How to Become a CRNA

Certified Registered Nurse Anesthetists (CRNAs) administer anesthesia and manage patients through surgical and other procedures. It’s one of the most rigorous and competitive advanced practice nursing paths, generally requiring significant critical care experience before graduate school even begins.

Requirements vary by school and state. Always confirm current details directly with programs you’re considering and your state’s board of nursing.

Step 1: Become an RN with a BSN

As with other advanced practice paths, you’ll need an active RN license and a BSN before applying to nurse anesthesia programs.

Step 2: Gain critical care experience

This is the step that most distinguishes the CRNA path; nurse anesthesia programs typically require a meaningful amount of full-time experience in a critical care setting, most commonly an ICU, before you’re even eligible to apply. This isn’t a formality; the hands-on experience managing critically ill patients is considered essential preparation for the role.

Step 3: Complete a nurse anesthesia program (MSN or DNP)

Nurse anesthesia programs are graduate-level (MSN or increasingly DNP) and highly structured, combining rigorous coursework in pharmacology and physiology with extensive supervised clinical anesthesia hours. Programs are competitive to get into and demanding once enrolled, generally taking around 2.5-3 years to complete.

Step 4: Pass the National Certification Examination

After graduating, candidates take the National Certification Examination (NCE) to become a Certified Registered Nurse Anesthetist.

Step 5: Get licensed as an APRN in your state

Like other advanced practice roles, certification is followed by applying for APRN licensure through your state’s board of nursing.

Where CRNAs work

Hospitals (particularly surgical departments), outpatient surgical centers, obstetric units, and pain management clinics. CRNAs are the primary anesthesia providers in many rural areas of the country, where their role can be especially independent.

Is this path right for you?

Because of the critical care experience requirement and program rigor, becoming a CRNA is generally a longer and more demanding road than other NP specializations but it’s also one of the more specialized and highly compensated nursing roles for those drawn specifically to anesthesia and perioperative care.
