The National Academy of Scuba Educators, also known as NASE Worldwide, is a recreational scuba training organization which was founded in Texas during 1982. [1] [2] [3] In February 2011 NASE re-launched its image and developed new standards and practices. [4] NASE's training program consists of three streams - recreational scuba diving, technical and professional diving in the recreational field (instructors and divemasters). [5] [6] [7] NASE operates in Colombia, Chile, South Korea, Russia and the United States of America. [8] It has a program of resort and dive center recognition with businesses recognised in the following countries - Barbados, Canada, Fiji, Honduras, Malaysia, and the Turks and Caicos Islands.

Scuba diving Using bottled air to swim underwater

Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba), which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Although the use of compressed air is common, a new mixture called enriched air (Nitrox) has been gaining popularity due to its benefit of reduced nitrogen intake during repetitive dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a regulator. They may include additional cylinders for range extension, decompression gas or emergency breathing gas. Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases. The volume of gas used is reduced compared to that of open circuit, so a smaller cylinder or cylinders may be used for an equivalent dive duration. Rebreathers extend the time spent underwater compared to open circuit for the same gas consumption; they produce fewer bubbles and less noise than open circuit scuba which makes them attractive to covert military divers to avoid detection, scientific divers to avoid disturbing marine animals, and media divers to avoid bubble interference.

Texas U.S. state in the United States

Texas is the second largest state in the United States by area and population. Geographically located in the South Central region of the country, Texas shares borders with the U.S. states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the southwest, and has a coastline with the Gulf of Mexico to the southeast.

Recreational diving Diving for the purpose of leisure and enjoyment, usually when using scuba equipment

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 greater levels of training, experience and equipment to compensate for 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.


EUF Certification

NASE Worldwide Inc. obtained CEN certification from the EUF certification body in 2008 and was re-certified in February 2016. [10]

Professional Association of Diving Instructors Recreational diver training and certification agency

The Professional Association of Diving Instructors (PADI) is a recreational diving membership and diver training organization founded in 1966 by John Cronin and Ralph Erickson. Cronin was originally a NAUI instructor who decided to form his own organization with Erickson, and to break diver training down into several modular courses instead of the single universal course then prevalent.

A Divemaster (DM) is a recreational diving role which includes organising and leading recreational dives, particularly in a professional capacity, and is a qualification used throughout most of the world in recreational scuba diving for a diver who has supervisory responsibility for a group of divers and as a dive guide. As well as being a generic term, Divemaster is the title of the first professional rating of many training agencies, such as PADI, SSI, SDI, NASE, except NAUI, which rates a NAUI Divemaster just under an Instructor but above an Assistant Instructor. The Divemaster certification is generally equivalent to the requirements of international Standard ISO 24801-3 Dive Leader.

The National Association of Underwater Instructors is a non-profit 501 (c) (6) association of scuba instructors. It is a recreational dive certification and membership organization established to provide international diver standards and education programs. The agency was founded in 1960 by Albert Tillman and Neal Hess. NAUI is headquartered in Tampa, Florida, US) with dive and member instructors, resorts, stores, service and training centers, located in Japan, South Africa, the Middle East, Europe, Brazil and the Pacific Rim.

Diver certification Certification as competent to dive to a specified standard

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.

Open Water Diver An entry-level autonomous diver certification for recreational scuba diving

Open Water Diver (OWD) is an entry-level autonomous diver certification for recreational scuba diving. Although different agencies use different names, similar entry-level courses are offered by all recreational diving agencies and consist of a combination of knowledge development (theory), confined water dives and open water dives (experience) suitable to allow the diver to dive on open circuit scuba, in open water to a limited depth and in conditions similar to those in which the diver has been trained or later gained appropriate experience, to an acceptable level of safety.

Diver training Processes by which people develop the skills and knowledge to dive safely underwater

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.

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.
