Certified Seed Sampler Training Registration


California Crop Improvement Association (CCIA) executes a Seed Sampler Certification Program under AASCO’s (Association of American Seed Control Officials) oversight. The objective of this Program is to ensure that certified seed samplers use methods and equipment that are approved by AOSA (Association of Official Seed Analysts).  Seed sampler training should lead to uniformity in sampling of all certified seed that is produced and used in or derived from our state. More importantly, it should also lead to accurate seed test results and labels that better reflect the quality of seed in warehouses being offered for sale and/or shipment. Therefore, CCIA requires that all seed samples sent to the seed laboratories for certification purposes be sampled by certified samplers. This workshop is intended for the Agricultural Commissioner and seed warehouse personnel that are or will be sampling seed according to the AOSA rules. 


The workshop content will include:

  • Industry scope and role of seed sampling
  • Ethics of seed samplers; Professionalism and safety
  • Sampling equipment
  • Sampling seed in bags
  • Sampling seed in mini-bulk containers
  • Sampling seed in bulk containers
  • Special sampling situations
  • Samples, their division and nomenclature
  • Quality assurance.

The workshop will also include a hands-on practical component. A content examination will be administered. Spanish speaking candidates are especially encouraged to attend. Spanish language translation facilities will be available. And the Spanish version of the AASCO Handbook on Seed Sampling and content examination will also be available. The workshop will start at 8:00 AM and end at 5:00 PM. Qualifying candidates will be certified by AASCO and CCIA and the certification will be valid for 3 years.


Please note that the registration fee of $50 will include the cost of the AASCO Handbook on Seed Sampling and Lunch. Those who were certified in 2017 and 2018 need not register. If you already have the Handbook please bring it to the workshop for verification as it is AASCO’s requirement that all AASCO Certified Seed Samplers must have a copy. Those wishing to attend may visit the CCIA Seed Sampler Certification Program web page for more information about seed sampling. You will need a small calculator, a pen and a notebook or pad for notes.
