What is a Scuba Training Agency?

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

In the early stages of your recreational scuba diving training you will find that regardless of the agency, dive courses are more or less identical across the board. If you make the jump to the professional level, a whole new world will open up. You will quickly learn that 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!

PADI History

The Professional Association of Dive Instructors made a splash into the diving world in 1966 when it was dreamed up by two friends in Illinois who were concerned about the scuba diving standards upheld by certification agencies. 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 1960’s, 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.

Scuba Schools International (SSI):

Scuba Schools International is a retail-based organization. They are leaders in not only scuba diving but freediving, snorkeling and swimming as well. 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 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 Tillmans 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.

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. While each company has a similar vision, each one also goes about their instructing in a slightly different way. The most important thing to realize as a beginner diver or student furthering their knowledge, no matter which organization you end up choosing, the most important thing is to make sure you have FUN!

    Greetings from Idaho! I’m bored to tears at work so I decided to browse your blog on my iphone during lunch break.

      Hi Michael, if you have lost your card the best thing you can do is reach out to the agency which whom you are certified and ask them for a new one. They should have your information on file and it would just be a matter of printing a new card and sending it in the mail. Generally getting a new card costs anywhere from 20$ to 50$. Good luck!

    One should take a careful look at the training standards of the agency you wish to train with. PADI divers are not taught to deal with in water emergencies as other agencies do. NAUI will teach you very basic methods of submerged diver rescue including how to give rescue breathing while returning to the boat. It is important to me to know that my buddy could handle a problem should I have a situation that causes me to lose consciousness or stop breathing underwater.

    Not having any exposure to even the simplest rescue methods can result in two injured divers!

      Thank you for your input. You are absolutely right picking an agency means looking at their dive standards, and safety is a very important one. It would be great if PADI offered more safety oriented training earlier on.
