ICN Professional Certification 

The ICN Pro Program was created to uphold and promote the standards of professionalism and excellence within our industry.  By focusing on individual certification, the program encourages self-improvement and continual learning.  The program was initially developed with a focus on the garden center and retail segment of our industry but is open to all horticultural professionals looking to expand their skills and knowledge.

There are currently two types of certification available - Woody and Perennial. Professionals may become certified in one or both types. Skills and knowledge needed to serve the public will be proven by exam, which will be offered at various times and places throughout the state. The written exam is based upon information found and the study manual available through the IGIA office. The exam also covers plant, insect and disease identification, and basic landscape design.

Successful candidates will be awarded an ICN Pro certificate, patch and the right to advertise ICN Pro status on letterhead, business cards, clothing, etc. Certification is for individuals, not firms, and the ICNPro title may be promoted only in relation to individuals.


Enrollment in the ICN Pro Program is voluntary. To become certified, an individual must:

  1. Be the owner or officer of a nursery firm; or currently be employed by a nursery firm for a total of 4,000 hours; or currently be employed by a nursery firm for a total of 2,000 hours and have successfully completed 2 full years of classroom study in a recognized college-level horticultural program.
  2. Successfully complete the ICN Pro examination.
