The Society of Commercial Seed Technologists is a organization comprised of commercial, independent and government seed technologists. Formed in 1922, the SCST functioned as a liaison between the Association of Official Seed Analysts (AOSA) and the American Seed Trade Association (ASTA). The SCST has developed over the years into a progressive organization that trains and provides accreditation of technologists, researches and develops rule changes, publishes training and education materials, and serves as an important resource to the seed industry.
