How to Become a Scuba Diving Instructor
Becoming a scuba diving instructor takes five stages: an entry-level certification, Advanced Open Water, Rescue Diver with Emergency First Response, the Divemaster rating, and the Instructor Development Course with the Instructor Examination that follows it. Certifications from other recognised agencies are accepted. From no certification at all the pathway runs 10 to 12 weeks of training. A certified Divemaster needs 14 days.
Find your starting point
Do you hold an entry-level scuba certification?
PADI Open Water, PADI Scuba Diver, or an equivalent from any recognised organisation.
Was that certification issued more than six months ago?
PADI requires at least six months between a first certification and the start of an IDC. It cannot be waived.
Do you hold an Advanced Open Water certification, or equivalent?
PADI Advanced Open Water, SSI Advanced Adventurer, or similar from any recognised organisation.
Do you hold a Rescue Diver certification, or equivalent?
Plus a current CPR and first aid qualification issued within the previous 24 months.
Have you logged at least 40 dives?
PADI requires 40 logged dives to begin Divemaster training.
Are you a certified Divemaster, or equivalent professional?
PADI, SSI or NAUI Divemaster, or a leadership rating from any recognised organisation.
Have you logged at least 100 dives?
You need 100 logged dives to be certified as an instructor, including documented night, deep and navigation experience.
The complete pathway, from a first dive to instructor.
No experience is needed to start. The full route runs 10 to 12 weeks of training and is the most common one for career changers. One constraint shapes the planning: an entry-level certification must be held for six months before an IDC begins, so getting certified early is the single most useful thing to do now.
The six-month rule applies — but the wait is usable.
No IDC can start until six months after an entry-level certification. Advanced Open Water, Rescue Diver and the Divemaster course can all be completed while that clock runs, so the waiting period costs nothing if it is planned around.
Next: Advanced Open Water, then three more stages.
The hardest constraint is already behind you. From here it is four courses, which most candidates complete in a single stay of 8 to 10 weeks.
Next: Rescue Diver, then Divemaster and the IDC.
Rescue Diver, Divemaster and the IDC with its examination take 7 to 9 weeks from here. A current CPR and first aid qualification within the previous 24 months is also required, and can be completed on arrival if it has lapsed.
Next: Divemaster, the last course before the IDC.
Divemaster training involves assisting real student courses, which is also how the dive count builds toward the Instructor Examination. From here it is 6 to 10 weeks to instructor.
Next: Divemaster — and the dives to reach 40 are included.
PADI requires 40 logged dives to begin Divemaster training. Unlike many centres, Go Pro Caribbean does not charge for the dives needed to reach that minimum: every dive required to get to 40 is included in the price.
From there Divemaster training runs through to certification, followed by the IDC and its examination.
Everything is in place except the dive count.
Every other requirement is met. Being certified as an instructor requires 100 logged dives, and that is the only outstanding item.
Pre-IDC Skills Preparation costs $150 a week and closes the gap: candidates log between 10 and 14 dives a week while practising demonstration-quality skills, assisting on courses and guiding fun dives. Two weeks typically adds 20 dives, and it is the most effective IDC preparation available.
Every prerequisite is met — enrolment is open.
The certifications are in place, the six-month rule is satisfied and the dive count is there. The IDC runs 12 days from 09:00 to 16:00, followed by the two-day PADI Instructor Examination held in Roatan. Courses run every month.
The five stages, and what each one requires
-
1
Entry-level certification
The pathway starts with an Open Water Diver certification, or an equivalent entry-level qualification from any recognised training organisation. The date on that card matters more than most people realise: PADI requires at least six months between it and the start of an Instructor Development Course, and no amount of diving in between shortens the wait.
Anyone certain about a professional career should get certified as early as possible, because the clock cannot be started retrospectively.
