Starting your PADI Instructor Development Course (IDC) is one of the biggest steps in becoming a professional scuba diver. For many Divemasters, the IDC is where diving changes from a hobby into a real career.

One of the most common questions future instructor candidates ask is simple: “What actually happens during the IDC?”

The IDC is designed to prepare divers to safely teach and supervise scuba students while building confidence, professionalism, and real world problem solving skills.

At Pro Diving Indonesia in Nusa Penida, candidates train in active dive environments while gaining experience in tropical conditions, boat diving, drift diving, and real dive operations.


What Is A PADI IDC?

The PADI Instructor Development Course is the program that prepares certified Divemasters to become PADI Open Water Scuba Instructors.

The course focuses on:

  • Teaching techniques

  • Dive theory

  • Student control

  • Risk management

  • Skill demonstrations

  • Rescue abilities

  • PADI standards and procedures

After successfully completing the IDC, candidates attend the PADI Instructor Examination (IE), which is independently conducted by PADI examiners.



How Long Does A PADI IDC Take?

At Pro Diving Indonesia, IDC programs range from 18 days up to 12 weeks depending on the package and experience level of the candidate.

Some divers arrive already qualified as experienced Divemasters and complete an intensive instructor program. Others choose longer development packages that include:

  • Divemaster training

  • IDC preparation

  • Emergency First Response Instructor

  • MSDT preparation

  • Internship experience

  • Additional guided diving

Longer programs give candidates more time to improve:

  • Buoyancy control

  • Dive confidence

  • Teaching ability

  • Dive theory understanding

  • Professional awareness

The training schedule usually combines classroom sessions, confined water workshops, open water teaching, academic presentations, and real dive centre experience. Most days include both academic and in water training.

Classroom Sessions During The IDC A large part of the IDC focuses on understanding how to teach effectively.

Classroom workshops normally include:

  • Learning theory

  • Risk management

  • PADI standards

  • Course organisation

  • Teaching presentations

  • Dive physics and physiology

  • Problem solving techniques

Candidates also complete knowledge reviews, standards exams, theory workshops, and practice teaching presentations. Many candidates find this section more mentally demanding than physically demanding.



Confined Water Workshops

Confined water sessions focus heavily on demonstration quality and underwater teaching techniques.

During these workshops, candidates practise:

  • Demonstrating skills slowly and clearly

  • Teaching simulated students

  • Correcting underwater problems

  • Positioning themselves effectively

  • Maintaining buoyancy while teaching

One of the biggest differences between Divemaster level and Instructor level is learning how to explain and teach skills clearly to beginners. Being able to perform a skill personally is very different from teaching it professionally.


Open Water Teaching Workshops


Open water sessions simulate real student training dives.

Candidates practise:

  • Dive briefings

  • Site organisation

  • Student supervision

  • Underwater demonstrations

  • Problem solving

  • Rescue responses

  • Managing real dive flow

Training in Nusa Penida also exposes candidates to drift diving, boat diving, changing conditions, and real world dive logistics. These experiences help candidates become adaptable and confident instructors.


Dive Skills Assessment


During the IDC, candidates complete a full dive skills circuit.

Skills are evaluated on:

  • Demonstration quality

  • Control

  • Buoyancy

  • Clarity

  • Professionalism

The focus is not speed, but calm and controlled demonstrations that beginner students can easily understand. Good instructors make skills look simple and effortless underwater.



Rescue Assessments


Instructor candidates must also demonstrate rescue level abilities and problem management.

This includes:

  • Rescue scenarios

  • Surface management

  • Emergency responses

  • Stress management

  • Diver assistance techniques

Professional divers are expected to stay calm, organised, and effective during emergencies.


What Is The PADI Instructor Examination (IE)?


The Instructor Examination, commonly called the IE, is the final evaluation after completing the IDC.

The IE is conducted by independent PADI examiners rather than your own instructors.

The examination usually includes:

  • Theory exams

  • Standards exams

  • Confined water teaching presentations

  • Open water teaching presentations

  • Dive skills assessment

  • Rescue exercises

The IDC is specifically designed to prepare candidates for these evaluations.


Is The IDC Difficult?


The IDC is challenging, but manageable with preparation and commitment.

The most common challenges are:

  • Public speaking

  • Time management

  • Remembering standards

  • Demonstration quality

  • Teaching confidence

Most candidates discover that teaching workshops are more demanding than the theory itself. The key to success is preparation, consistency, and staying positive throughout the course.

Tips Before Starting Your IDC

Before beginning your IDC, it helps to:

  • Refresh dive theory

  • Practise buoyancy and trim

  • Review dive skills slowly

  • Improve confidence speaking in front of groups

  • Arrive well rested and prepared

Candidates with strong buoyancy and comfort underwater often progress much faster during teaching workshops.
