Your First Scuba Diving Certification

Change Your Life. Become a Diver.

If you’re not a certified diver yet, we have plenty of information to help you learn everything you need to know about the PADI Open Water Diver course, the first PADI scuba diving certification. We’ve also put together a list of the most common questions new divers ask their scuba instructors, and we’ve debunked the top myths about scuba diving.

You may be wondering, “Is learning to scuba dive hard?” Or, maybe, you’re afraid of sharks

Don’t worry. It’s natural to be nervous. Do talk to your scuba instructor about your concerns, because they’ll be happy to answer any questions you have about your PADI Open Water Diver course and support you every step of the way. Here are some more tips on preparing for your first certification.

Not Sure if Scuba Diving Is for You?

Try it in a pool first – ask your local PADI dive shop about a Discover Scuba® Diving experience. Alternatively, sign up for Introduction to Open Water Diver, a free PADI eLearning® program that will give you a taster of what to expect during the full Open Water Diver course.

Here are a few other things to consider before booking your scuba lessons:

Whatever you do, don’t delay. The sooner you jump into your first PADI scuba diving certification, the sooner you’ll unlock a lifetime of Unfiltered experiences – from incredible marine encounters to new connections with friends. Your first step to learning to dive starts here.

PADI Junior Open Water Diver

Young adventurers aged 10 to 14 can participate in the PADI Junior Open Water Diver course and receive a Junior certification. The course entails the same skills and knowledge development as the original Open Water Diver course but is better directed to a younger audience. Participants will complete the theory portion of the course (either in person or with eLearning) and then in-water sessions.

Once certified:

  • Junior Open Water Divers aged 10-11 can dive to 12 meters (40 feet) with a parent, guardian, or PADI Professional.
  • Junior Open Water Divers aged 12-14 can dive to 18 meters (60 feet) with an adult certified diver.

After PADI Open Water Diver – What’s Next?

Are you ready for your next PADI scuba certification? If you’re like most people, you want to avoid looking like a new diver. Check out the PADI Certification Levels Chart above for a visual representation of the different PADI courses.

One of the fastest ways to improve your skills is to take additional scuba courses. About one in four divers enroll in the PADI Advanced Open Water Diver course next, while others take PADI Specialty Diver courses to improve specific skillsets such as buoyancy, underwater navigation, or underwater photography.

The PADI course chart above shows the different scuba certification levels for recreational diving, the steps to becoming a PADI Professional, and the many specialty subjects available along the way. Please note that some specialties require an Advanced Open Water Diver certification as a prerequisite.

PADI Advanced Open Water Diver

A Specialty Diving Sampler Platter

After the PADI Open Water Diver course, if you’re not sure which PADI diving course to take next, the PADI Advanced Open Water Diver course is a good choice. You’ll make your first deep dive with a PADI Instructor by your side, work on your buoyancy and navigation skills, and try three different types of specialty diving. Choose whatever interests you: photography and videography, wreck diving, fish identification, and so much more. Lastly, there’s no exam and very little reading compared to Open Water Diver.

Here is some more information to help you decide if this advanced scuba certification is right for you:

PADI Junior Advanced Open Water Diver

The Junior Advanced Open Water Diver course allows young ocean lovers to further their underwater skills. Children aged 12 to 14 can undertake the course, gaining further knowledge and completing five adventure dives. These include navigation, deeper diving (up to 21 meters/70 feet), and other specialty areas, like night diving, wreck diving, or peak performance buoyancy, under the guidance of an instructor. Once complete, young divers can thrive and dive with confidence thanks to the specialized underwater experiences they’ve had.

Take a Scuba Refresher Program

Don’t Let Your Scuba Skills Lapse

Life happens, and sometimes we can’t do the things we love as often as we’d like. If it’s been a while since you went scuba diving, PADI’s interactive online scuba refresher program, called PADI ReActivate®, is the perfect way to refresh the skills and knowledge learned during your Open Water Diver course. Plus, it’s free with a PADI Club™ membership.

Whether you want a thorough review of scuba diving fundamentals or just a few reminders, the online course tailors itself to you. You’ll review different diving scenarios and answer questions about dive planning, equipment, and other essential topics. Answer correctly, and you’ll move on to the next scenario. If you miss a question, the course will help you review important information you may have forgotten since getting your PADI scuba certification.

Then, schedule time with a PADI Professional to review your in-water skills. If you complete both the online and in-water portions of PADI ReActivate, you’ll get a new certification card with your ReActivated date on it. 

