Coursework

  • Biology with labrequiredextra here

    6 credits

    Two semesters the baseline does not carry: "General Biology I, 3" and "General Biology II, 3," each "the first part" and "the second part of an introductory level biology course for science majors. Courses for non-science majors are not acceptable." Unusually, the "Laboratory component not required" for either.

  • General chemistry with labrequireddiffers

    6 credits · lab

    Most PA programmes ask for 2 semesters · 8 credits · lab.

    Both semesters, three credits each: "General Chemistry I" and "General Chemistry II," the introductory sequence for science majors, with "Laboratory component required" on both. "Courses for non-science majors are not acceptable."

  • Biochemistryrequired

    1 semester · 3 credits

    Either course satisfies it: "Choose any introductory organic chemistry or biochemistry course. Courses for science and health professions majors preferred. Laboratory component not required."

  • English or writing-intensivenot required here

    No English or composition credits appear on the prerequisite course list.

  • Statisticsrequireddiffers

    2 credits

    Most PA programmes ask for 1 semester · 3 credits.

    Only two semester credit hours, and the department is unusually open about the source: "Choose any statistics course in any discipline." The course "should include topics such as statistics terms, analytical statistics, measurement of the mean and variance, null hypothesis, p-values, confidence intervals, and probability." Calculus does not substitute: asked whether the program accepts calculus for the statistics prerequisite, NAU answers "No, it does not."

  • Psychologynot required here

    Psychology is not on NAU's prerequisite course list, which runs biology, microbiology, anatomy and physiology, twelve credits of additional sciences, two semesters of general chemistry, organic chemistry or biochemistry, and statistics.

  • Anatomy and physiologyrequireddiffers

    6 credits · lab

    Most PA programmes ask for 2 semesters · 8 credits · lab.

    Six semester credit hours rather than eight, taken either as "Anatomy & Physiology I and Anatomy & Physiology II" or as separate anatomy and physiology courses. "Human focused is preferred. A&P courses for non-science majors are not acceptable. Laboratory component required for both A&P I and A&P II." If taken separately, "Anatomy must cover all body systems. Physiology must cover all body systems," and both need labs.

  • Microbiologyrequireddiffers

    3 credits · lab

    Most PA programmes ask for 1 semester · 4 credits · lab.

    "Choose an introductory microbiology course. Courses for non-science majors are not acceptable. Laboratory component required." Three semester credit hours.

  • Medical terminologynot required here

    Not among the published prerequisite courses.

  • Additional science creditsrequiredextra here

    4 semesters · 12 credits

    NAU's largest requirement and the one most easily missed: a twelve credit Additional Sciences block. Recorded on the science electives key rather than advanced biology, because it is broader than biology: "CASPA course subjects that contribute to the CASPA Science GPA are accepted as Additional Sciences for this requirement. Science courses intended for science majors and/or upper division coursework is more competitive for admissions purposes. Laboratory components are not required for these courses." These twelve credits must be separate courses from the named prerequisites, since double dipping is not allowed, and a combined lecture plus lab course cannot have its extra credit split off toward the twelve unless the lab was a separate registration.

Experience hours

  • Patient care experiencenot required here

    NAU asks for healthcare experience, not patient care specifically: "Does the program require direct patient care experience? Direct patient care experience is not required; however, it is highly recommended." The 500 hour minimum is recorded on the healthcare experience line instead, and hands-on roles count toward it fully.

  • Healthcare experiencerequireddiffers

    500+ hours

    Most PA programmes ask for 500+ hours and list it as recommended.

    This is the hours line that matters at NAU, and it is healthcare experience rather than patient care: "Complete a minimum of 500 hours of health care experience by September 1. Both volunteer and paid experiences are acceptable," and "The program does not prefer paid over volunteer health care experience." The hours must already be in hand: "Applicants should have already completed the minimum of 500 hours prior to submitting their application. Projected healthcare experience hours are not accepted," and the program does not recalculate hours later in the cycle. Accepted roles run wide, from medical assistant, EMT, CNA, paramedic, RN and LPN through phlebotomist, athletic trainer, radiology technician and registered dietician, and NAU also counts medical scribe, research technician, lab based researcher, volunteering at marathons and blood donor clinics, and "other non-medical work in waiting room or other medical setting." Clinical hours earned as a student in a previous degree count if the CASPA description makes the training role clear.

  • PA shadowingnot required here

    "No, PA shadowing is not required for admission; however, shadowing a PA can provide some valuable insights about the profession. It can also be counted as health care experience." Shadowing hours earn no separate credit here: "Applicants with PA shadowing and/or letters from PAs are not given any advantage in the admissions process."

Letters

  • Science faculty letterrecommendeddiffers

    1 letter

    Most PA programmes publish no minimum.

    NAU names "professors" among its preferred writers but specifies no discipline and requires no faculty letter.

  • PA letterrecommendeddiffers

    1 letter

    Most PA programmes publish no minimum.

    Three letters of reference are required but no writer is prescribed: "Who can write letters of reference for me? Anyone the applicant chooses. The program prefers letters from health care professionals applicants have shadowed or worked with, employers/supervisors and professors. Letters from friends and family are discouraged." A PA letter earns nothing extra: "Applicants with PA shadowing and/or letters from PAs are not given any advantage in the admissions process." All three must be complete in CASPA by September 1 or the application cannot be considered further, and letters sent outside CASPA cannot be used.

  • Supervisor letterrecommendeddiffers

    1 letter

    Most PA programmes publish no minimum.

    Preferred rather than required. Employers and supervisors are among the three writer types NAU says it prefers for the three required letters, alongside health care professionals you have shadowed or worked with, and professors.

Also on the school’s page

NAU's admission requirements page carries the detail in two linked documents, the Minimum Requirements for Admission sheet and the Prerequisite Course List at https://in.nau.edu/wp-content/uploads/sites/309/NAU-MPAS-Prerequisite-Course-List-3.26.2024.pdf, with the program FAQ at https://in.nau.edu/physician-assistant/faqs/ filling in policy. On tests: "Does the program require the GRE? No. The department discontinued the GRE requirement on March 17, 2020," and no PA-CAT is mentioned. Minimums are stated as minimums: a bachelor's or higher degree from a U.S. regionally accredited institution, "Overall and science course GPA of 3.0 or higher (CASPA calculation)," 500 hours of health care experience, and three letters. Applicants must be U.S. citizens or permanent residents. Timing is unusually strict: both the CASPA and the NAU applications are due September 1, CASPA must verify by October 1, and "All prerequisite courses must be completed, graded, and reported to CASPA at the time of application." Recency works differently here from most programs: prerequisites themselves never expire, but a standing requirement is "A minimum of nine (9) credits of science courses completed in the last five (5) years," and "The 9 credits do NOT have to be sciences listed in the prerequisites." Grades are more forgiving than most, with "A letter grade (A, B, C or D) or numerical grade" acceptable and F, W, WF and DF not accepted, though "the higher the grade, the more competitive the applicant"; pass or credit grades are accepted by permission only. Two rules trip people up: "'Double-dipping' is not allowed. Double-dipping is defined as using a prerequisite course to satisfy more than one prerequisite requirement," and "The program does not waive any prerequisite requirements." Courses may be taken at any U.S. regionally accredited school including online programs. The program gives preference to "applicants who indicate a high potential for remaining in the state of Arizona to work following graduation" and to first generation college students, economically and educationally disadvantaged applicants, underrepresented populations, military veterans, and applicants from rural backgrounds.
