I am in a three year PA program within a medical school. We take a number of our classes with the medical students and have the same exams and same educational expectations. Our clinical medicine classes are taught by the medical school professors who say they teach them no differently. Our physical examination and OSCE courses are the same. The pharmacology classes (three semesters long, 4 credits each) are taught by PharmDs who are tenured in their departments are engaged in research. We are trained in general primary care, to be active in CME, and never let our knowledge become stale. As an example we recently had several lectures and a lengthy exam in the JNC 8 guidelines in order to ensure that our knowledge is up to date. We are also required to do a capstone project on original research. PAs complete a full year (50 weeks, 2000 hours) of clerkships which last for five weeks. PAs are also able to do 1-1.5 year long post-graduate residencies/fellowships which often take place alongside the newly graduated MDs. Clearly MD/DOs have more years of training, both didactic and clinical. PAs do not dispute or minimize the importance of this.
PAs required to retake our licensing exam (called the PANRE) every ten years and it's a brand new test every ten years which reflects the latest in medical education and medical knowledge. This ensures we are practicing with the latest and greatest which medicine has to offer. I'm trying to paint the picture that there is far more in common between PA and MD education than there are differences. Certainly MDs are the king-of-the-castle and PAs have no interest in changing the physician-lead dynamic. We always want the MD (or DO) to be in collaboration with us and to be available for the particularly complicated patients. We do wish that our education and experience be valued for the high quality and intensive nature that it is and for it not to be belittled.
I would be very scared if myself or a family member were to come under the care of an NP, who have more education on "nursing philosophy" and don't know what they don't know.
