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 Torchbearers 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 certification), 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.

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 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.

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 training. Once complete, Junior Open Water Divers will be certified to dive to 12 meters (40 feet) with a certified PADI professional or other certified adult (depending on their age).


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

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 PADI Specialty Diver courses 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 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 the Open Water Diver course. Learn more about the difference between Open Water Diver and Advanced Open Water Diver here.

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 PADI 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 speciality dives. These include navigation, deep diving (up to 21 meters/70 feet) and other specialty dives, 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 dive 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 thing we love as often as we’d like. If it’s been awhile 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.


PADI Specialty Diver Courses

Choose Your Own Adventure

Once you have your first PADI dive certification in hand, PADI Specialty Diver courses allow you to try different types of diving with an experienced scuba instructor by your side. Learn how to take great action-cam shots, discover if dry suit diving is right for you, or dive a shipwreck. Improve your search and recovery skills, or take a PADI Enriched Air (Nitrox) Diver course.

If you’re not sure which specialty to start with, take our specialty course quiz. Or, narrow down your options by picking from our list of the most popular PADI Specialty Diver courses.

PADI Rescue Diver

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 the 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 Diver course. 

PADI Junior Rescue Diver

The PADI Junior Rescue Diver course empowers young divers aged 12 to 14 with essential rescue skills and safety awareness. Just like the adult course, through engaging scenarios and hands-on practice, junior divers learn to recognize and respond to dive-related issues, assist others, and manage their own stress in challenging situations. This transformative course not only builds confidence and responsibility but also prepares young divers to be safer, more capable dive buddies.

Master Scuba Diver

The “Black Belt” of Scuba Diving

You may have heard the term “master diver” or “master scuba diver” and wondered what it means. Master Scuba Diver™ (sometimes referred to as “MSD”) is PADI’s highest level of recreational 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.”

To enroll in the Divemaster course, you must be 18 years old and have 40 logged dives as well as the following certifications:

PADI Junior Divemaster

The PADI Junior Divemaster course allows divers aged 15 to 17 to build leadership skills, assist instructors, and supervise dive activities under professional guidance. The course is structured similarly to the adult course but doesn’t include all the same material. At age 18, certified Junior Divemasters may become PADI Divemaster candidates and finish their training. Junior Divemasters must complete the remainder of the Divemaster course at this time.

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 six months
  • You must have a minimum of 60 logged dives, or 100 by the time you progress onto 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 equivalent 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 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.

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

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:

If these courses sound inviting, then check out the full range of specialties here.


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. 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 diving 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. 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 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 Inner 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. 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 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 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. A growing community of PADI Mermaids are also using their 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 presently four recreational Mermaid diving 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 a substantial number of male participants, and mermaiding” is nowadays considered a gender-neutral term for this activity.
