Completing PADI® courses at the various PADI certification levels and gaining PADI certification cards unlocks adventure in all corners of the globe. In addition, as a certified diver, you join a global community of ocean defenders that includes the Cousteau Family, Dr. Sylvia Earle, and millions of other divers around the world.

That being said, your underwater journey is entirely your own. After earning your first diving certification (such as the PADI Open Water Diver™), you’ll want to explore everything the ocean has to offer, but you may feel overwhelmed by all the options. That’s why we put together this comprehensive guide to PADI courses and certification levels. Explore the list below to find inspiration while planning your next scuba or freediving adventure.

Seek Adventure Your Way With PADI Courses

As divers, we are Ocean Torchbearers united by a passion to explore – and protect – our oceans. In short, the underwater world is our happy place, but for different reasons. Scroll through the PADI certification levels below to discover your diving destiny. As an experienced diver once said, “There’s a type of diving for everyone, you just have to find it.”

PADI Certifications

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 instructor, 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.

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 Open Water Diver course eLearning® program that will give you a taster of what to expect.

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.

Junior Open Water Diver™

Young adventurers aged 10-14 can participate in the PADI Junior Open Water Diver™ course and receive a Junior certification. The course entails the same knowledge as the original Open Water course but is better directed to a younger audience. Participants will complete theory practice (either in person or with eLearning®) and then in-water training. Once complete, Junior Open Water Divers will be certified to dive to 12 meters (40 feet) with a certified PADI professional.

Are you ready for your next PADI scuba certification? If you’re like most people, you want to avoid looking like a new diver. 

The fastest way 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 specialties to improve their buoyancy, underwater navigation, or underwater photos. The PADI course chart above shows the different scuba certification levels, as well as the many specialty subjects available. Please note, some specialties require an Advanced Open Water Diver certification as a prerequisite.

After the PADI Open Water Diver™, 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 an 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 the Open Water Diver course. Learn more about the difference between Open Water Diver and Advanced Open Water Diver.

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

PADI Junior Advanced Open Water Diver™

The PADI Junior Advanced Open Water Diver™ course allows young ocean lovers to further their underwater skills. Children aged 12-14 can undertake the course, gaining further knowledge and completing 5 speciality dives. These could include navigation, deep diving (up to 21 meters/70 feet), 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 specialised dive experience they have gained!

Take a Scuba Refresher Program

Don’t Let Your Scuba Skills Lapse

Life happens, and sometimes we can’t do the thing 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 (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.

Learn how to take great action-cam shots, discover if dry suit diving is right for you, or dive a shipwreck.

Improve Your Confidence and Become a Better Buddy

Who would you rather have as a dive buddy? An Open Water Diver or a Rescue Diver™? All other things being equal, most people would rather have a Rescue Diver as their dive buddy.

During the PADI Rescue Diver™ course, you’ll learn how to recognize potential problems and what to do in a diving emergency. You’ll have a surprising amount of fun role-playing victim and rescuer with other divers, and as a result, you’ll gain a lot of confidence in your diving skills.

Many divers tell us Rescue Diver was undoubtedly their favorite course out of all PADI courses. It’s challenging, rewarding, and also makes you a better dive buddy. With this in mind, read these important reasons to earn a Rescue Diver certification and one diver’s experience taking the PADI Rescue course.

The “Black Belt” of Scuba Diving

Above all, to become a PADI Master Scuba Diver™, you must:

Fewer than two percent of divers ever become Master Scuba Divers, so it’s rare to meet someone with this level of experience and scuba training. For this reason, Master Scuba Diver is sometimes referred to as “the black belt of diving.”

A scuba diving instructor teaching his Open Water Diver students how to dive in the ocean and become underwater ambassadors

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 underwater ambassadors who will be a voice for the ocean. 

Dive instructors also transform lives. They help students overcome their fears, take them on exciting adventures, and show them why we need to take better care of our ocean planet.

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 and some commonly held myths about becoming an instructor.

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 6 months
  • A minimum of 60 logged dives, or 100 if you will progress onto the Instructor Examination
  • A medical statement from a physician within the last 12 months
  • Emergency First Response Primary and Secondary Care (or equivalent CPR and First Aid) training within the last 24 months

Then, becoming a fully certified PADI Instructor consists of 3 parts:

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

You may be surprised to know: many people who complete the IDC don’t necessarily work as scuba instructors afterwards. 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.

Elevate Your Teaching Capabilities

With over 25 specialties to offer, PADI Specialty courses allow you to elevate your teaching style even further after becoming a PADI Instructor. Specialty Instructors become experts in different diving fields, inspiring students to undertake unique courses, too.

Additionally, these are attractive certifications to have in the scuba industry worldwide, such as being qualified to teach the PADI Ice Diver™ and Dry Suit Diver™ specialties, if you’re looking to work in extreme or cold climates.

Specialty courses are not only exciting for students but also thrilling for 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.

Other PADI diving courses you could become certified to teach include:

Tec 40 - TecRec - Technical Diving - Tec Sidemount

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. To begin with, 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 diver with the PADI Tec 40™ course.

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

Course Director

Join the Elite. Achieve the Highest Title.

Hovering at the top of the list of PADI® courses is Course Director status. However, 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 have certified over 150 students and completed over 250 logged dives. They must also have experience in assisting on IDCs and working at PADI Dive Centers and/or Resorts. 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, 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® Freediver™ Courses

Embrace Your Inward Power, Discipline, and Control

Freediving has become a popular way to explore the underwater world away from the burden of scuba gear and decompression limits. Instead, 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 PADI diving certifications or snorkeling experience to enroll in a Beginner Freediver course – just reasonable swimming skills and good physical health. If you’re over 12 years old, you can get certified and practice disciplines, such as dynamic, static, and constant weight freediving.

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. A growing community of PADI Mermaids are also using their mer-skills to advocate for ocean conservation or even become professional entertainers:

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 presently four recreational Mermaid diving certification levels.

  • Discover Mermaid™: A simple confined-water trial to give you a glimpse into a mermaid’s world
  • Basic Mermaid™: Introduces mermaiding fundamentals, from culture and gear to basic water skills
  • Mermaid™: Learn expressive water skills that set mermaiding apart from other types of diving
  • 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 a substantial number of male participants, and “mermaiding” is nowadays considered a gender-neutral term for this activity.