Are you ready for your next PADI scuba diving course or diving holiday? Review the signs you need a refresher, or test your knowledge by enrolling in ReActivate online. Our scuba diving refresher checklist will help you prepare to jump back in!

Above all, to become a PADI (Junior) Master Scuba Diver, you must:

Become a Scuba Instructor and Teach PADI Courses

Inspire Others to Seek Adventure and Save the Ocean

Scuba instructors are sometimes portrayed as vagabonds or beach bums, but in reality, they are passionate ocean defenders. Every day, scuba instructors around the world certify new Torchbearers who will be a voice for the underwater world. 

Dive instructors also transform lives. In a typical day, they’ll help students overcome their fears, take them on exciting adventures, and show them why we need to take better care of our ocean planet. For that reason, many say becoming an instructor was the best decision of their life.

How to Become a PADI Instructor

The first step to becoming a scuba instructor is enrolling in the PADI Instructor Development Course (IDC). Here are a few things to consider before taking the IDC:

Firstly, there are a few mandatory requirements to enroll in the IDC:

  • You must be a PADI Divemaster
  • You must have been a certified diver for more than six months
  • You must have a minimum of 60 logged dives, or 100 by the time you progress to the Instructor Examination
  • You must have a medical statement from a physician within the last 12 months
  • You must have completed Emergency First Response Primary and Secondary Care (or qualifying prerequisite for CPR and First Aid) training within the last 24 months

Then, becoming a fully certified PADI Instructor consists of three parts:

  • The PADI Assistant Instructor course (AI)
  • The PADI Open Water Scuba Instructor course (OWSI)
  • The Instructor Examination (IE)

You may be surprised to know that many people who complete the IDC don’t necessarily work as scuba instructors afterward. For instance, some divers take the course simply for the personal challenge and to learn skills that benefit them in office life. Others work as research divers, on public safety teams, or in the entertainment industry. Learn more about career opportunities for scuba divers, and read interviews with people who have full-time scuba diving jobs. Or, find out about other commonly held myths about becoming an instructor.

Advance Your Instructor Ranking

After becoming a PADI Open Water Scuba Instructor, you can keep moving up through the PADI Professional ranks by teaching and certifying different types of PADI courses (including specialty courses), assisting with IDCs, and attending PADI seminars. Learn more about PADI Professional Levels.

Specialty courses are not only exciting for students but also thrilling for PADI Instructors to become qualified to teach. In doing so, you become not only an inspiring role model for students but a sought-after dive professional for dive resorts and jobs in the marine industry.

Some PADI Specialty Diver courses you could become certified to teach include:

Course Director

Join the Elite. Achieve the Highest Title.

Hovering at the top of the list of PADI courses is Course Director status. While this title is one that almost every PADI Pro aspires to, Course Directors must first earn their place on the PADI Course Director Training Course (CDTC) to achieve this elite status. In due course, Course Directors are certified to teach the Instructor Development Course (IDC).

Without a doubt, the CDTC requires a high level of skill, so the requirements to enroll in this course are fairly intense. For example, candidates must be a solid PADI Master Instructor and EFR Instructor Trainer, and have over 250 logged dives. They must also have experience in assisting with IDCs and working at PADI Dive Centers and/or Resorts. You’ll also need to submit a business plan and pass a thorough interview process. The full requirements for the CDTC can be downloaded from the PADI Pros’ site.

Not only is being a Course Director an extremely desirable title in the dive industry, but this rating also comes with a huge sense of personal success. Becoming a Course Director is intense; however, it’s exciting, and it’s certainly respected.

PADI Courses for Technical and Rebreather Diving

Go Deeper. Stay Longer.

PADI Tec Diver courses attract experienced divers who want to go beyond the limits of recreational diving. Technical (or Tec) divers get to explore underwater caves, visit spectacular, untouched wrecks, and use cutting-edge dive equipment. Moreover, divers who learn to dive with a rebreather enjoy unparalleled animal encounters and dramatically longer dive times.

If you’re curious about technical or rebreather diving, then sign up for a Discover Tec or Discover Rebreather course. A PADI Tec Instructor will help you try tec diving equipment in a pool and show you a few basic skills. Then, if you want to keep going, you can complete your transition from recreational to technical diving with the PADI Tec 40 Diver course.

Or, if you’re not ready to go “full tec” straight away, consider trying sidemount diving instead. It’s a technical diving configuration that has recently become popular with recreational divers. Learn more about the benefits of diving sidemount.

