IDC

PADI Materials

You’ll need to buy the 2024 version of the PADI IDC Crew Pack. 

You can buy this from any PADI 5 star IDC Centre. 

It includes a lot of online preparation that you need to complete before the start of your course. 

Dive Theory

PADI ‘s optional Dive Theory online program is available. 
If you complete the program it’s possible that you can get credit towards the theory section of your PADI IDC. 
CAUTION!!  You’ll still have to sit your theory and standards on your PADI Instructor Exam. 
So it’s really important that you’re fully up to speed in this area. 


You’ll need to have a medical certificate signed by a physician within the last 12 months stating that you’re fit to dive without any restrictions.

CPR and First Aid Training

You’ll need to have completed an EFR primary and secondary course within the past 24 months.

Emergency First Aid Instructor

To be in teaching status as a PADI Instructor, you’ll need to be an EFR Instructor. However, you can achieve this during your instructor training.
