Produce Professional Certificate

Pathways  |  FAQs

The Produce Professional Certificate program provides customized curriculum via in-person workshops and online video modules. Participants must complete 120 course points across a 4 year period to gain certification. One hour of instruction is equivalent to 1 course point. Points are earned through completion of in-person workshops or online modules where a passing score of 80% or higher is achieved for the corresponding quiz. We offer a 2 year retroactive option for participants who attended a Postharvest Technology Center workshop and would like credit for the course under the Certificate program.

The Certificate program is maintained in an online learning management system (LMS) providing participants access to course resources and quizzes at their convenience. Course resources include video lectures and PowerPoint handouts, which may serve as a reference for completion of the course quiz. Quizzes vary length and are dependent upon the length of the course. Quizzes may be taken multiple times until a passing grade is earned.

Earning a Produce Professional Certificate from the UC Davis Postharvest Technology Center equips individuals with a set of tools representing all aspects of postharvest handling. Upon completion of the program, participants will have demonstrated knowledge in produce safety, harvesting systems, cooling, packaging, transportation, quality, modified atmospheres and marketing fresh produce in addition to being up-to-speed on current research in these areas.
