California has one of the strictest programs for the registration and use of pesticides in the United States. The California Department of Pesticide Regulation (CDPR), a department of the California Environmental Protection Agency (Cal/EPA) has the primary responsibility for regulating all aspects of pesticide sales and use to protect the public health and the environment. They are also responsible for enforcement of California pesticide laws. This includes the requirement of training and certification of pesticide applicators. For public health pesticides, CDPR has delegated training and certification to the California Department of Public Health (CDPH), and the Vector-borne Disease Section (VBDS) of CDPH conducts periodic testing of new applicants for licenses for pesticide application as well as existing license holders.
Training materials for pesticide certification and re-certification are available on the VBDS website (VBDS Training) and also under this section. Included here are pesticide training manuals and other study materials, including practice quizzes in various forms.