-
2
Advanced Open Water
Advanced Open Water extends the depth limit to 30 metres and introduces the range of diving a professional draws on later. Completing it in Roatan means moving straight into Rescue Diver with the same instructors in the same water, without a gap. Continuity matters in dive training: skills built in one place with one team produce a more rounded diver than the same courses assembled across different locations over a longer period.
-
3
Rescue Diver and Emergency First Response
Rescue Diver is the course most divers describe as the one that changed how they think underwater, moving attention from self to everyone else in the water. That shift is exactly what Divemaster and instructor training build on, which is why taking it immediately before Divemaster produces noticeably stronger candidates.
A current Emergency First Response primary and secondary care certification, issued within the previous 24 months, is required alongside it.
-
4
Divemaster
Divemaster is the first professional rating and a required prerequisite for the IDC. PADI sets 40 logged dives to begin Divemaster training and 60 to certify, but the number of weeks spent is the candidate's choice. Many take eight to ten weeks rather than the minimum, because more time means more dives, more teaching situations observed and a stronger foundation for the IDC. Go Pro Caribbean accommodates that; many centres run a fixed programme that ends when it ends.
Where the Divemaster course is taken matters more than most candidates expect. A dive centre built around producing instructors trains its Divemasters differently from one that does not run an IDC at all.
-
5
Instructor Development Course and Instructor Examination
The IDC runs 12 days and covers dive theory across six subjects, confined and open water teaching, PADI standards and presentation skills. It is followed immediately by the two-day PADI Instructor Examination, conducted in Roatan by an independent PADI Examiner who is not the course director. Pass the examination and the rating is PADI Open Water Scuba Instructor. To be certified as an instructor with PADI you also need to be an Emergency First Response Instructor.
Where the PADI instructor course is taken matters as much as where the Divemaster course was, and for a reason that outlasts the course itself: it decides who already knows you when you look for work. Coconut Tree Divers hires its own instructors from the people it trains, and a large number of Roatan's other dive centres prioritise instructors trained on the island — they know and trust the training because they know Will Welbourn, and an instructor trained here already knows the dive sites and how Roatan operates.
How long it takes, by starting point
The answer depends entirely on the certification already held, because what changes is the number of courses left to complete rather than the pace of any of them. The figures below are training time in Roatan for candidates working through the pathway without a break.
| Starting from | Courses remaining | Typical time |
|---|---|---|
| No certification yet | Open Water, Advanced, Rescue, Divemaster, IDC and IE | 10 to 12 weeks |
| Open Water Diver | Advanced, Rescue, Divemaster, IDC and IE | 8 to 10 weeks |
| Advanced Open Water | Rescue, Divemaster, IDC and IE | 7 to 9 weeks |
| Rescue Diver | Divemaster, IDC and IE | 6 to 10 weeks |
| Certified Divemaster | IDC and IE | 14 days |
Full pricing for each starting point is set out on the IDC cost page.
What you need before the Instructor Development Course
Seven requirements. Certifications from SSI, NAUI, BSAC and other recognised organisations are accepted throughout.
- Leadership ratingA PADI Divemaster rating, or a leadership-level certification from another recognised diver training organisation. Candidates arriving with a non-PADI leadership rating also complete the PADI Divemaster course dive rescue assessment.
- Six months certifiedAn entry-level certification issued at least six months before the course start date.
- 100 logged divesBeing certified as an instructor requires 100 logged dives, and the examination that certifies you begins the day after the course ends.
- Documented experienceNight diving, deep diving and underwater navigation, evidenced in the logbook.
- Emergency First ResponsePrimary and secondary care completed within the previous 24 months, or an equivalent qualification from another emergency care organisation.
- Medical clearanceSigned by a physician within the previous 12 months.
- Minimum age 18At the point of certification, without exception.
Pre-IDC Skills Preparation costs $150 a week and typically adds 20 logged dives over two weeks, alongside demonstration-quality skill practice and course assisting. Candidates log between 10 and 14 dives a week. Each requirement is covered in full here.
