Exploring the Physician Assistant Profession
Exploring the Physician Assistant (PA) Profession
Physician assistants provide medical care in settings ranging from primary care and emergency medicine to surgery and specialty practice. Learn about the profession, PA school preparation, patient care experience, and the application process.
Start with the profession, then build your plan
Use this page for an introduction to the PA profession and the major parts of preparing for PA school. The HPA Physician Assistant Handbook provides more detailed guidance and can be revisited throughout your undergraduate years and application cycle.
Physician assistants are licensed medical professionals who evaluate patients, diagnose illness, develop treatment plans, prescribe medications, perform procedures, and provide preventive care. They work with physicians and other healthcare professionals as part of the patient care team.
PAs practice throughout medicine, including primary care, emergency medicine, surgery, pediatrics, psychiatry, orthopedics, dermatology, cardiology, oncology, and many other specialties.
PA education prepares graduates as medical generalists. This broad training allows PAs to move into different specialties during their careers. A PA entering a new specialty may need additional training or orientation, but a second professional degree is generally not required.
The PA profession may be a good fit for students who:
- Enjoy direct patient care and clinical problem solving.
- Are interested in diagnosing and treating medical conditions.
- Value collaboration with other healthcare professionals.
- Want the ability to work in different areas of medicine over the course of a career.
- Are comfortable with ongoing learning as medicine and clinical practice change.
Training and certification
Most students enter PA school after completing a bachelor’s degree, required prerequisite coursework, and the healthcare or patient care experience expected by the programs to which they are applying.
Entry-level PA programs are graduate programs accredited by the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA). After graduating from an accredited program, graduates must pass the Physician Assistant National Certifying Examination (PANCE) and meet the requirements for licensure in the state where they plan to practice.
Residency is not required before a PA begins practice. Optional postgraduate residencies and fellowships are available in some clinical areas.

Most PA programs do not require a particular undergraduate major. Students may choose a major that fits their academic interests while completing the prerequisite coursework required by the programs they plan to apply to.
PA prerequisites vary significantly by program. Schools may differ in required courses, laboratory requirements, minimum grades, prerequisite GPA expectations, and how recently coursework must have been completed. Policies for AP credit, online courses, community college coursework, and repeated courses also differ.
Common prerequisite areas include:
- Biology with laboratory
- General Chemistry with laboratory
- Human Anatomy & Physiology
- Microbiology
- Statistics
- English or writing-intensive coursework
- Psychology, human development, or other behavioral science coursework
- Organic Chemistry, Biochemistry, Genetics, Medical Terminology, or other courses required by individual programs
The CASPA Program Directory and individual program admissions pages are useful for comparing current prerequisite requirements. Research programs early enough to adjust your academic plan if schools you are considering require coursework outside your major.
Academic performance
Programs may review cumulative GPA, science GPA, prerequisite GPA, academic trends, and performance in advanced science coursework. Published minimum GPAs indicate whether an applicant meets a program’s basic eligibility requirements. The academic profile of admitted students may be higher.
Course planning should support steady academic progress and leave enough time for your other responsibilities. Work with your faculty advisor on sequencing and degree requirements, especially when prerequisites fall outside your major.
Students with academic concerns should meet with HPA before the application year. Additional coursework can be useful in some situations, but the appropriate plan depends on the student’s academic record and the programs under consideration.
Admissions & Program Resources
Clinical experience is a major part of PA school preparation. Many programs expect applicants to have spent substantial time working with patients before entering professional school.
Patient Care Experience (PCE)
Patient care experience generally involves direct responsibility for patient care. Depending on the role, this may include taking vital signs, assisting with activities of daily living, administering treatments, performing clinical procedures, responding to emergencies, or providing other hands-on care.
Common roles include EMT, CNA, patient care technician, medical assistant, nurse, paramedic, respiratory therapist, athletic trainer, surgical technologist, and other clinical positions. Programs decide for themselves which roles qualify as PCE, so the same job may be classified differently by different schools.
Healthcare Experience (HCE)
Healthcare experience takes place in a healthcare environment but may involve less direct responsibility for patient care. Examples may include hospital volunteering, patient transport, pharmacy work, medical reception, laboratory work, or administrative positions in healthcare settings.
HCE can provide useful exposure to healthcare, but applicants should check whether their intended programs require a separate amount of direct patient care experience.
Shadowing
PA shadowing can help you see how the profession functions in practice. Pay attention to the PA’s scope of responsibility, interactions with physicians and other clinicians, approach to patient education, and role within the care team.
