How to Become a CRNA: Requirements, Timeline, and What School Is Like
What are the steps to become a CRNA?
The path is well-defined, but each step gates the next, so plan it as a multi-year sequence rather than a checklist you can rush.
- Earn a BSN and pass the NCLEX-RN to become a registered nurse.
- Work at least one year full-time in a critical-care setting (most programs prefer adult ICU; CCRN certification is strongly recommended).
- Get admitted to a COA-accredited nurse anesthesia program (now doctoral — DNP or DNAP).
- Complete the program (~36 months) including didactics and a clinical residency with thousands of supervised anesthesia hours.
- Pass the National Certification Examination (NCE) from the NBCRNA to earn the CRNA credential.
What ICU experience do you need for CRNA school?
A minimum of one year of full-time critical-care experience is the near-universal requirement, but competitive applicants usually have more, in higher-acuity units. Programs want to see that you can manage unstable patients, titrate vasoactive drips, and interpret hemodynamics independently.
Adult ICU (especially high-acuity surgical, cardiac, or medical ICU) is the most widely accepted. Earning your CCRN and shadowing CRNAs strengthens an application significantly.
What is CRNA school actually like?
Nurse anesthesia programs are intense and largely front-loaded: heavy didactics in anesthesia pharmacology, physiology, and chemistry early, followed by a clinical residency where you administer anesthesia under supervision across surgical specialties.
Most programs are full-time and discourage or prohibit working, given the clinical hour requirements. Expect roughly three years of demanding, immersive training.
What's the exam — and what do CRNAs earn?
After graduating you sit the NCE, a computer-adaptive exam administered by the NBCRNA. Once certified, CRNAs maintain the credential through the Continued Professional Certification (CPC) program.
CRNAs are among the highest-earning APRNs, often well into the low-to-mid six figures, with significant variation by region, practice setting, and call burden. Benchmark against your specific market rather than national averages.
Frequently asked questions
How long does it take to become a CRNA?
About 7–8 years from the start of your BSN: roughly 4 years for the BSN, at least 1 year of ICU experience, and about 3 years in a doctoral nurse anesthesia program.
What ICU experience do I need for CRNA school?
At least one year of full-time critical-care experience, though competitive applicants usually have more in high-acuity units. Adult ICU is most widely accepted, and CCRN certification is strongly recommended.
Do I need a doctorate to become a CRNA?
Yes. As of 2022, all students entering accredited nurse anesthesia programs must be enrolled in doctoral programs (DNP or DNAP). Currently practicing CRNAs who trained earlier are not required to return for a doctorate.
Is CRNA school hard?
It's widely considered one of the most demanding nursing paths — front-loaded didactics plus a full-time clinical residency. Most programs discourage or prohibit outside work during training.
How much do CRNAs make?
CRNAs are among the highest-paid APRNs, commonly in the low-to-mid six figures, with wide variation by region, setting, and call. Benchmark against your local market.
