PADI vs SSI vs NAUI vs SEI

A Look at Some of the Top Scuba Diving Agencies

If you’re interested in becoming a scuba diver or expanding your dive training you’ve probably already done your research and stumbled across the wide variety of dive training agencies. Given that there are over 150 different certification agencies, for a first-timer, it can be very confusing trying to decide which organization to pursue your diving education with.

What is a Scuba Training Agency?

As a sport, scuba diving doesn’t have one centralized certifying or regulatory agency. Many agencies play a role in educating divers and regulating the sport as a whole. Over the years, these certification agencies have set the bar and developed training procedures and safety protocols as a standard for scuba divers everywhere.

In the beginning stages of your recreational scuba diving training, many divers will find that regardless of the agency, dive courses are relatively similar across the board, with a few minor variations. The more significant differences arise when divers jump to the professional or technical diving level, where some agencies do not recognize each other’s qualifications.

Important Note: While selecting a diving agency is an essential step in getting your dive certification, nothing is more important than having an instructor with experience, a good attitude and a keen mind for safety, even if this means going for your alternate choice of agency. The course will only be as good as the instructor who teaches it!

SEI History

Scuba Educators traces its roots back 60 years to the very first days of underwater exploration. This scuba diving certification agency stems from the YMCA scuba and skin diving program. In 2008, a group of former YSCUBA instructors Ken Nemeth, Dan Marelli and Tom Leaird banded together to create Scuba Educators – a new high standard scuba education agency with no connection to the YMCA. In 2011 the agency further expanded by purchasing and merging with the first SCUBA instructors college in the United States, the Professional Diving Instructors College (PDIC).

As a continuation of their dedication to quality scuba education, Tom Leaird now serves as Scuba Educators Director of Education alongside President Ben Brown and Vice President Cam Byrd.

PADI History

The Professional Association of Dive Instructors made a splash into the diving world in 1966 by two friends in Illinois. Scuba equipment salesman John Cronin and his friend Ralph Erickson, a swimming instructor and educator, developed PADI hoping to give future divers a chance to enjoy the underwater world by instilling solid, instructionally relevant training that would lead to more confident and recurring divers.

Early on, PADI grew slowly starting in restaurants and even the basement of Mr. Cronin’s home. PADI’s first milestone arrived in 1967 when the association introduced the first recreational diving certification requirements, the first advanced scuba diver course, and the first specialty diver program. In the late 1960s, the organization was still a struggling entity with only 400 members.

It took 20 years of hard work but finally by the late 1980’s PADI’s vision had grown into the leading scuba diver training organization in the world.

Some Interesting PADI Facts
  • Project Aware was established by PADI in 1989 as a global movement for scuba divers to protect our ocean planet.
  • For the past 20 years, PADI has averaged over 900,000 scuba diving certifications per year.
  • PADI offers recreational training and a few variations of technical dive training.

Bringing people together through communication and cooperation, SSI is a trusted name in the diving world that attributes their success to their high standards and focused methodology.

SSI is a strong believer in the scuba diving diamond:
  1. Knowledge – Being well versed in scuba diving information makes for safe and knowledgeable future divers.
  2. Skills – By gaining comfort through repetition, SSI hopes that safe scuba diving skills will become a student’s second nature.
  3. Equipment – Familiarizing yourself with the dive equipment will ensure you enjoy every minute of your dive.
  4. Experience – SSI seeks to encourage students to go above and beyond the minimum number of required course dives. The more dives a student can make the better they will become.

NAUI History:

The National Association of Underwater Instructors was brought to life by the perseverance of Al Tillman. While he worked as a sports director for the Los Angeles County Parks and Recreations, Mr. Tillman established a well-crafted training program geared towards certifying scuba and skin divers through the county.

In 1955, Al Tillman’s dream grew into the world’s first civilian diver training agency as he and a fellow peer from Scripps Institute of Oceanography, Conrad Limbaugh, held the first Underwater Certification Course (1U1CC). From there, thanks to the growing number of scuba certification request, Al and Conrad began granting Provisional Certificates to dive instructors across the L.A country.

As the interest and participation in the sport of recreational diving grew, in 1959 the National Diving Patrol was renamed the National Association of Underwater Instructors or NAUI as we know it today.

Some Interesting NAUI Facts
  • Al Tillman one of NAUI’s founding father, was the first instructor from this program
  • Captain Jacques-Yves Cousteau sat on NAUI’s first board of directors
  • NAUI offers both recreational and technical dive training.

SEI, PADI, NAUI or SSI?

Deciding on which agency to go with can certainly be a daunting task, and every certified diver will have their own opinion on which agency is best. Between SEI, PADI, NAUI, and SSI, while each company has a similar vision – to get people in the water scuba diving – each agency goes about its instructing in a slightly different way.

When considering which professional to use, take a look at your long term goals, learning style, instructor preference, and location. These are often key factors that influence a student’s agency choice. And at the end of the day, the most important thing to realize as a beginner diver, or student furthering their knowledge, no matter which organization you end up choosing, make sure you are safe and having FUN!

    I heard from a instructor in MN say that the owners of SEI arent even instructors. like how can you set standards when you aren’t even an instructor.

      Hi Thomas, I understand every diver will have their own opinion with regards to certification agencies and which one is best, however, SEI was created from the already existing YSCUBA program run by instructors Ken Nemeth, Dan Marelli, and Tom Leaird. I am curious… have you or your MN instructor taken any of their courses, looked at any of their manuals or reviewed any of the material?
