How to Become a CRNA: A Step by Step Guide
8 min read
A Certified Registered Nurse Anesthetist (CRNA) is an advanced practice nurse who delivers anesthesia. Becoming one takes most people about 7 to 10 years from the start of nursing school, and every step builds toward the next.
Here is the path from registered nurse to CRNA, and what each stage actually asks of you.
1. Earn a BSN and become a registered nurse
You need a Bachelor of Science in Nursing and an active RN license. If you already hold an associate degree and an RN license, an RN to BSN bridge program gets you there.
Grades matter more than they feel like they should at this stage. Nurse anesthesia programs look closely at science coursework, so protect your GPA in anatomy, physiology, chemistry, and pharmacology.
2. Get high-acuity ICU experience
Every accredited program requires critical care experience, usually at least one year, and competitive applicants often have more. The type of ICU counts. Committees care that you managed vasoactive drips, ventilators, and unstable patients with real autonomy.
A high-acuity unit such as a surgical, cardiac, or medical ICU at a larger hospital gives you the cases and the stories you will need for your application and interview.
3. Earn the CCRN and strengthen your file
The CCRN certification signals that you know critical care at a deeper level than the floor. Beyond the certificate, be ready to speak to the physiology behind it.
This is also the window to fix a weak spot. Retaking a science course or taking a graduate-level physiology or pharmacology class can move a borderline application into range.
4. Complete a doctoral program and pass the NCE
As of 2022, all new nurse anesthesia programs award a doctoral degree (DNP or DNAP), and full-time programs typically run 36 to 42 months. You cannot work as a nurse during most of it, so plan for the financial gap.
After graduation you sit for the National Certification Examination (NCE). Passing it earns the CRNA credential, and you maintain it through continued practice and recertification.
Frequently asked questions
How long does it take to become a CRNA?
About 7 to 10 years from the start of nursing school: a 4 year BSN, at least 1 year of ICU experience (often more), and a 3 to 3.5 year doctoral nurse anesthesia program.
What degree do you need to be a CRNA?
You need a BSN to enter a program, and since 2022 all new nurse anesthesia programs award a doctorate (DNP or DNAP), so new CRNAs graduate with a doctoral degree.
Do you need ICU experience to become a CRNA?
Yes. Accredited programs require critical care experience, usually at least a year, and the acuity of your unit matters as much as the time you spend there.
