The Instructor Development Course (IDC) is made up of two parts – the Assistant Instructor (AI) course and the Open Water Scuba Instructor (OWSI) program. At DiveMania Scuba this is run in house with our very own PADI Course Director - David Kendrick-White and we offer a variety of options depending on your current rating and how you want to progress - see below

Successfully completing just the AI course results in a PADI Assistant Instructor qualification. When an AI is ready to progress, attending an OWSI program allows entry into an Instructor Examination to earn a full PADI Instructor rating.


A PADI Divemaster who has been a certified diver for six months may enroll in the PADI Instructor Development Course. You also need:


  • At least 60 logged dives and 100 dives to attend an IE.

  • Emergency First Response Primary and Secondary Care training within the past 24 months.

  • A medical statement signed by a physician within the last 12 months

  • You also need to be an EFR Instructor, but you can earn this rating during your training.


Over a minimum of seven days, the IDC teaches you to conduct all PADI core courses. You’ll be able to organise and present information, conduct skill development sessions and control open water dives. 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
