The PADI IDC Gili Trawangan program prepares divemasters from around the world to teach recreational scuba diving to professional standards. It uses a real-world, experience-based training model developed by Course Director Holly Macleod across 23 years in the global dive industry, with over 3,500 successful instructor certifications as the track record behind every intake.
The PADI Instructor Development Course is the professional training programme that certifies qualified divemasters to teach recreational scuba diving to the public. According to PADI International's official IDC standards, the course is structured around three core assessment areas, and a candidate must meet professional standards in all three to qualify for the PADI Instructor Examination.
On Gili Trawangan, Holly Macleod delivers each component in a sequence specifically designed to build candidate confidence progressively. You do not go into confined water on your first day and you do not sit theory exams before you have properly reviewed the material. The structure is deliberate, and it works. Visit the full PADI IDC guide and resource hub for complete programme details.
The academic component of the IDC covers five core dive theory areas: physics, physiology, decompression theory, equipment, and the Recreational Dive Planner or eRDPML. Daily sessions also cover PADI standards, dive planning, risk management, and teaching methodology. Written exams test each area, and you need to achieve 75% or above in all five to progress to the Instructor Examination. Holly's program includes focused review sessions specifically structured around the exam format so candidates know what to expect and how to perform.
This is the component most candidates find the most challenging when they first arrive. You already know how to perform every skill. In confined water sessions, you learn to break those same skills down step by step, demonstrate them clearly facing a student, and correct errors in real time. Holly evaluates your positioning, your teaching sequence, your student observation skills, and your problem management. The shift from diver to teacher is the core mental transformation of the IDC, and confined water is where it happens.
Open water sessions take place aboard Blue Marlin Dive's boat across Gili Trawangan's reef systems. You present skills in real open water conditions, managing real dive scenarios while Holly and any Instructor Examiners present evaluate your performance. Sea turtles, white-tip reef sharks, and excellent visibility are normal parts of the Gili Trawangan training environment. The open water presentations are where the full picture comes together, knowledge, skills, and teaching ability assessed as one integrated performance.
The IE is conducted by an independent PADI Instructor Examiner, not by Holly, which is the standard PADI process. It runs over two days and re-tests all three assessment areas under examination conditions. Holly runs a full mock IE cycle during the course so candidates know exactly what the examiner will look for. The standard her preparation targets is consistent performance above 90% in mock testing before the real IE begins. After passing, you register with PADI as an active instructor and your professional career begins.
There are PADI Course Directors across Indonesia, but the training environment matters as much as the instructor in front of you. Gili Trawangan is a small community island off the northwest coast of Lombok, about 30 minutes by fast boat from Lombok Airport or two hours from Bali.
What makes it different from mainland IDC locations is what is not there. No cars, no motorbikes, no airport traffic, no tourist resort strip pulling your attention away from preparation. The entire island is built around its diving community. When you are on Gili Trawangan for your IDC, diving is all there is. That level of immersive focus consistently produces better outcomes than a city-based course environment.
You wake up, you walk to Blue Marlin, you study or prepare your presentations in the morning, you dive in the afternoon. In the evenings, you go over your notes and prepare for the next day. That is the rhythm for 10 days on Gili Trawangan during an IDC, and it is a rhythm that works.
There are no commutes, no city noise, no decisions to make about restaurants or activities. The island puts you in a focused professional mindset almost immediately after arrival. Candidates who have trained in both city and island environments consistently report that the immersive environment of Gili Trawangan made a real difference to their performance.
The Wikipedia entry on Gili Islands describes Gili Trawangan as the largest of the three islands with the most developed diving infrastructure, which reflects 30 years of community investment in professional dive education at this location.

Holly Macleod's 3,500+ certified instructors now teach across every major diving region in the world. The PADI instructor credential is one of the most portable professional qualifications in the diving industry. Where you go after your IDC is up to you. The doors it opens are global.
The PADI Instructor Development Course is the professional training pathway that qualifies divemasters to teach recreational scuba diving. It is designed for active PADI Divemasters who want to take the next step in their diving career, whether that means teaching part-time at a local dive center, building a full-time career at an international resort, or eventually working toward Course Director status. Candidates come from all backgrounds and all nationalities. The only firm entry requirements are certification level, logged dive experience, and a current medical clearance.
A PADI Course Director is the highest professional certification in the PADI teaching hierarchy and is the only level authorised to conduct the PADI IDC. The Course Director designs the training structure, delivers all academic and practical sessions, evaluates candidate performance throughout the course, and prepares candidates for the independent PADI Instructor Examination. The experience and track record of your Course Director directly determines the quality of your preparation, which is why Holly's 23 years of consistent Platinum-level delivery matters when choosing where to do your IDC.
PADI awards Platinum status annually to Course Directors who certify the highest number of instructors while maintaining strong quality standards across their IDC program. It is a performance-based recognition that requires consistent results year after year, not a one-time credential. Holly Macleod has received this recognition for 13 consecutive years, which makes her track record one of the most verifiable in the Asia Pacific region. When comparing IDC options, Platinum status is the clearest available indicator of sustained delivery quality.
The course runs over 9 to 10 days. The opening days focus on knowledge development sessions, covering dive theory, PADI standards, and teaching methodology. Mid-course shifts to confined water presentations, where you demonstrate skills as a teacher rather than a diver. The final open water days involve boat sessions at Gili Trawangan's reef sites where you manage real teaching scenarios under assessment conditions. A mock IE cycle runs throughout the course. The PADI Instructor Examination follows immediately after the IDC over two days.
A PADI Open Water Scuba Instructor certification opens positions at dive resorts, liveaboards, dive centers, and professional training facilities across every major dive destination in the world. Graduates from Holly's program work in Thailand, Malaysia, the Maldives, Australia, the Philippines, the Caribbean, the Red Sea, and throughout Indonesia. Adding specialty instructor ratings after your IDC, particularly reaching MSDT status with five or more specialties, significantly increases both your hiring value and your earning potential in the international diving job market.