What you are qualified to teach after the examination
The Instructor Examination changes what a diver is permitted to do, not simply what they are called. On the Divemaster rating alone there is exactly one certification that can be issued independently: Advanced Snorkeler. Everything else a Divemaster does in the water is supervision, assistance or an experience programme run under an instructor's authority.
An Open Water Scuba Instructor teaches and certifies seventeen PADI courses and programmes on their own authority.
- PADI Scuba Diver
- Open Water Diver
- Adventure Diver
- Advanced Open Water Diver
- Rescue Diver
- Divemaster
- Advanced Snorkeler (Skin Diver)
- Discover Scuba Diving
- PADI Seal Team
- Bubblemaker
- ReActivate
- Discover Local Diving
- Peak Performance Buoyancy
- PADI AWARE Specialty
- Coral Reef Conservation
- AWARE Dive Against Debris
- PADI Snorkel Guide
Two entries on that list are PADI Membership ratings rather than diver certifications: Divemaster and Snorkel Guide. An instructor does not only certify divers — they certify professionals, including the rating they hold themselves.
Specialty Instructor ratings are earned separately and add further courses on top of these. Many candidates arrive determined to leave as a Master Scuba Diver Trainer, as though the rating itself were the prize. It is the wrong way round. What makes a newly qualified instructor employable is the range of specialties they can teach, because a dive centre hires the person who can run the courses it sells. Five Specialty Instructor ratings deliver that. Master Scuba Diver Trainer is the recognition that follows once those ratings are held and 25 certifications have been issued, which happens in the ordinary course of teaching. Earn the specialties and the rating arrives on its own.

Choosing the right IDC, and the right course director
At the end of the instructor development course there is an examination, and it is human nature to focus on passing it. That is not the real test. The real test is the first class taught as a certified instructor.
Dive centres actively seek candidates from course directors whose instructors arrive able to work. A new instructor with limited experience is not held back by that inexperience if the training was thorough, because employers already trust the standard. In Roatan's busy season from January to August, Will Welbourn is regularly asked by dive centres whether any recent candidates are looking for work.
The course director to look for is one who teaches candidates to be good instructors, not one who teaches them to pass the examination. Directors who optimise for examination scores often do so at the cost of preparing candidates for the situations that actually arise in a working week. Experience is what separates the two approaches. Will Welbourn's 100% first-time pass rate is qualified with “in the last ten years” for a reason: more than a decade ago he was one of those inexperienced course directors, with fewer than ten years and fewer than 100 IDCs behind him. He was teaching to the examination, not teaching people to think for themselves and reason through a problem as well as he could have, and when a novel problem came up some candidates were not equipped with the tools to succeed. Three candidates out of more than 500 have failed the practical examination at the first attempt, all in his early years, and he learnt more from those three than from any other candidate. A 100% first-time pass rate, full stop, can mean a course director who is very new and has not yet learnt those lessons. Real depth of experience is what to look for, and the number of IDCs a course director has personally taught is a better measure than the years qualified: look for one with over 100 IDCs behind them. Passing the examination is one thing; making a mess of the first few courses taught is how a new instructor loses the job.
The IDC is hard enough without adding cold water and poor visibility to the task load. There is an argument for training in the conditions you intend to work in, and it is a reasonable one — but it applies better to MSDT training than to the IDC. Qualify in warm, clear water where the teaching is the difficulty, then take further training somewhere colder if that is where the work will be.
How the Go Pro Caribbean IDC is run · What happens at the Instructor Examination
Finding work
On Roatan the first job usually comes through the centres that already know the training. Dive centres often ask Will Welbourn whether he has anyone who has just finished, and he passes on the details of recent graduates who are on the island and looking; a large number of the island's centres prioritise instructors trained here. Of the instructors Go Pro Caribbean trains who look for work on Roatan, more than nine in ten find it.
The curriculum vitae matters most for the jobs that come later, elsewhere, and on it most candidates undersell the experience they had before diving. Accountancy, plumbing, mechanics, medicine, hospitality, writing, design — all of it is relevant, and all of it should be on the page. Dive experience needs only a brief listing: number of dives, specialties held, where the diving was done. There is nothing to gain from making limited experience look like more than it is.
