Scuba diving PADI vs SSI vs NAUI vs BSAC

PADI vs SSI vs NAUI vs BSAC what are the differences. There are a number of differences between the scuba diving agencies, but firstly all are accepted world-wide. Starting with PADI, they would be considered as a ‘training agency’ trading for a profit. Compared to BSAC at the other end of the scale would consider themselves to be more of a ‘scuba club’, and is a non-profit organisation. SSI is similar to PADI, as it’s also a profit making dive organisation, whereas NAUI is similar to BSAC, as it is also a not for profit scuba diving organisation.

Before I explain the differences between PADI, SSI, NAUI and BSAC, let’s take a look at what each one stands for, starting with PADI.

What does PADI stand for?

PADI stands for the Professional Association of Diving Instructors, where their motto is “Under every rock, around every reef, a new discovery awaits“.

PADI’s claim is there are 27 million divers that started with them. The PADI diving agency has been around since 1966.

The organisation is a recreational diving membership and diver training organisation. It was founded by John Cronin and Ralph Erickson.

The two founders were both scuba instructors and divers who were friends in the state of Illinois, U.S.A. Their goal was to give more people a chance to enjoy the underwater world. They wanted to offer relevant, instructionally valid scuba diving training to create confident scuba divers who dive regularly.

PADI is a business for profit organisation and their corporate headquarters located in Rancho Santa Margarita, California, USA.

What does SSI stand for?

SSI stands for the Scuba Schools International. SSI started in 1970 and has more than 30 Service Centers. The organisation is represented in more than 110 countries world-wide with over 2,800 International locations.

What does NAUI stand for?

NAUI stands for the National Association of Underwater Instructors. NAUI was set up by Albert Tillman and Neal Hess in 1959. Their headquarters are in Florida in the US.

NAUI’s motto is “The Definition of Diving“, but also they promote “Dive Safety Through Education“.

What does BSAC stand for?

BSAC stands for the British Sub Aqua Club. BSAC started in 1954, so has been around for much longer than most diving organisations, SSI included (and PADI for that matter). The British Sub Aqua Club has around 1,100 independent dive clubs and 400 diving schools worldwide that teach scuba diving.

BSAC has taught the best which includes the likes of Princes and one of my favourite people in the world, Sir David Attenborough. In fact when I interviewed Richard Bull Rock-band star and professional scuba diver, he told me how he’d certified Sir David.

BSAC’s motto is quite simple and is “Dive with us“.

Is NAUI better than PADI? or is SSI better than PADI or is BSAC better than PADI, NAUI or SSI?

The best advice to take when choosing your scuba diver certification is to choose the trainer first over the diving organisation. Whichever scuba diver training you take, be it PADI, SSI, NAUI or BSAC, you’ll enjoy it and will be safe.

So whether you choose PADI vs SSI vs NAUI vs BSAC really doesn’t matter. It really only boils down to whether there’s a PADI centre, an SSI centre, a NAUI or a BSAC centre near you.

Or which diving agency training centre is where you happen to be on holiday at the time you’re looking to get certified as a scuba diver.

Can you switch between PADI vs SSI vs NAUI vs BSAC and is each certification recognised by the others?

The question about whether SSI is recognised by PADI or visa versa and PADI recognised by NAUI or if BSAC is recognised by PADI or SSI, or whatever combination you choose, the answer is yes, all these diving agencies recognise each other.

But whilst they recognise each other’s certifications, they are different. This means you can’t switch agency whilst you’re in the middle of your training or initial certification.

The important thing to understand is that when you’re ready to move to the next certification level, PADI, SSI, NAUI and BSAC all recognise each other’s certifications as “equivalent” or “similar” training.
