Standardized tests have always been a part of the application process for becoming a PA, and the GRE was the only test around when I was going through applications. While the MCAT is sometimes accepted, it often isn’t a preferred requirement by programs, but the PA-CAT is a similar knowledge-based test focusing on the main prerequisite subjects required for PA school. Here are some similarities and differences between the PA-CAT vs GRE and how to prepare.
PA-CAT vs GRE: PA School Requirements
As a pre-PA coach, I’ve been getting more and more questions about the PA-CAT since it launched, with the main one being, “What is it?” With the ever-changing application process for PA school, it’s important to stay up to date on changes to requirements with each of the programs you plan to apply to, and know the differences between the PA-CAT vs GRE.
I applied to PA school 10 years ago, and if you asked me to predict how the process would change, my guess would be more standardization between prerequisites, testing, and deadlines. That hasn’t been the case, as programs have even more variety in requirements now.
With schools receiving thousands of applications, they use various standards when going through the applicant pool, and programs determine their particular requirements based on what they think will result in the most successful students. These prerequisite requirements can change even between cycles as schools try to fine-tune the process.
What is the GRE?
Traditionally, the GRE has been used as an application factor for PA programs. Since PA school is a master’s level program, it’s common for a standardized test to be a requirement.
The GRE is a strategy-based test focused on basic math in the quantitative section and vocabulary skills in the verbal section. A writing section is also included but not typically important for PA programs. There are also specific subject GRE tests, but for the purposes of applying to PA school, only the general test is required.
While the GRE has been a common requirement for many years, there is still a lack of significant data to show a direct correlation between GRE scores and success in PA school or passing the PANCE (the standardized test required at the end of PA school).
What is the PA-CAT?
More recently, the PA-CAT was developed specifically based on the typical prerequisite requirements of most PA schools. The topics covered include anatomy, physiology, general biology, general and organic chemistry, biochemistry, microbiology, behavioral sciences, genetics, and statistics.
While that may seem more intimidating than a strategy test, there are some benefits as well. The PA-CAT can help identify areas you may struggle with before starting PA school. It’s also scored in the same way as the PANCE, so PA schools are using this exam to see if there is a correlation in performance on the PA-CAT and more success in PA schools.
While PA schools want you to do well in their programs and graduate, the average attrition rate is 6.63% in 2023 according to the ARC-PA 2023 report. A knowledge-based test like the PA-CAT may be a way for programs to distinguish which students will complete PA school since the rigor of undergraduate courses can vary.
Another benefit to the exam is an opportunity to show another strength on your application if you have a below-average GPA or a rough semester freshman year. The PA-CAT could prove to be a strong marker that schools look at when holistically assessing applicants.
