Let’s be honest. Getting into a Physician Assistant program is a gauntlet. If you’re looking at the Rush University PA program prerequisites, you already know this isn’t just about checking boxes on a website. It’s about surviving a cutthroat selection process at one of the top-ranked programs in the United States. Rush University Medical Center in Chicago isn't just a school; it’s a massive academic health system, and their PA program—officially the Master of Science in Physician Assistant Studies—is designed to throw you into the deep end of clinical practice almost immediately.
You need a plan.
Most people look at the GPA requirements and think they're safe. They aren't. Rush receives thousands of applications for a tiny cohort of around 30 students. That is a terrifyingly small window. To squeeze through, you have to understand that "minimums" are essentially "failures" in the eyes of the admissions committee.
The GPA Reality Check
The formal word from Rush is that you need a minimum cumulative GPA of 3.0 and a science GPA of 3.0 on a 4.0 scale. Cool. Except, if you show up with a 3.0, your application is likely going straight into the digital recycling bin.
Competitive applicants usually hover around a 3.6 or higher. They want to see that you didn't just pass Organic Chemistry; they want to see that you owned it. If you had a rough freshman year, you've got to show an upward trend. They look at the last 60 hours of coursework very closely. If you bombed "Bio 101" in 2021 but aced "Advanced Genetics" in 2024, you're still in the game.
One thing that catches people off guard is how they calculate these numbers. Rush uses CASPA (Centralized Application Service for Physician Assistants). CASPA re-calculates every single grade you’ve ever received. Did you retake a class? Too bad. CASPA averages the two grades together. You can't hide that 'D' you got in Freshman Calculus by replacing it with an 'A' later. Both exist. Both matter.
The Core Science Prerequisites You Can't Skip
Rush is picky. They require specific classes, and they don't really do "substitutions." You need to have these completed with a grade of "C" or better before you matriculate, though honestly, a "C" is a red flag.
- Anatomy and Physiology: You need two semesters of this. It has to include a lab. Most people do "A&P I" and "A&P II." If your school offers them separately, take both.
- Biology: Two semesters with labs. General Bio is fine, but upper-level stuff is better.
- Chemistry: Again, two semesters with labs. Usually, this is General Chemistry I and II, or one Gen Chem and one Organic.
- Microbiology: One semester. Lab required. No exceptions.
- Biochemistry: This is a big one. Some schools don't require it; Rush does. It must be an upper-division course. Taking "Intro to Bio-Organic-Life-Sciences" usually won't cut it. You need the real deal.
Statistics is also on the list. Just one course. Don't stress too much about which department it's from—Math, Psychology, or Sociology statistics are usually all fine as long as they cover the fundamentals.
The Shadowing and Patient Care Experience Gap
Here is where most applicants blow it. They focus so hard on the Rush University PA program prerequisites in the classroom that they forget the "Assistant" part of "Physician Assistant."

Rush expects clinical experience. While some programs technically say it's "recommended," Rush wants to see that you’ve actually touched a patient. We aren't talking about volunteering at the front desk of a hospital or handing out blankets. That’s "Health Care Experience" (HCE). You need "Patient Care Experience" (PCE).
What counts? Being a Scribe is okay, but it's bottom-tier for Rush. They prefer EMTs, Paramedics, Certified Nursing Assistants (CNAs), or Respiratory Therapists. You need to be making clinical decisions or performing procedures.
Shadowing is a separate beast. You should aim for at least 20 to 40 hours of shadowing a certified PA. It shows you actually know what the job entails. If you haven't seen a PA deal with a difficult patient or navigate a complex EMR system, how do you know you want the job? Rush faculty will sniff out a lack of genuine interest in the PA profession during the interview.
Why the GRE is Becoming a Ghost
Interestingly, many programs are dropping the GRE. As of the most recent cycles, Rush has moved away from requiring the GRE for the PA program. This is a huge relief for those who hate standardized testing. However, check the current cycle's specific manual every time you apply. Requirements in Chicago academia can shift like the wind off Lake Michigan. Instead of the GRE, they are leaning harder into your "Non-Cognitive" traits. They want to know if you're a decent human being who can handle stress, not just if you know what "synecdoche" means.
The "Rush Factor" and Mission Fit
Rush is an urban, service-oriented institution. If your resume is just high grades and zero community service, you’re not a "Rush fit." They love applicants who have worked with underserved populations. Did you volunteer at a free clinic? Did you work in an inner-city ER? Mention it.

The personal statement is your only chance to be a human before they decide to interview you. Avoid the cliché "I want to help people." Everyone wants to help people. Tell a story about a specific patient encounter that changed how you view medicine. Talk about why the PA role specifically—not MD, not NP—is your path.
Letters of Recommendation: Don't Ask Your Uncle
You need three. One must be from a PA or a physician who has watched you work with patients. One should be from a professor who can vouch for your brain. The third can be a supervisor.
Do not get a letter from a "family friend" who happens to be a doctor but hasn't supervised you clinically. The admissions committee sees right through that. It looks lazy. You want a letter that says, "I would trust this person to treat my own family."
Practical Steps to Take Right Now
If you are serious about the Rush University PA program prerequisites, you need to stop reading and start auditing your transcript.

- Map your timeline. Use a spreadsheet. List every prerequisite. Mark the ones you've finished, the ones you're in, and the ones you still need.
- Calculate your science GPA manually. Use the CASPA guidelines. If you’re below a 3.4, consider taking two "booster" classes like Immunology or Pathophysiology to prove you can handle high-level science.
- Audit your hours. If you only have 200 hours of PCE, you are behind. The average matriculant at a school like Rush often has 1,000 to 2,000 hours. If you need a job, go get your EMT-B or CNA certification this summer.
- Visit the campus. Or at least attend a virtual info session. Rush tracks "demonstrated interest." When you apply, you can mention specific things you learned about their "practitioner-teacher" model.
- Check your expiration dates. Some schools (including Rush, historically) want your science prerequisites to be recent—usually within the last 5 to 7 years. If you took Micro in 2015, you might have to retake it.
The window for the CASPA application usually opens in late April. Rush operates on a rolling admissions basis or has early deadlines compared to some state schools. Apply early. If you wait until the deadline in the fall, most of the interview spots are already gone. It's a first-come, first-served game in many ways.
Get your transcripts verified by June. If you're submitting in September, you're basically donating your application fee to the university without a real shot at an interview. Chicago is a great place to study medicine, but the competition is fierce. Start building the "clinical version" of yourself today.
