It is the textbook for scholars and students alike to reference and use both in the classroom and in general practice. The scope is broad and encompasses all of the literature that has shaped the PA profession and is also provides in-depth information on areas of scholarly activity such as PA education, PA legislation, and the economics of PA practice.
