Scuba Educators International (SEI) (also known as SEI Diving) is a non-for-profit underwater diving training organisation established in the United States during 2008 to continue the underwater diving training program known as the YMCA SCUBA Program which ceased operation in 2008.


SEI was founded in 2008 by a group of former senior YMCA SCUBA instructors following the announcement of the closure of the YMCA Scuba Program by the YMCA of the USA with the intention of continuing the YMCA Scuba Program under a new banner.[1] The new agency was conceived as being a non-for-profit organisation that would operate world-wide and in complete independence of the YMCA of the US, “but will continue to share philosophies and dedication to the highest quality education in the (diving) industry”.[2]


During 2010, SEI entered in an agreement with the Underwater Society of America (USOA) to issue CMAS International Diver Training Certificates.[3] SEI is a member of the Diving Equipment and Marketing Association (DEMA) with its CEO, Tom Leaird, serving on the DEMA Board of Directors.[4]


The SEI Qualification System was structured as of July 2014.[5]