Frame the non-diving work so its relevance is obvious. Hotel or restaurant work is customer service, and dive centres hire for it. Anything involving computers, and particularly web or graphic design, is immediately useful because dive centres need their websites maintained. Mechanical knowledge matters — there is a great deal of equipment to keep running. Writing skills are valued, because centres need to reach customers online. Include a photograph that looks presentable.
Research every centre applied to and write a different covering message for each one. Their website and social accounts will say what they believe makes them distinctive; the message should demonstrate that it has been read and understood.
Start building an audience now
This sounds like odd advice for someone who is not yet a professional, which is exactly why almost nobody gives it.
Plenty of other people are considering the same career at this moment. Start a blog — one post a week is enough. Describe the decisions being weighed, which online resources proved useful, who was contacted and whether they were helpful. As the courses begin, describe those too: the dives that stood out, for good reasons or bad, and anything that would help somebody else, who may one day be considering the path you are treading now, make a better-informed decision. Will Welbourn hopes those posts end with many stories of the students you teach and the moments you shared with them — he wishes he had done that himself, to look back on now with pride.
Instagram is worth building alongside it. Diving is a visual industry and a dive centre's marketing runs on imagery, so a candidate who arrives able to shoot, edit and post is solving a problem the centre already has. An audience built around diving is a professional asset in a way a general following is not.
The reason this matters is that it compounds. A blog full of genuinely useful writing about becoming an instructor will appear in search results, which means a marketing channel is being built before there is anything to market. Prospective employers see that as an asset, because it demonstrates an understanding that marketing is part of the job. For anyone intending to work independently later, an established audience with real inbound links is the foundation of everything that follows.
If you arrive with an established audience — a blog with real readership, or an Instagram following built around your diving — say so when you get in touch. Documented training reaches people that advertising does not, and that is worth something to us.
A post about the free dive theory study notes is a reasonable place to start, and it helps other candidates find them.
Making a reasonable income
Most instructor work is commission-based: paid per course taught and per dive led. Some positions are salaried, and even then tips usually form a significant part of take-home pay.
Organisation is what separates instructors who earn well from those who do not. A well-planned course accounts for weather and logistics, is more enjoyable for the students, less stressful to run, and finishes on time. A badly planned one overruns, and the overrun is time that cannot be spent teaching them a specialty course as well, or attracting or teaching anyone else.
The job is not confined to the water. Most of it is diving, which is the point, but a dive centre needs customers in order to have anything to teach — and it needs its instructors' help getting them. Photographs taken and posted, customers tagged, conservation work done and documented. Tanks filled, equipment repaired, boats maintained, and a share of the cleaning and painting. The instructors who help most around the centre are the ones who get offered the better-paying work.
Where a centre sells equipment there is usually commission available. Wear what the centre sells while teaching, because students buy what they see being used, and learn the products properly — including their weaknesses. Sell customers the equipment that suits them rather than the equipment that pays best; the ones who are happy with what they bought come back for advice next time.
Frequently asked questions
How long does it take to become a scuba diving instructor?
It depends entirely on the certification you already hold. From no certification at all the pathway runs 10 to 12 weeks. From Open Water it is 8 to 10 weeks, from Advanced Open Water 7 to 9 weeks, and from Rescue Diver 6 to 10 weeks. A certified Divemaster needs only the 14-day Instructor Development Course and Instructor Examination. One rule binds every route regardless of experience: PADI requires at least six months between your first entry-level certification and the start of your IDC, so a beginner cannot compress the pathway into a single short visit no matter how quickly the courses are completed.
What do you need to become a PADI scuba instructor?
