PADI vs NAUI vs SSI – Which One to Choose?

Every diver knows that certification is essential to explore the underwater world safely. There are many scuba certification agencies out there, but the three big names in the industry are PADI (Professional Association of Diving Instructors), NAUI (National Association of Underwater Instructors), and SSI (Scuba Schools International). If you’re planning on becoming a certified scuba diver, you might be wondering which one to choose.

In this blog post, we’ll compare PADI, NAUI, and SSI based on various factors to help you make an informed decision.

Course Curriculum

All three agencies offer similar courses, but PADI has the most extensive course curriculum. PADI courses are structured to take you from a beginner to an advanced level effortlessly. NAUI courses are slightly more challenging but are designed to make divers more competent rather than passing a test. SSI courses, on the other hand, provide a more flexible schedule, self-paced agenda, and online study materials. Therefore, choose an agency whose course curriculum aligns with your diving goals.

Instructors Quality

Your instructor quality is crucial for you to have an enjoyable and safe diving experience. All three agencies have certified instructors with excellent skills and experience, but some divers prefer PADI instructors since they have the most extensive network. However, when it comes to training, it is the individual instructor that matters most. Thus, you should do some research and read reviews before choosing an instructor.

Course Flexibility

PADI courses are famous for their flexibility, and that’s why it’s often the preferred option for divers with busy schedules. PADI e-learning options allow students to finish coursework at their convenience before attending a certified training session. NAUI, however, has an instructor-led teaching method, which means more interaction between students and instructors. SSI provides a balance between the two; it offers online classes, but it also necessitates in-person training so that students can interact with the instructor and ask questions.


Both PADI and NAUI are recognized globally and widely accepted almost anywhere you go. SSI is new in the market, but their certification is also accepted at most dive locations. However, if your plans involve scuba diving jobs, PADI certification might give you an advantage, as it is more widely recognized and known in the industry.


Course fees vary based on location, but on average, PADI courses are the most expensive, followed by NAUI, and then SSI. Nonetheless, SSI courses’ fees can vary more due to their flexible structure. Moreover, some regions might provide discounts or additional packages, so make sure to check the prices in your area. Basic course fee will start from $450-$600, and all inclusive package will cost around $1000-$1300 depending on locations


PADI, NAUI, and SSI are excellent choices for scuba diving certification agencies. All three have similar courses, but they differ in their teaching approaches, course flexibility, and pricing. So the choice to select one over the others will come down to your individual diving goals, budget, preferences, and future career plans. Before deciding, do comprehensive research and talk to divers certified by each agency or consult with dive centers in your region. Ultimately, remember that the certification agency is a stepping stone to your scuba diving experience, and the success of this rests on you and how much effort you put into it.
