Scuba Schools International (SSI) is a for-profit organization that teaches the skills involved in scuba diving and freediving, and supports dive businesses and resorts. SSI has over 2,500 authorized dealers, 35 regional centers, and offices all over the world.[ citation needed ]
SSI was founded by Robert Clark in 1970. [1] SSI headquarters are in Fort Collins, Colorado, and it is owned by Concept Systems International, Inc. In 2008, it was acquired by Doug McNeese, owner of the National Association of Scuba Diving Schools (USA) until its merger with SSI in 1999, and Robert Stoss, manager of Scubapro and Seemann Sub. On January 1, 2014, SSI was acquired by HEAD, which also includes the Mares brand of diving equipment, HEAD NV, for €4.9m. [2] [3]
SSI offers internationally recognized recreational diver training programs - starting with snorkeling and entry level scuba diving courses up to instructor certifications. The most common programs are: SSI Open Water Diver (OWD) and Advanced Open Water Diver (AOWD). There are more than 30 different specialty courses. Dive leader training programs start with the Dive Control Specialist (who is qualified like Assistant Instructor) followed by Open Water Instructor and above.[ citation needed ] SSI's training program for children aged 8–12 years is called Scuba Rangers. [4] The training program for technical divers is called TechXR (Technical Extended Range) and includes decompression diving, trimix and other courses that exceed the limit for recreational divers.[ citation needed ]
SSI scuba certifications are recognized throughout the world (such as RSTC - Recreational Scuba Training Council, EUF - European Underwater Federation, CUA - China Underwater Association and others).[ citation needed ]
The main difference to other dive training organizations is that SSI instructors are only allowed to teach at SSI Dive Centers or SSI accredited dive clubs that adopt a franchise-like concept. [5]
SSI is a member of the following councils of the World Recreational Scuba Training Council - the United States RSTC, the RSTC Europe and C-Card Council (Japan). [6] [7] [8] It is also a member of the European Underwater Federation. [9] SSI obtained CEN certification from the EUF certification body in 2005. [10] It received ISO certification on June 1, 2010.
The SSI Training Standards outline the offered programs, their prerequisites and certification progression. [11]
In addition to the industry standard Open Water Diver (including Junior Open Water Diver for under 15s) qualification, SSI offers the following (which can be upgraded to Open Water certification with some additional training).
The Open Water Diver complies with Autonomous diver, ISO 24801-2. [11] The Autonomous diver level is variously described as the best, [12] and most popular, [13] introductory scuba qualification.
After Open Water certification, progression mainly depends on completing Scuba Specialty Programs and logging certain numbers of dives. [11]
Below are some of the speciality courses that can be completed as part of the above certifications.
The SSI Training Standards outline the professional qualifications and progression. [11]

Technical diving is scuba diving that exceeds the agency-specified limits of recreational diving for non-professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to a greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources.
Recreational diver training is the process of developing knowledge and understanding of the basic principles, and the skills and procedures for the use of scuba equipment so that the diver is able to dive for recreational purposes with acceptable risk using the type of equipment and in similar conditions to those experienced during training.
Recreational diving or sport diving is diving for the purpose of leisure and enjoyment, usually when using scuba equipment. The term "recreational diving" may also be used in contradistinction to "technical diving", a more demanding aspect of recreational diving which requires more training and experience to develop the competence to reliably manage more complex equipment in the more hazardous conditions associated with the disciplines. Breath-hold diving for recreation also fits into the broader scope of the term, but this article covers the commonly used meaning of scuba diving for recreational purposes, where the diver is not constrained from making a direct near-vertical ascent to the surface at any point during the dive, and risk is considered low.
Scuba Diving International (SDI) is a Scuba training and certification agency. It is the recreational arm of Technical Diving International, a technical diver training organization.
Technical Diving International (TDI) claims to be the largest technical diving certification agency in the world, and one of the first agencies to offer mixed gas and rebreather training. TDI specializes in more advanced Scuba diving techniques, particularly diving with rebreathers and use of breathing gases such as trimix and heliox.
ACUC, American and Canadian Underwater Certifications Inc. is an international recreational diving membership and diver training organization. Formerly known as the Association of Canadian Underwater Councils, it was formed as a not for profit collective of regional dive councils to create a national forum for their common interest and concerns. It soon began developing a training curriculum better suited to the Canadian conditions that many other training agencies neglected. It was later incorporated in 1986 in Canada by Robert Cronkwright. Cronkwright was a National Association of Underwater Instructors (NAUI) instructor from 1969 to 1971. In 1971 he crossed over to the Association of Canadian Underwater Councils and became a Training Director, Secretary/Treasurer and later Vice President of the Association (1972–1984). He was also Training Director for the Ontario Underwater Council (OUC) in the 1970s.
American Nitrox Divers International was founded by Ed Betts and Dick Rutkowski in 1988.
The International Diving Educators Association (IDEA) was originally established in 1952 as part of the Florida Skin Divers Association (FSDA). FSDA is a group of politically active Florida dive clubs. FSDA has been the voice of the diver since 1952.
A Diving certification or C-card is a document recognizing that an individual or organization authorized to do so, "certifies" that the bearer has completed a course of training as required by the agency issuing the card. This is assumed to represent a defined level of skill and knowledge in underwater diving. Divers carry a qualification record or certification card which may be required to prove their qualifications when booking a dive trip, hiring scuba equipment, filling diving cylinders or in the case of professional divers, seeking employment.
