AOSCA,
the leader in the development of crop standards and variety review for certified seed since 1919
AOSCA member agencies certify around 3.2 million acres of seed and vegetatively propagated crops annually.
For quality you can trust, choose Certified seed inspected by one of AOSCA’s members agencies.

The Association of Official Seed Certifying Agencies is dedicated to assisting clients in the production, identification, distribution and promotion of certified classes of seed and other crop propagation materials.

The Association of Official Seed Certifying Agencies (AOSCA)

is a non-profit organization founded in 1919 (formally known as the International Crop Improvement Association) in an effort to establish credible standards for the production of high-quality seed. Today, AOSCA has member agencies across the U.S. as well as seven member countries including Canada, Argentina, Brazil, Australia, New Zealand, and South Africa.

There is only one certification agency in each state; generally a Crop Improvement Association, Seed Growers Association, Department of Agriculture, or within an Agricultural College. Each member agency adheres to the AOSCA minimum standards but has the flexibility to make standards more stringent if necessary for the production in their own state. All AOSCA standards abide by the Federal Seed Act requirements for certified seed.

Today, AOSCA member agencies certify around 3.2 million acres of seed and vegetatively propagated crops annually.

In addition to establishing crop standards, AOSCA also hosts the National Variety Review Board (NVRB) for Alfalfa/Legumes, Grass, Hemp, Small Grains, and Sunflowers. The NVRB establishes eligibility requirements for varieties entering certification programs, focusing on genetic purity, novelty, and sufficient data to support claims made by plant breeders for new varieties. These review boards are comprised of plant breeders, AOSCA members, seed industry professionals, USDA-AMS, USDA-PVP, and others. The goal of each NVRB committee is to offer a non-biased peer review process. The review and recommendation for certification of a variety is not merit based. The market, rather than AOSCA, will ultimately determine if the variety is successful.

AOSCA is led by Chief Executive Officer, Dr. Sarah Wilbanks along with a Board of Directors consisting of two members from each U.S. Region, and two Global representatives.  For additional detailed information regarding AOSCA, use the link at the top right of this pag