Eight things. A PADI Divemaster rating or a leadership-level certification from another recognised organisation. An entry-level certification held for at least six months. 100 logged dives to be certified as an instructor. Documented experience in night diving, deep diving and underwater navigation. Emergency First Response primary and secondary care completed within the previous 24 months. Medical clearance signed by a physician within the previous 12 months. And you must be 18 years old. To be certified as an instructor with PADI you also need to be an Emergency First Response Instructor. Certifications from SSI, NAUI, BSAC and other recognised agencies are accepted throughout.
What can you teach once you qualify as a PADI instructor?
Seventeen PADI courses and programmes, taught and certified on your own authority. On the Divemaster rating alone the only certification you can issue independently is Advanced Snorkeler — everything else in the water is supervision or assistance under an instructor. An Open Water Scuba Instructor teaches and certifies the full recreational range: Scuba Diver, Open Water Diver, Adventure Diver, Advanced Open Water Diver, Rescue Diver and Divemaster, together with Discover Scuba Diving, Seal Team, Bubblemaker, ReActivate, Discover Local Diving, Peak Performance Buoyancy, the PADI AWARE, Coral Reef Conservation and Dive Against Debris specialties, and Snorkel Guide. Two of those are PADI Membership ratings, so an instructor certifies professionals and not only divers.
How many logged dives do you need to become a scuba instructor?
100 logged dives to be certified as an instructor. The figure that binds is the one you hold on the day you are certified rather than the day you enrol, and because the examination that certifies you begins the day after the course ends, the two are effectively the same day. The PADI course standard for starting an Instructor Development Course is 60, but arriving at the course on that figure is unwise: the IDC is intensive, and a candidate still building basic dive experience is carrying that load on top of learning to teach. Dives logged beforehand are dives you are not trying to accumulate during the course, and you go into the examination with the training fresh rather than interrupted. Candidates short of 100 close the gap through Pre-IDC Skills Preparation, which typically adds 20 dives over two weeks.
What is the PADI six-month rule?
PADI requires at least six months between the date of your first entry-level certification and the start date of your Instructor Development Course. It cannot be waived, and it applies no matter how many dives you have logged or how quickly you completed the courses in between. It is the only part of the pathway that cannot be shortened by training harder. The waiting period is not dead time: Advanced Open Water, Rescue Diver and the Divemaster course can all be completed while the clock runs.
Can you become a scuba instructor without being a Divemaster first?
Not by skipping the leadership stage, but you do not have to arrive holding it. The Instructor Development Course requires a PADI Divemaster rating or a leadership-level certification from another recognised organisation, and there is no route that bypasses it. What you can do is complete it as part of a single continuous programme: most Go Pro Caribbean candidates arrive partway up the ladder and finish the remaining stages in one visit. If your leadership certification is from another agency rather than PADI, you will also complete the PADI Divemaster course dive rescue assessment.
Do your existing certifications have to be PADI?
No. Entry-level, advanced, rescue and leadership certifications from SSI, NAUI, BSAC and other recognised recreational training organisations are all accepted as qualifying prerequisites, provided you can document them. You will need to submit that documentation before the course begins. Holding PADI certifications is not required to become a PADI instructor, though familiarity with the PADI system is an advantage once you start teaching PADI courses.
How much does it cost to become a scuba diving instructor?
The total depends on your starting certification, because the number of courses between you and the Instructor Examination changes. Go Pro Caribbean publishes a price for every entry point, from complete beginner through to certified Divemaster, with the PADI fees itemised separately rather than folded into a single figure. Full pricing for each pathway is on the IDC cost page. See pricing for every starting level →
How much do scuba diving instructors earn?
Most instructor work is commission-based, paid per course taught and per dive led, with tips forming a significant part of take-home pay even where a salary is offered. Earnings therefore depend heavily on where you work and how much of the work you are given. On Roatan an instructor earns roughly $40 to $50 more per Open Water student taught than on Utila, and the island has over 50 dive centres recruiting locally against roughly 15 on Utila, so both the rate and the volume of available work tend to be higher. What instructors actually earn on Roatan, role by role, is set out on the instructor jobs and pay page.
