A plain-English walkthrough of getting certified in California — which DPR credential you need, the Laws, Regulations, and Basic Principles exam plus category exams, what it costs, and how to study and pass. Agricultural and landscape pesticide certification is run by the Department of Pesticide Regulation (DPR); structural pest control (Branch 1-3 work) is licensed separately by the Structural Pest Control Board.
Every QAL and QAC candidate passes the Laws, Regulations, and Basic Principles exam — the California version of the CORE foundation — plus at least one category exam (A through M) for the work they do. Exams are computer-based at testing centers statewide; you apply by mail to DPR, may request up to four exams per application, and can apply once per month. You must be at least 18, and QAL/QAC applicants document qualifying education or experience. Private applicators test through their county agricultural commissioner instead.
DPR raised fees in August 2024: exams are now $115 each and the QAC application fee is $90; a new QAL application is $180 and the QAL renewal is $270 per two-year cycle — check the current DPR fee schedule before mailing anything. Credentials run on a two-year cycle (last names A-L expire December 31 of even years, M-Z odd years) and renew with 20 hours of DPR-approved continuing education, at least 4 of them in laws and regulations. Private applicator certification through the county is far cheaper, with 6 CE hours to renew. Structural work is licensed by the separate Structural Pest Control Board.
California credentials run on a two-year cycle keyed to your last name — A through L expire December 31 of even years, M through Z in odd years. QAL and QAC holders renew with 20 hours of approved continuing education earned inside the cycle, at least 4 of them in laws and regulations (a few single-category holders, such as H-only, owe fewer). Hours must be complete by December 31 of your expiration year; renewal stays open up to a year late with a late fee, but missing the CE means retesting. Nothing carries over. Confirm current hour requirements with DPR before your cycle ends.
