Additional information about CCA certification:

The Certified Crop Adviser (CCA) and Certified Professional Agronomist (CPAg) programs of the American Society of Agronomy are the benchmarks of professionalism.  The CCA certification was established in 1992 to provide a benchmark for practicing agronomy professionals in the United States and Canada.

Certification is the standard by which professionals are judged. The purpose of a certification program is to protect the public and the profession. It is a voluntary professional enhancement to a person's career credentials. Farmers and employers prefer to work with Certified Crop Advisers (CCA) because CCAs have demonstrated they have the commitment, education, expertise, and experience to make a difference in a client's business.

Steps to Certification:

  • Pass two exams – local and international. Registration information can be found at:
  • Document education and experience.
  • Sign and agree to uphold CCA code of ethics.

Once certified: 

  • Earn 40 hours of continuing education every two years and pay an annual renewal fee (fees are subject to change).

Next CCA Exam Date:  February 7, 2020 -- Registration period October 7 - December 13, 2019