The Nederlandse Onderwatersport Bond, (NOB) is the national governing body for recreational diving and underwater sports in the Netherlands. It was founded in 1962. In 2008 there were 290 scuba diving clubs and schools with a total of 20.000 members. The NOB is a member of CMAS Confédération Mondiale des Activités Subaquatiques. The aim of the NOB is to develop recreational scuba diving in the Netherlands.
Diver training is the set of processes through which a person learns the necessary and desirable skills to safely dive underwater within the scope of the diver training standard relevant to the specific training programme. Most diver training follows procedures and schedules laid down in the associated training standard, in a formal training programme, and includes relevant foundational knowledge of the underlying theory, including some basic physics, physiology and environmental information, practical skills training in the selection and safe use of the associated equipment in the specified underwater environment, and assessment of the required skills and knowledge deemed necessary by the certification agency to allow the newly certified diver to dive within the specified range of conditions at an acceptable level of risk. Recognition of prior learning is allowed in some training standards.
Dive RAID International is a dive training organization which was founded in 2007 by Barry Coleman to support diver training for the Poseidon Mk VI Discovery Rebreather. It has since extended its scope to include open circuit scuba training and training for both recreational and technical diving sectors as well as snorkeling and freediving.
Autonomous diver is an international minimum standard for entry level recreational scuba diver certification. It describes the minimum requirements for basic training and certification for recreational scuba divers in international standard ISO 24801-2 and the equivalent European Standard EN 14153-2. Various organizations offer training that meets the requirements of the Autonomous Diver standard. A certification which corresponds to Autonomous Diver allows for independent diving with a dive buddy in open water. Most training organizations do not recommend exceeding a depth of 18 or 20 meters at this level of certification. After completion of this certification the training can be extended to a dive leader to ISO 24801-3 or an intermediate not defined by international standards.
Supervised diver specifies the training and certification for recreational scuba divers in international standard ISO 24801-1 and the equivalent European Standard EN 14153-1. Various diving organizations offer diving training that meets the requirements of the Supervised Diver. A diving certification which corresponds to the Supervised Diver allows for recreational diving under the direct supervision of a divemaster or recreational diving instructor in open water. Most diving organizations recommend not to exceed a diving depth of 10 to 12 metres. After the successful completion of a training equivalent to the Supervised diver, training can be extended to the Autonomous diver certification level.
Dive leader is the title of an internationally recognised recreational diving certification. The training standard describes the minimum requirements for dive leader training and certification for recreational scuba divers in international standard ISO 24801-3 and the equivalent European Standard EN 14153-3. Various organizations offer training that meets the requirements of the dive leader standard. Some agencies use the title "Dive Leader" for their equivalent certification, but several other titles are also used, "Divemaster" may be the most widespread, but "Dive Supervisor" is also used, and should not be confused with the very different status and responsibilities of a professional diving supervisor. CMAS affiliates certifications which meet the requirements of CMAS 3-star diver should meet the standard by default. The occupation of a dive leader is also known as "dive guide", and is a specialist application of a "tour guide".
The history of scuba diving is closely linked with the history of the equipment. By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon dioxide is filtered from the exhaled breathing gas, which is then recirculated, and more gas added to replenish the oxygen content. Closed circuit equipment was more easily adapted to scuba in the absence of reliable, portable, and economical high pressure gas storage vessels. By the mid-twentieth century, high pressure cylinders were available and two systems for scuba had emerged: open-circuit scuba where the diver's exhaled breath is vented directly into the water, and closed-circuit scuba where the carbon dioxide is removed from the diver's exhaled breath which has oxygen added and is recirculated. Oxygen rebreathers are severely depth limited due to oxygen toxicity risk, which increases with depth, and the available systems for mixed gas rebreathers were fairly bulky and designed for use with diving helmets. The first commercially practical scuba rebreather was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. His self contained breathing apparatus consisted of a rubber mask connected to a breathing bag, with an estimated 50–60% oxygen supplied from a copper tank and carbon dioxide scrubbed by passing it through a bundle of rope yarn soaked in a solution of caustic potash. During the 1930s and all through World War II, the British, Italians and Germans developed and extensively used oxygen rebreathers to equip the first frogmen. In the U.S. Major Christian J. Lambertsen invented a free-swimming oxygen rebreather. In 1952 he patented a modification of his apparatus, this time named SCUBA, an acronym for "self-contained underwater breathing apparatus," which became the generic English word for autonomous breathing equipment for diving, and later for the activity using the equipment. After World War II, military frogmen continued to use rebreathers since they do not make bubbles which would give away the presence of the divers. The high percentage of oxygen used by these early rebreather systems limited the depth at which they could be used due to the risk of convulsions caused by acute oxygen toxicity.
The following outline is provided as an overview of and topical guide to underwater diving:
Recreational scuba certification levels are the levels of skill represented by recreational scuba certification. Each certification level is associated with a specific training standard published by the certification agency, and a training programme associated with the standard., though in some cases recognition of prior learning can apply. These levels of skill can be categorised in several ways:
Professional Technical and Recreational Diving(ProTec) is an international diver certification agency based in Munich, Germany.
