The correct comparison of the educational requirements for doctors and physician assistants is:
Physician assistants require a lower degree because they act under the close supervision of a doctor.
Physician assistants (PAs) typically complete a master's degree program after earning a bachelor's degree, while physicians (MDs or DOs) are required to complete medical school, which can take an additional four years, followed by residency training that lasts from three to seven years or more, depending on their specialty. PAs do work under the supervision of a physician, which also contributes to their different scope of practice and educational requirements.
