CRNA School Requirements

Every CRNA program accredited by the COA requires five core credentials: a BSN, an active RN license, ICU experience, a competitive GPA, and current certifications. The BSN must come from an accredited nursing program, though some schools accept ADN-to-BSN bridge graduates. ICU experience ranges from 1 to 2 years depending on the program, and most want adult critical care specifically (MICU, SICU, CVICU, or CCU). Certifications like ACLS and BLS are universal, and 74 programs also require CCRN before admission. Your GPA minimum will typically sit around 3.04, but the rest of your profile (experience quality, interview, references) carries real weight too. At The CRNA Club, we track all 154 programs so you can see exactly which requirements apply to your target schools.

Currently 105 of 154 CRNA programs (68%) do not require the GRE. That number has been climbing each year as more programs drop the exam from their admissions criteria. Schools that still require it typically accept scores within the 50th percentile range, and a few accept the MAT as a substitute. If your target programs don't require the GRE, spending that study time on prerequisite courses or CCRN prep gives you more return on effort. For programs that do require it, most applicants spend 4 to 8 weeks preparing. You can filter programs by GRE requirement in The CRNA Club's free School Database to see exactly where you stand.

The average minimum GPA across 154 CRNA programs is 3.04. That is a floor, not a target. Competitive applicants typically carry a 3.5 or higher, and some top programs report average accepted GPAs above 3.7. Still, 125 programs accept applicants with GPAs of 3.0 or below, so a lower GPA does not automatically disqualify you. Programs often evaluate science GPA separately from cumulative GPA, and strong performance in prerequisites like chemistry and anatomy can offset a weaker overall number. Retaking a course to replace a C with an A shows programs you are serious. Want to see where your GPA stands?

Most CRNA programs require between 1 and 2 years of adult ICU experience at the time of application. 128 programs accept just 1 year, while 24 programs want 2 or more years. Quality matters as much as quantity here. Programs want to see that you have managed high-acuity patients on drips like vasopressin, levophed, and propofol, and that you are comfortable with hemodynamic monitoring and ventilator management. Units like MICU, SICU, CVICU, and CCU are preferred because they expose you to the pharmacology and critical thinking that CRNA school builds on. If your unit handles post-cardiac surgery patients or ECMO, that experience stands out on applications.

Out of 154 programs, 76 do not require CCRN for admission. Some of those schools let you earn it during your first year of the program instead. That said, having your CCRN before you apply sends a strong signal to admissions committees. The exam covers adult critical care nursing across cardiovascular, pulmonary, neuro, and multisystem topics, which directly maps to CRNA school content. Most nurses study 6 to 12 weeks using practice exams and review courses. Even when a program lists CCRN as "preferred" rather than "required," applicants with the certification tend to have stronger applications overall. You can filter programs by this requirement in The CRNA Club's free School Database.

Yes. 89 CRNA programs currently accept NICU experience as qualifying critical care. These programs recognize that neonatal intensive care involves complex pharmacology, ventilator management, and high-acuity patient monitoring. The main concern programs have with NICU experience is the lack of adult hemodynamic management, so some NICU nurses choose to cross-train in an adult ICU for 6 to 12 months to strengthen their applications. Programs that accept NICU tend to view the skill set favorably because of the precision required with tiny doses and delicate patients. If you are a NICU nurse considering CRNA school, building a target list of programs that accept your experience early saves you from applying to schools that will screen you out.

The most common CRNA prerequisites are chemistry, organic chemistry, biochemistry, statistics, physics, and anatomy and physiology. Requirements vary widely across programs. 113 programs do not require organic chemistry, 138 skip physics, and 68 do not require statistics. That variation means your prerequisite workload depends entirely on which schools you target. Most programs want prerequisites completed within 5 to 7 years of your application date, so timing matters if you finished your BSN a while back. We cover each prerequisite in detail on our CRNA prerequisite courses page, including which programs waive specific courses.

92 programs do not require CRNA shadowing hours for admission. For those that do, the typical range is 8 to 40 hours of observing a practicing CRNA in the operating room. Shadowing gives you a realistic picture of the daily workflow, from intubations and regional blocks to managing emergencies under anesthesia. It also gives you concrete stories for your personal statement and interview answers. To find shadowing opportunities, contact the anesthesia department at your hospital or reach out to CRNAs through your state AANA chapter. Even if your target programs do not require it, shadowing makes your application more credible because it shows you understand what the job actually looks like.
