NB DIVERS SEOUL · PADI CAREER DEVELOPMENT CENTER
Become a PADI Instructor in Seoul:
30 Days You’ll Remember Forever
The PADI Instructor Development Course isn’t about passing an exam. It’s the month that quietly changes how you see yourself — and the ocean.
Where Diving Stops Being a Hobby
You came for the fun.
Then you didn’t want the dive to end.

It usually starts quietly. One day the dive ends, you surface, and instead of feeling finished you feel the opposite — like you’ve only just begun. You find yourself watching the instructor more than the fish, wondering what it would take to be the calm person at the centre of someone else’s first breath underwater.
That feeling has a name. In diving, it’s the final step of the recreational path: the PADI Instructor Development Course, or IDC. It’s the difference between loving the ocean and being trusted to introduce other people to it.
Most people assume becoming an instructor is about collecting one more card. It isn’t. Done properly, it’s thirty days that rearrange how you communicate, how you handle pressure, and how you see your own potential. At NB Divers, that’s exactly what we protect — the depth of the experience, not the speed of the certificate.
Our Method
We coach.
We don’t simply teach.
There’s a real difference between teaching and coaching, and it shapes everything about how we run the IDC. Teaching is the classic picture: the expert writes on the board, you copy it down. Knowledge moves in one direction. It works, but it stops where the textbook stops.
Coaching is different. A Course Director’s job is to draw the answer out of you — to build your confidence, sharpen your instincts, and help you handle the situations no manual can fully describe. You try things. Sometimes you get them wrong. Then you stand up and try again, a little stronger each time.
We choose coaching on purpose, because the day will come when you’re the professional in the water and the unexpected happens. We want that version of you to think clearly, not just recite a page. With two resident PADI Course Directors and a maximum of three candidates per instructor, there’s always someone beside you, never a crowd in front of you.
What You’ll Actually Learn
Four weeks.
About sixty hours. One new version of you.

The IDC begins online with PADI eLearning, then moves into hands-on, Course-Director-led workshops in our Seoul classroom, pool and open water. Over roughly four weeks and sixty hours, you’ll practise teaching diving theory, demonstrating skills underwater, and presenting in a way that puts nervous students at ease.
Before you can start, PADI asks that you: be at least 18 years old, have been a certified diver for at least six months, hold PADI Divemaster (or a qualifying leadership rating from another organisation), carry a current EFR Instructor rating, and have logged enough dives to be ready — we’ll confirm your exact standing before you commit.
The course ends where it should: the Instructor Examination (IE), a two-day assessment run by a PADI examiner from the regional office. It covers five theory exams, classroom and confined-water teaching presentations, open-water skills, a rescue assessment, plus a 400-metre swim and a 10-minute tread. It’s demanding — and that’s the point. The card you earn means something precisely because the standard doesn’t bend.
Why NB Divers
A PADI 5-Star CDC that has trained instructors for over two decades.
NB Divers is a PADI Career Development Center — the highest training rating PADI awards, and the level qualified to develop instructors. Two resident Course Directors, each with more than twenty years in the water, run every IDC personally. We keep groups small on purpose, because confidence is built in conversation, not in a crowd.
Behind those numbers is a record we’re quietly proud of: over two decades with zero training accidents, an EFR-certified team that puts safety first, and dive professionals who communicate in English, Japanese and Korean. After your course ends, the conversation doesn’t — you can reach your instructors any time through KakaoTalk or WhatsApp.
Before You Come
Practical details, sorted — so you can focus on diving.
Finding us. Our centre is in Songpa-gu, southeast Seoul (Daejin Building, 2F, Baekjegobun-ro 7-gil), a short walk from Seokchon Station on Seoul Subway Lines 8 and 9. A taxi via the Kakao Taxi app is simple even with no Korean — just show the saved address.
Paying. Credit cards, including most foreign-issued cards, are accepted; you won’t need to carry large amounts of cash.
Staying in touch. Korea runs on KakaoTalk, but if that’s not your app, WhatsApp works perfectly — and the quickest way to reach us right now is the chat button at the bottom of this page.
Food. Songpa is full of options, and there are vegetarian, vegan and halal-friendly choices nearby — tell us your needs and we’ll point you to the right tables between sessions.
Questions & Answers
The things people ask before they commit.
Do I really need to become an instructor to take the IDC?
The IDC is the professional path, so yes — it’s designed for divers who want to teach. But “teaching” looks different than you’d expect. Many of our graduates simply wanted to understand diving deeply and discover what they’re capable of. The instructor rating is the result; the transformation is the reason people come.
My English is fine but my Korean isn’t. Will I keep up?
Yes. Our dive professionals communicate in English, Japanese and Korean, and we run the course so international candidates never feel lost. eLearning is completed in your language, and your Course Director works with you one to one.
How long does it take, and what’s the schedule like?
Plan for roughly four weeks and about sixty hours, combining online study with classroom, pool and open-water workshops. We share a sample timetable early so you can plan around work — many candidates train alongside other courses running at the centre.
What if I’m shy or not a natural presenter?
That’s exactly who coaching is built for. We start by simply reading from a prepared form, and finish with you speaking freely from just a few notes. Quiet, reserved people are often the ones who change the most over thirty days.
What happens after I pass the Instructor Examination?
You become a PADI Open Water Scuba Instructor, qualified to certify divers worldwide. From there you can keep growing toward Specialty Instructor, Master Instructor and beyond — and you’ll always have NB Divers behind you.

“From what we get, we make a living; from what we give, we make a life.”
That line — often credited to Winston Churchill — is the quiet heart of why we train instructors. Come build the kind of life you make by giving.
Learn it slow, keep it Forever.
