How to Become a CRNA (Certified Registered Nurse Anesthetist) – ICU Hours, Interview Prep, Cost & More

Becoming a Certified Registered Nurse Anesthetist (CRNA) is one of the most challenging—and rewarding—paths in advanced practice nursing. CRNAs provide anesthesia care in a variety of settings, from rural hospitals to major surgical centers.

Because of their advanced skills and critical responsibilities, CRNAs are among the highest-paid APRNs, with incredible job autonomy and demand across the U.S.

This guide walks you through every step to becoming a CRNA, including ICU experience requirements, school admissions, interview tips, costs, and what to expect on the certification exam.

What Does a CRNA Do?

CRNAs are licensed to:

• Administer all types of anesthesia (general, regional, local)

• Monitor patients throughout surgical procedures

• Manage pain and emergency airways

• Provide anesthesia care in labor & delivery, trauma, outpatient surgery, and more

They work independently in many states, especially rural or underserved areas, and often serve as the sole or as an independent anesthesia provider.

Step-by-Step: How to Become a CRNA

1. Earn Your RN and BSN

• A Bachelor of Science in Nursing (BSN) is required

• Already an RN? Complete an RN-to-BSN bridge program

2. Get ICU Experience

• Most programs require at least 1 year of full-time RN experience in a critical care setting (but 2–3 years is competitive, and schools are getting more and more competitive).

Tip: PACU, ER, and step-down are usually not accepted unless paired with critical care experience.

3. Apply to an Accredited CRNA Program

• All CRNA programs are now Doctor of Nursing Practice (DNP) or Doctor of Nurse Anesthesia Practice (DNAP)

• Programs last 36–42 months

• Must be accredited by the COA (Council on Accreditation of Nurse Anesthesia Educational Programs)

4. Ace the CRNA Interview

• Interviews are competitive and intense

• Common questions:

  • “Walk me through an ABG.”

  • “What would you do if your vented patient desaturated rapidly?”

  • “Tell us about a time you made a mistake at work.”

• They often include clinical scenarios, with some also having math questions or personality assessments

Pro Tip: Practice with mock interviews, and review pathophysiology and hemodynamics. This is often weeks to months of preparation.

5. Complete a DNP/DNAP Nurse Anesthesia Program

• Combines didactic, simulation lab, and clinical training

• Expect:

  • 2,000+ clinical hours

  • 600+ cases

  • Rotations in OB, cardiac, peds, neuro, and rural anesthesia

6. Pass the NCE (National Certification Exam)

• Administered by the NBCC

• Must pass to become a certified CRNA

7. Apply for State Licensure and Start Practicing

• Scope of practice varies by state — many allow full practice authority

How Long Does It Take to Become a CRNA?

• BSN- 4 years

• ICU RN Experience - 1–3 years minimum

• DNP/DNAP Program - 3 years (most common)

How Much Does It Cost to Become a CRNA?

It ranges wildly depending on location and private versus public schools:

• $40,000 – $200,000 in tuition alone

Return On Investment? The average CRNA salary is $180,000–$250,000/year, depending on location and setting.

Choosing the Right CRNA School

Look for programs with:

• High NCE pass rates

• Strong clinical site partnerships

• Experienced faculty (especially current CRNAs)

• Supportive academic culture

• Interview and test prep included in curriculum

Red Flags: Poor pass rates, few clinical rotation sites, or high attrition.

  • Basic Sciences

  • Equipment, Instrumentation, and Technology

  • Basic Principles of Anesthesia

  • Advanced Principles of Anesthesia

You get 3 hours to complete the exam.
