California law requires all county employees working in the capacity of Weights and Measures Inspector to possess licenses demonstrating job proficiency. While the CDFA is tasked with overseeing the testing and licensing of potential candidates, each county is responsible for hiring and determining the qualifications of its own employees. To be hired, candidates must qualify for the licenses of eligibility exams and meet all requirements of the hiring county. Counties may require additional experience or education beyond that of the licensing exam requirements.

Expiring licenses may be renewed, at the request of the license holder, without further examination if the holder is employed in any county agricultural or weights and measures position, with the California Department of Food and Agriculture, or with the California Department of Pesticide Regulation. A holder of a license of eligibility who is not employed in one of the above capacities, but who otherwise meets the minimum license qualifications, may apply to renew the license prior to its expiration upon passing a requalifying exam.
