Scuba diving certification levels were developed to ensure maximum safety for divers. Each scuba diver possesses a certification card, confirming their qualifications. This is crucial for booking diving trips, selecting appropriate equipment, choosing the correct type of air, and even securing a job as a professional diver.
The scuba diving certification level you have indicates your knowledge, experience, and skills as acknowledged by various scuba training agencies. Some of the most well-known and respected organizations include CMAS, SSI, NAUI, and the world’s largest diving training entity, the Professional Association of Diving Instructors (PADI). By reading this article, you’ll gain insight into their respective scuba diving certification levels.
Recreational Scuba Diving Certification Levels

Although PADI offers the “Discover Scuba Diver Program” (DSD) for an initial introduction to scuba diving, it does not qualify as certification training. The PADI recreational scuba diving certification levels involve:
1. PADI Scuba Diver (Junior PADI Scuba Diver)
The PADI Scuba Diver certification highly suits individuals with limited time. gaining this certification means having sufficient knowledge to dive up to a maximum depth of 12 meters (40 feet). However, you must always be accompanied by a professional diver.
At this level, you cannot dive independently with just another certified diver having the same level, as professional supervision is required.
2. Open Water Diver (OWD) (Junior Open Water Diver)
This scuba diving certification level grants you independence. The primary goal of this course is to teach you how to manage both yourself and your scuba diving equipment underwater.
After completing this course, you are considered an independent certified scuba diver. This means you can freely choose your dive partner and go diving on your own without the need for professional supervision.
However, remember that there are depth restrictions at this level: 18 meters (59 feet) for adults and 12 meters (40 feet) for juniors.
3. Advanced Open Water Diver (AOWD)
The Advanced Open Water Diver (AOWD) certification is regarded as the third level in recreational scuba diving. This certification allows you to enhance your diving experience and broaden your knowledge in this area. The main difference of this level from the previous one is that as an AOWD, you can dive deeper, with a maximum depth of 30 meters (100 feet).

4. Rescue Diver
The Rescue Diver course is designed to enhance your rescue abilities. Upon completion, you’ll be a much safer diver, equipped to prevent issues and handle emergencies upon arising.
5. Master Scuba Diver
The Master Scuba Diver certification represents the pinnacle of recreational scuba diving credentials. PADI offers an extensive array of training programs designed to enhance scuba diving expertise. Among these are specialty courses in deep, night, or wreck diving, plus numerous others.
To qualify as a Master Scuba Diver, one must already be certified as a Rescue Diver and complete five of these specialty courses.
Professional Scuba Diving Certification Levels
