Certification
The Instructor Development Course is the bridge between leading dives as a Divemaster and certifying new divers as a PADI Open Water Scuba Instructor. PADI splits it into two parts: Assistant Instructor, then the Open Water Scuba Instructor programme. Many candidates do both back-to-back, and some pause after AI and return later when their logbook and finances catch up.
IDC is not more diving for fun. It is weeks of lesson planning, teaching presentations, standards quizzes and being watched while you demo scuba skills to divers who are pretending to be hopeless, because real students will be. Your Course Director's job is to make you ready for the Instructor Examination, not to hand you a card for showing up.
Typical format is two to three weeks intensive or a longer part-time schedule, followed by the IE. Centres on adventuro run IDCs in quarries, on coasts and in warm-water holiday hubs. Training in UK water builds cold-water teaching habits early. Training abroad gives warmer open-water presentation days. Both are valid if the centre teaches to PADI standards.
Plan for IDC plus Instructor Examination — typically two to three weeks full-time, or several weeks part-time, plus IE days.
Internship-style placements over four to twelve weeks are available at some centres for candidates who want more teaching hours before the IE.
IDC assessment is continuous under your Course Director; final certification requires passing the Instructor Examination.

Find activitiesIt is PADI's structured instructor training programme, comprising Assistant Instructor and Open Water Scuba Instructor segments. Successful completion plus a passed Instructor Examination earns OWSI certification.
On adventuro this is listed as Scuba Instructor Development Programme — the PADI course name is Instructor Development Course (IDC).
IDC is the training programme (AI plus OWSI). OWSI is the final instructor rating you earn after IDC and a passed IE.
Think of IDC as the course you take and OWSI as the job title on your plastic card.
Divemaster, six months certified, 60 dives to start and 100 for the IE. Current EFR, medical clearance, and EFR Instructor (often during IDC).
Leave a comment when you book if you are short on logged dives — some centres help you build counts before IDC starts.
Typically two to three weeks intensive, or longer part-time. Add two to three days for the Instructor Examination.
Internship formats over several weeks spread teaching practice but extend the calendar. Choose based on how ready you feel, not just holiday dates.
Yes. AI is a valid professional rating — you can teach certain components and assist on courses. To certify Open Water students you must complete the OWSI segment and pass the IE.
Some candidates pause after AI, work as an assistant through a season, then return for OWSI.
Different hard. Less towing and more talking. The challenge is consistent teaching under observation, not just diving well yourself.
Candidates who struggled with rescue stamina sometimes thrive in IDC; strong divers who hate public speaking sometimes struggle. Both can succeed with preparation.
IDC includes ongoing evaluation by your Course Director. The IE adds written standards and theory exams plus practical teaching stations assessed by PADI Examiners.
Revise dive theory before you arrive. The physics you scraped through as a Divemaster comes back in detail.
Normal. IDC is designed for candidates who have never taught — you practise on other candidates and staff before real students.
Leave a comment when you book if public speaking worries you. A good Course Director coaches delivery, not just standards.
Work as a PADI Open Water Scuba Instructor at dive centres worldwide, teach core courses, and build toward specialty instructor ratings and career advancement.
First jobs often start with DSDs and assist roles even with a fresh OWSI card. Expect to earn experience, not just a salary, in year one.
Full scuba kit, logbook, all certification cards, medical clearance and note-taking gear. Teaching slates and IDC materials are usually specified by your Course Director.
Warm layers for long pool days and a laptop for lesson planning save comfort and time.
adventuro lists PADI IDC centres with published dates, Course Director profiles and package details. Compare IE support, internship options, EFR Instructor inclusion and application fee transparency.
Training where you plan to work builds site knowledge and employer relationships. Destination IDCs offer warmer open-water teaching — both are valid paths to the same examination.
