Then the Instructor Development Course Koh Lanta (IDC) is the course that will enable you to earn a living from diving and to see the world. Lanta Diver was the first PADI IDC centre on Koh Lanta. Since then we have been running successful IDCs on the island for the past 15 years. Our emphasis is on professionalism and is clear in all aspects of the dive centre. This professionalism continues right through our Instructor Development Course Koh Lanta & IDC Staff courses.

PADI Open Water Scuba Instructors and PADI Assistant Instructors are the most sought-after dive professionals around the world because they have completed the program that sets the standard for training dive professionals. You earn a PADI Instructor rating through hard work and commitment, but you are rewarded with a job that lets you share incredible underwater adventures with others – transforming their lives for the better and enriching yours.

Lanta Diver Padi Go Pro in Paradise location

The beautiful island of Koh Lanta in Thailand is the perfect environment for you to complete your PADI IDC. It is a relaxed island with beautiful beaches easily accessible for confined water and open water preparations. We have modern air-conditioned classrooms conveniently located in Lanta Diver main shop in Saladan. All confined water presentations are conducted in our private swimming pool with no disturbances or distractions.

The PADI IDC Koh Lanta

The Instructor Development Course (IDC) is made up of two parts – the Assistant Instructor (AI) course and the Open Water Scuba Instructor (OWSI) programme. Most dive professionals complete the entire IDC and go on to attend an Instructor Examination (IE), which is the final step to earn a PADI Instructor certification. Note that EFRI (Emergency First Response Instructor) is a prerequisite for becoming a PADI Instructor.

The PADI IDC teaches you to conduct all PADI core courses. You will be able to organise and present information, conduct skill development sessions and control open water dives. Basically, you become a better public speaker and get really good at demonstrating skills while watching out for student diver safety.

Key topics include:

  • PADI Standards and Procedures for courses you can teach with in-water workshops
  • Learning, Instruction and the PADI System
  • Risk Management and Diver Safety
  • The Business of Diving and your role as an instructor
  • Marketing Diving and Sales Counselling
As the course is more than two weeks, there is a wide variety of resorts to suit all budgets and preferences. Please contact Lanta Diver if you would like some recommendations and help with bookings.
