The job duties of a part-time physician assistant (part-time PA) focus on providing primary care to patients and offering support to licensed physicians. As a part-time physician assistant, you work less than 40 hours per week on average. During your shift, you handle responsibilities like examining and diagnosing patients, making assessments, providing treatment, and ordering tests. Typically, a physician assistant works under the supervision of a doctor. You can perform specialized tasks, such as assisting with surgery or procedures. While there are limits to what you are allowed to do, PAs have some independence in their job.
