The correct comparison of the educational requirements for doctors and for physician assistants is:
Physician assistants require a lower degree because they act under the close supervision of a doctor.
Physician assistants typically complete a master's degree program after obtaining a bachelor's degree, while doctors (physicians) must complete a medical degree (usually after earning a bachelor's degree) and typically undergo residency training, which can take several additional years. Therefore, physician assistants' educational requirements are generally lower compared to those of doctors.
