NOT all training agencies are the same, there are many differences in standards as applied to training and certification and many differences in training philosophy and delivery. Also we offer high quality materials, with flexible options and lower costs and on-going costs, etc.

The majority of International training agencies follow the guidelines from ISO / ANSI/EN to meet minimum International standards see our about standards page link here!

NOTE:  The comments below are from different sources of whom many are multiple agency professionals who have crossed over to ITDA, and where certified professionals with; CMAS / SSI / NAUI / PADI / ITDA / IDEA / BSAC / IANTD / TDI/SDI etc.  This is NOT the expressed view or opinion of the ITDA Management...  It is the ITDA management view that all of the major training agencies operate professionally and to high standards, following the ISO - ANSI/EN International standards.


PADI?  Professional Association of Diving Instructors

PADI programs may change from time to time but generally their basic diver program is the PADI Open Water Scuba Diver which is an International Diver certification.

PADI are also probably the largest scuba diver training agency in the world and as such they have a global network of affiliate diver training facilities around the World.

PRO's (For PADI)padi

Size of the organisation

Easy training and focus on fun diving

Good quality education and materials

Instructor Course is just 7 days on average

PADI has a Fast-Track System for Professionals and Specialist certifications

CONs for PADI (Against PADI)

Because of the size and popularity of PADI they have a lot of market saturation which may lead to certain areas or territories have multiple PADI dive schools in close proximity causing a "Price War" scenario for the private operators of these businesses.

This may "Appear to benefit the consumer", but to reduce operations costs operators may cut corners, including poor employment conditions and low wages for instructor etc.

Training very fast to certification from 3 days or less, with a minimum standard of just 4 Open Water Training dives and 5+ pool sessions (Depending on the training Centre!)

PADI have good International resources and representatives in many regions but are a United States (USA) based business.

CMAS?  Confederation Mondiale des Activites Subaquatiques

CMAS are traditionally a European body but operate worldwide. They have been training divers since 1958 and some very famous name where involved in the early days including the TV Celebrity;  Jacques-Yves Cousteau who was a founding member.

One Star Diver - "a diver who is competent in the safe and correct use of all appropriate open water scuba diving equipment in a sheltered water training area and is ready to gain open water diving experience in the company of an experienced diver.

Training dives may be up to 10 dives or more experience.

PRO's for CMAS

Long standing history of diver training on an International level since 1959.

CMAS are a serious training body and focus on safety and training for emergency situations.

Courses are recognised industry wide.

CONs for CMAS (Against CMAS)

Primarily a European body with limited International support.

Few actual CMAS training Centre's around the world.

CMAS Professionals tend to be multi-agency.

Up to 10+ Open Water dives required for certification.

CMAS are currently more focused on Free diving and International free diver training than on the traditional SCUBA Training... They also sponsor major competitions.


SSI? Scuba Schools International ssi

SSI Philosophy (Taken from their website) Knowledge replaces anxiety and fear with correct information. There are many ways you can start an SSI program offers traditional training, home study or online training. No matter which way you decide to take the program, it will be taught the same way  using the SSI Total Teaching System. During interactive review sessions, your SSI Dive Professional will teach you how 'land value' what you learn out of the water relates to 'water value' what you do with information in the water.

The best way to learn essential skills is through continuous and correct repetition. The goal of this repetition is to learn the skills so well that they can be performed automatically, and without conscious thought.

This is SSI's signature water training method: Comfort Through Repetition.

We believe it is vital to take plenty of practice time to develop the skills necessary to become a competent and comfortable diver.

Your SSI Dive Professional will lead you through a series of comprehensive skill exercises for you to practice until they become second nature.



Of the many 100's of other training agencies out there around the world are many national federations and Club Systems.  (ITDA also has an International Club System which follow the exact same certification standards as our International system.

The majority of people will learn to dive based on the recommendation of friends and family, and or as an act of convenience. (You are on vacation / holidays and there is a dive school at or close to your resort or hotel... This is very common!  So please do not be overwhelmed by the sheer number of agencies below:
