YMCA SCUBA Program
YMCA SCUBA Program (also known as Y-SCUBA) was an underwater diving training program operated by YMCA of the USA from 1959 to 2008. It was the first nationally organised underwater diving instruction program offered in the United States of America. A program with a similar content is now delivered by Scuba Educators International, an organisation founded by a group of former senior YMCA SCUBA instructors in 2008. Origins. In 1954, YMCA of the US and other interested parties under the auspices of the Council for National Cooperation in Aquatics commenced a study to look at the  safety aspects of underwater diving. Findings of the study were outlined with the view of creating a course of training sufficient to produce ‘capable performance in those who elect to participate in… recreational (diving) activity’. A trial course was run during the late 1954 and early 1955 by YMCA of the USA using this outline. The material used in the course was then published in "The Science of Skin and SCUBA Diving" (or "The New Science of Skin and SCUBA Diving" as some sources suggest) during 1957. YMCA of the USA then developed its own program of underwater diving instruction  for delivery as part of its existing aquatics program. It certified its first snorkelling and scuba diving instructors in August 1959, thereby becoming the first nationally organized underwater diving training program offered in the US. Winding up. In July 2008, YMCA of the USA announced that the scuba program would cease on December 31, 2008 and that it would continue to replace lost certificate cards for training conducted from 1984 to 2008. In 2008, a group of former YMCA SCUBA instructors created a new organisation called Scuba Educators International (SEI) for the purpose of continuing YMCA SCUBA diver training program  under a new banner. Recognition. In 1980, YMCA SCUBA joined CMAS, thereby gaining access to CMAS International Diver Training Certificates for its divers and instructors.