Other experiences
Service, employment, leadership, research, athletics, teaching, and campus involvement can all contribute to your development. Choose activities that are meaningful to you and stay involved long enough to take on responsibility and learn from the experience.
Related HPA Resources
Standardized testing requirements vary considerably among PA programs. Some require an admissions exam, while many do not. Review the requirements for every program on your school list before registering for a test.
Graduate Record Examination (GRE)
Some PA programs require, recommend, or accept the GRE. The exam assesses verbal reasoning, quantitative reasoning, and analytical writing. If the GRE is required for programs on your list, allow enough time for preparation, score reporting, and a possible retake before your earliest deadline.
Physician Assistant College Admission Test (PA-CAT)
The PA-CAT is an admissions exam developed specifically for PA programs. It focuses on prerequisite science knowledge and includes anatomy, physiology, biology, biochemistry, chemistry, microbiology, behavioral sciences, genetics, and statistics.
Only some programs require or use the PA-CAT. Students should take it only when it is relevant to schools they are considering and should review the official exam blueprint and preparation materials before choosing a test date.
Casper
Casper is an online situational judgment test used by some PA programs. It presents interpersonal and professional scenarios and assesses how applicants respond and explain their reasoning. Preparation should focus on understanding the format and practicing clear, thoughtful responses rather than studying science content.
Testing policies and deadlines can change between application cycles. Confirm current requirements through each program’s admissions website and CASPA listing before scheduling an exam.
PA school preparation usually develops over several years. Your timeline will depend on prerequisite coursework, clinical experience, academic preparation, and when you feel ready to apply.
Earlier in college
- Begin prerequisite coursework and work with your faculty advisor on course sequencing.
- Learn about the PA profession through shadowing and conversations with practicing PAs.
- Research patient care roles, including any training or certifications required to begin working.
- Begin keeping records of experiences and hours.
As you approach the application cycle
- Review your prerequisite completion and remaining coursework.
- Continue building patient care experience.
- Develop a realistic school list and compare admissions requirements.
- Identify recommendation writers who know your work well.
- Begin preparing CASPA materials and written responses.
Gap years
Many PA applicants take one or more gap years before beginning professional school. This can provide time to accumulate patient care hours, finish prerequisites, strengthen an academic record, work full time in healthcare, or become more certain about the profession.
Academic enhancement
Some students benefit from additional undergraduate science coursework, a post-baccalaureate program, or graduate study before applying. The value of additional coursework depends on the student’s academic history and should be considered individually.
Most accredited PA programs participate in the Centralized Application Service for Physician Assistants (CASPA), which is administered by the Physician Assistant Education Association. Applicants can use one CASPA application to apply to multiple participating programs.
Schools set their own admissions policies. Prerequisites, minimum GPAs, patient care expectations, testing requirements, supplemental questions, deadlines, and interview processes can all differ.
Choosing programs
Start with programs where you meet the prerequisites and experience requirements. Then review the curriculum, clinical rotations, cost, location, accreditation status, PANCE outcomes, program mission, and student support.
The ARC-PA maintains the official list of accredited entry-level PA programs. Check a program’s current accreditation status as part of your school research.
The CASPA application
CASPA collects academic history, coursework, transcripts, evaluations, experiences, test information when applicable, and program-specific materials. CASPA verifies entered coursework against official transcripts and calculates standardized GPA information for participating programs.
Review every section carefully before submitting. CASPA limits the changes that can be made after submission, and verification takes time.
Personal statement and experiences
Your personal statement should explain why you are pursuing the PA profession and how your experiences informed that decision. The experiences section gives programs more detail about your patient care work, healthcare exposure, employment, service, shadowing, leadership, and other activities.
Letters of recommendation
Letter requirements are set by individual programs. Depending on the school, applicants may need evaluations from a PA, healthcare supervisor, faculty member, employer, or another professional who knows their work well.
Villanova HPA offers a letter packet process for eligible applicants. Review the current HPA Letter Packet Process page for eligibility, forms, and cycle-specific deadlines.
Interviews
PA programs use several interview formats, including individual interviews, panels, group interviews, and Multiple Mini Interviews. Programs may conduct interviews in person or virtually.
Prepare to discuss your understanding of the profession, patient care experiences, reasons for applying, and what you learned from the experiences included in your application. Know the program well enough to explain why you are interested in its particular training environment.
Application timing
The CASPA cycle opens in the spring. Program deadlines vary, and some programs use rolling admissions. Review each school’s deadline type in CASPA so you know whether the application must be submitted, complete, or verified by the stated date.
Submitting early can matter for rolling programs, but give yourself enough time to submit accurate and polished materials.
