Prerequisite Courses for Physician's Assistant

For most Physician Assistant programs there are a core set of required courses.  However, many programs have additional courses that they require and these vary from one program to another.  If you are interested in a career as a physician assistant, you need to research the individual schools that are of interest to you to be sure that you are taking all of the courses they require. 

Core Prerequisite Courses (required by most programs)

  • Two semesters of General Biology with labs: BIO 110 and BIO 111
  • Two semesters of General Chemistry with labs: CHEM 111 and CHEM 112
  • One semester of Anatomy with a lab: BIO 341
  • One semester of Physiology with lab: BIO 350 - some programs will accept BIO 245 and BIO 246 instead of BIO 341 and BIO 350.  Please be sure to check with each individual school for details.
  • Two semesters of Psychology - some programs will accept any two courses with a PSY prefix, but others explicitly state that they require Developmental Psychology (PSY 230) and Abnormal Psychology (PSY 255).  If the program you are interested in requires Abnormal Psychology, you will also need to take PSY 120 (Principles of Psychology) which is a prerequisite for PSY 255.
  • One semester of Statistics: STAT 150 - many schools will not accept business statistics.
  • One semester of college math - many programs will accept College Algebra: MAT 124
