Private Applicator Certificate Exam and Review Sessions Registrations

Effective January 1, 2024, individuals who are currently certified as Private Applicators will need to take and pass the revised Initial PAC Exam to demonstrate competency with the revised Private Applicator standards in 40 CFR Part 171.

Our office will be hosting multiple review sessions to help prepare for the revised PAC exam, followed by the exam sessions. Please make sure to register on time as these sessions will have limited seats. You can register here or by calling our office at (209) 525-4730.

  • PAC for the last names beginning with 'R-Z' expire on December 31,2023. These individuals still have the option to renew via CE hours, if they renew prior to January 2024.
  • PAC for the last names beginning with 'A-Q' must take and pass the revised examination for re-certification.
  • Beginning January 1, 2024, all PAC holders regardless of expiration date must also possess a separate Burrowing Vertebrate Pest Fumigation if needed.
  • Stanislaus County is hosting review sessions to help you prepare for this newly revised PAC Exam.
