Thinking of becoming an instructor?

Reading this page could be one of the biggest turning points of your life. Becoming a PADI Instructor can lead you onto a path of new discoveries and adventures, or simply ignite a new passion.

We invite you to take that journey with us. Scubaversity is a passionate bunch of divers who love teaching diving. Our team are professional business owners who do this because diving is their way out of the normalcy of life.

About the PADI Instructor Development Course (IDC)

In the PADI System, PADI Divemasters train to become PADI Open Water Scuba Instructors in the Instructor Development Course (IDC) and qualify by successfully completing the PADI Instructor Examination (IE). Beyond the IDC and IE, instructor development continues through programmes ranging from Specialty Instructor training to IDC Staff Instructor courses.

There are three basic paths to instructor level, and all of them use the same IDC instructional system and performance requirements:

  • PADI Divemasters can complete the entire IDC as a single programme.
  • Alternatively, PADI Divemasters can take the PADI Assistant Instructor (AI) course, which covers key IDC components, then complete the Open Water Scuba Instructor (OWSI) programme with the remaining IDC components.
  • An instructor from a diver training organisation other than PADI can qualify as a PADI Open Water Scuba Instructor by completing the OWSI programme.

How the IDC works

You build your instructor-level knowledge and skills through independent study, plus live presentations and workshops run or supervised by a PADI Course Director and IDC Staff Instructors.

The IDC emphasises development, not testing. That makes it a low-stress environment where you can learn from your mistakes and concentrate on building knowledge and skill. You continue until you can reliably meet the minimum performance requirements to progress beyond the IDC.

The Instructor Examination (IE)

When you finish the IDC you attend the PADI Instructor Examination. The IE evaluates your teaching ability, dive knowledge, skill level, understanding of the PADI System, attitude, professionalism and the other attributes required of a PADI Instructor.

The IE runs over at least two days, conducted by a PADI Instructor Examiner using standardised, objective criteria. When you meet those criteria you earn the PADI Open Water Scuba Instructor rating.

Together, the development phase (the IDC, run by a PADI Course Director and instructor development staff) and the evaluation phase (the IE, run by PADI staff) make up one of the most comprehensive and demanding programmes in the dive industry.

Preparing for your PADI IDC

Preparing before you arrive is a vital part of the process and helps you get the most out of the course. Start as soon as you can, because there is more to cover than most people expect.

Theory and knowledge development

Once you have redeemed your access code you need to complete all 17 IDC eLearning presentations and their quizzes, and all 7 Diving Knowledge Workbook eLearning sections. This is where you focus your theory study, and it is time-consuming, so it must be finished before the IDC begins.

Theory exams

You receive practice exams with answer sheets and answer keys, plus a score sheet to track your progress. There is no time during the IDC to study or review theory, and if you cannot pass the entrance exam you cannot proceed to the Instructor Examination. For the RDP, practise with the electronic eRDPml rather than the traditional table or slate.

Standards and procedures

Get familiar with your Instructor Manual and Guide to Teaching (tab a printed copy for quick reference). For each course, know who can enrol, the required theory sessions, the confined water sessions and the number of open water dives, and keep practising the mock standards exams.

PADI apps and Project AWARE

Download the relevant PADI and AWARE apps from the Google Play Store or Apple App Store, create accounts if needed, and look through the AWARE programmes online.

Confined water skills

You must be able to demonstrate every PADI Divemaster skill slowly and clearly, highlighting the critical attributes, as if teaching someone for the first time. The IDC is not the time to practise hovering, so master it beforehand. Review your skill slates to check whether each skill is done in deep or shallow water and whether it has a time or distance requirement.

Rescue skills

Review and practise all Rescue Diver skills, and be comfortable with:

  • Rescue Exercise 2: Panicked Diver
  • Rescue Exercise 6: Surfacing an Unconscious Diver
  • Rescue Exercise 7: Exit and resuscitation, with both pocket mask and mouth-to-mouth

Other critical skills

Be able to demonstrate, explain and correct problems with:

  • Compass navigation (reciprocal headings)
  • Knot tying: sheet bend, bowline and two half hitches
  • Rigging and lifting an object underwater

It can feel like a lot, but the IDC is about development, and our staff team is here to guide you at every step. Ask us anything before you start.