PADI Freediver Courses

Embrace Your Inner Power, Discipline, and Control

Freediving has become a popular way to explore the underwater world away from the burden of scuba gear and no-decompression limits. While freediving, you’ll enjoy an unrivaled sense of peace and freedom for as long as you can hold your breath. And that’s not to mention the other benefits of freediving, like closer (bubble-free) marine life encounters, improved fitness, and reduced stress.

Moreover, you don’t need any prior diving certifications or snorkeling experience – just reasonable swimming skills and good physical health. If you’re over 12 years old, you can get certified and practice freediving disciplines, such as dynamic, static, and constant weight freediving, through a PADI Freediver™ course.

Once you’ve completed your first PADI Freediver course, you can then progress your skills and limits by moving on to PADI Advanced Freediver™ (ages 15+) and PADI Master Freediver™ (ages 18+).

A PADI Mermaid instructor teaches a student the skill of mermaiding underwater for which they will achieve a PADI certificate

PADI Mermaid Courses

A Unique Underwater Experience That Mixes Reality With Fantasy

Mermaid diving (or “mermaiding“) is a fun and rewarding passion that blends the essence of folklore with some basic techniques and equipment used in swimming, scuba, and freediving. It’s also a great workout! A growing community of PADI Mermaids is also using mer-skills to advocate for ocean conservation or even become professional entertainers, including Dada Li, Mara Restelli, and Brandee Anthony. Or, check out five more amazing mermaids that just might inspire you to take a PADI Mermaid™ course.

While mermaiding looks effortless (that’s part of the skill, after all), staying safe and elegant underwater calls for knowledge development and practical training. PADI Mermaid programs will help you do just that, and there are currently four recreational PADI Mermaid certification levels:

  • PADI Discover Mermaid™: A simple confined-water trial to give you a glimpse into a mermaid’s world.
  • PADI Basic Mermaid™: Introduces mermaiding fundamentals, from culture and gear to basic water skills.
  • PADI Mermaid: Learn expressive water skills that set mermaiding apart from other types of diving.
  • PADI Advanced Mermaid™: Progress your mermaiding skills while exploring the natural, open-water environment.

By the way, contrary to popular belief, PADI Mermaid is certainly not limited to women. There are many male participants, and “mermaiding” is nowadays considered a gender-neutral term for this activity.

FAQs About PADI Courses

You’ve got questions. We’ve got answers. Keep reading for more information on PADI courses.

Where Can I Take PADI Courses?

PADI courses are available worldwide at PADI Dive Centers and Resorts. You can find your nearest one using the PADI Dive Shop Locator.

Should I Use PADI eLearning or In-Person Learning?

Choosing between PADI eLearning and in-person learning depends on your preferences and schedule.

  • eLearning offers flexibility and convenience, allowing you to study at your own pace anytime and anywhere – even offline!
  • In-person learning provides direct instructor interaction and a structured environment, which can be beneficial if you prefer guided learning.

Both offer a combination approach to learning where you’ll complete dive theory sections followed by practical sessions.

Ultimately, both options lead to the same PADI certification, so you’ll be ready to start (or continue) exploring the underwater world!

How Much Do PADI Courses Cost?

Course costs vary depending on the location, the specific course, and the dive shop. Contact your local PADI Dive Center for detailed pricing, or see eLearning pricing.

How Long Do PADI Courses Take?

There’s no hard and fast rule. The time it takes to complete different PADI scuba certification levels depends on several factors, starting with the PADI dive course itself. On average, the Open Water Diver course takes 3-5 days. However, some PADI specialty courses can be completed in less than a day, and professional dive certifications can take weeks or even months to achieve.

The length of time is also influenced by your own pace. PADI eLearning lets you study dive theory in your own time, and all PADI certifications are based on performance rather than time, meaning your PADI Instructor will focus on your comfort and confidence, not how long it takes.

What If I Have a Medical Condition?

You should consult a physician before starting a diving course. Some medical conditions may require approval from a doctor to ensure your safety. You can find the PADI Diver Medical form on PADI.com.

Can I Book Course and Accommodation Packages?

In short, yes! PADI Travel® offers a variety of dive trip options, such as courses, dive resorts, liveaboards, and dive day trips to suit different preferences and vacation budgets. You can conveniently search the globe for and book exciting dive packages that include accommodation, meals, and multiple dives at famous diving destinations worldwide.
