The First Annual Gulf Coast Measurement Short Course (GCMSC) was held in Houston, Texas in October, 1966, under the sponsorship of the Gulf Coast Gas Measurement Society and the University of Houston. Following the 1973 Short Course, the relationship with the University of Houston was terminated and the Short Course became affiliated with Texas A&I University. In 1974, the Executive Committee voted to accept participation by other affiliated organizations to enhance the growth of the Short Course. The Corpus Christi Area Measurement Society became affiliated in 1975, the Victoria Area Measurement Society followed in 1976, the Texas Gas Association in 1978, and the Northeast Texas Measurement Society in 1981. In 1989, several changes were made. The Victoria Area Measurement Society was discontinued as an affiliate and the Permian Basin Measurement Society was added as a new affiliate to the Short Course. One affiliate had a name change. The Northeast Texas Measurement Society is now known as the North Texas Measurement Association.

In 1991, the Board of Directors voted to change the name of our school from the Gulf Coast Measurement Short Course to the American School of Gas Measurement Technology (ASGMT). With a vision for international participation, continued growth, and a broader industry recognition, the Board of Directors has set a course for future expansion by adopting a more comprehensive school format while expanding upon the tradition and quality of the “Short Course”. The School is planned and operated by the General Committee which is comprised of approximately 59 members from various operating and manufacturing companies in the natural gas industry.

In 1994, while maintaining its co-sponsorship, Texas A&I University became Texas A&M University – Kingsville.
