Advanced Open Water Diver (AOWD) is a scuba diving certification level provided by several diver training agencies, such as Professional Association of Diving Instructors (PADI), and Scuba Schools International (SSI). The equivalent course offered by National Association of Underwater Instructors (NAUI) is the Advanced Scuba Diver. The certification level is roughly equivalent to the CMAS * Diver qualification and the British Sub-Aqua Club (BSAC) Ocean Diver qualification, although some differences occur. For example, BSAC Ocean Divers are trained in the use of Nitrox and basic rescue skills for recreational diving.
The SSI Advanced Open Water program is different from most other organizations, as they require not only training but they also require diving experience. To be certified as a SSI AOWD one needs to have completed four specialty courses and minimum of 24 logged dives. In the absence of a logged dives requirement, it is possible to become certified as AOW with some other agencies while having less than 10 lifetime dives.
Scuba Diving International (SDI) offers an Advanced Adventure Diver course similar to the Advanced Open Water Diver Course offered by the Agencies noted herein.

Famous quotes containing the words advanced, open and/or water:
“America was indebted to immigration for her settlement and prosperity. That part of America which had encouraged them most had advanced most rapidly in population, agriculture and the arts.”
—James Madison (1751–1836)
“...there are important considerations in the world beyond plain sewing and teaching dull little boys the alphabet. Any woman who has brains and willing hands finds twenty remunerative occupations open to her where formerly she would have found merely the inevitable two—plain sewing, or the dull little boys. All she had to do is to make her choice and then buckle on her armor of perseverance, while the world applauds.”
—Clara (Marquise)
“Ice is an interesting subject for contemplation. They told me that they had some in the ice-houses at Fresh Pond five years old which was as good as ever. Why is it that a bucket of water soon becomes putrid, but frozen remains sweet forever? It is commonly said that this is the difference between the affections and the intellect.”
—Henry David Thoreau (1817–1862)
