Which two of the following are required for licensed PCOs?

The requirement for licensed Pest Control Operators (PCOs) to take and pass an exam administered by the state is fundamental to ensure they possess the necessary knowledge and skills to operate safely and effectively in their field. This examination typically covers various critical topics, including understanding pest biology, pesticide application methods, safety protocols, and applicable state regulations. This knowledge is essential not only for the efficacy of pest control measures but also for the health and safety of the public and the environment.

Maintaining a high standard of professionalism through a testing requirement helps regulate the industry, ensuring that only qualified individuals are allowed to perform pest control tasks which can include the use of potentially hazardous chemicals. State-administered exams serve as a benchmark for competency and are vital for licensing processes, thus ensuring that PCOs are equipped to manage their responsibilities responsibly.

The other options suggest prerequisites or ongoing educational requirements that do not universally apply as strictly as passing the state-administered exam. While some states may have apprenticeship or continuing education mandates, these are not standard requirements for every licensed PCO.
