How to Become a CRNA (Nurse Anesthetist Requirements)

A certified registered nurse anesthetist (CRNA) safely administers anesthesia before, during, and after medical procedures. It's high-responsibility work tied to some of the most critical moments in a patient's care, and it demands extensive education and experience. CRNAs also earn the highest salaries among advanced practice registered nurses (APRNs).

CRNAs work in hospitals, surgery centers, medical offices, and dental clinics, administering anesthesia for surgical, obstetric, and trauma procedures. They collaborate with doctors and other nurses to build a pain management plan for each patient, delivering anesthesia by injection, inhalant, or oral route.

CRNA Education Requirements

You need a graduate degree and national certification to become a CRNA, and the bar has moved to a doctorate. The Council on Accreditation of Nurse Anesthesia Educational Programs (COA) stopped accrediting new master's-level programs, and students entering the field after 2022 must earn a doctoral degree to become certified. A doctorate is the entry standard for new CRNAs as of 2025.

The most common doctoral choice is the Doctor of Nursing Practice (DNP). Other options include the Doctor of Philosophy (PhD), Doctor of Education (EdD), and Doctor of Nursing Science (DNS). Nurses can also pursue a Doctor of Nursing Anesthesia Practice (DNAP).

The shift to doctoral preparation has strong backing. The American Association of Colleges of Nursing has called for doctoral preparation for all APRNs since 2004, and the move was the result of a long, deliberate evaluation by the field rather than a sudden decision.

Prerequisites

Before entering a CRNA program, you must be a registered nurse (RN) with a Bachelor of Science in Nursing (BSN). You'll also need at least one year of experience in an acute care setting such as an intensive care unit (ICU) or emergency room, though many schools want more. To strengthen an application, some nurses earn the critical care registered nurse (CCRN) certification.

Confirm any program you apply to is accredited by the COA. You must graduate from an accredited program to sit for the certification exam.

What You'll Study

Accredited nurse anesthetist programs cover:

• Anesthesia pharmacology
• Chemistry, biochemistry, and physics
• Anatomy, physiology, and pathophysiology
• Anesthesia equipment and technology
• Pain management
• Statistics and research
• Professional and legal aspects of nurse anesthesia practice

You'll also complete supervised clinical practice at a university-based or large community hospital, gaining experience across a wide range of procedures from labor and delivery to open-heart surgery.

How Long It Takes

Becoming a CRNA takes a minimum of seven years:

• Bachelor's degree in nursing: about four years
• RN licensure: after completing the bachelor's
• Acute care experience: at least one year
• Graduate degree in nurse anesthesia: two to four years
• CRNA certification: after completing the graduate degree
• State licensing: after passing the certification exam

Doctoral timelines vary by starting point. A BSN holder can expect three to four years in a full-time doctoral program, while someone who already holds a master's may finish in one to two years. A BSN-to-DNP program runs three to four years, compared with five to six to complete an MSN and then a doctorate.

Certification

After your graduate program, you're eligible to take the certifying exam from the National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA). The computerized test runs a minimum of 100 questions, up to 170, until it can determine with certainty whether you passed. Once you pass, your certification is sent to your state board of nursing, where you complete any remaining state steps.

Renewal and Continuing Education

To keep national certification, you follow the NBCRNA's Continued Professional Certification (CPC) Program. The NBCRNA evaluates CRNAs on an eight-year cycle made of two four-year periods. Every four years you complete 60 Class A credits (directly related to anesthesia care delivery or improvement) and 40 Class B credits (anesthesia practice or professional development, such as patient safety, public education, and research), plus four core modules covering airway management, applied clinical pharmacology, physiology, pathophysiology, and anesthesia equipment and technology (the equipment module doesn't apply during your first four-year cycle).

Every two years, you complete an online checkin to confirm your state license and continued practice. At the end of each eight-year cycle, you take the CPC Assessment, a 150-question exam on the four core modules. It isn't pass/fail, but falling short of the performance standard means completing additional continuing education to maintain certification.

What a CRNA Does

The day-to-day work centers on patients:

• Requesting diagnostic studies and reviewing medical histories
• Developing the anesthetic plan
• Discussing side effects and risks with patients and families
• Preparing and administering anesthesia
• Performing spinal, epidural, or nerve blocks
• Monitoring vital signs during and after surgery to prevent and manage complications
• Responding to emergencies with medication, airway management, or life support

Many CRNAs also take on administrative duties like ordering medications, managing budgets, and training staff. Some teach development courses, serve on state boards of nursing, or join organizations that set practice standards.

CRNA vs. Anesthesiologist

Both administer anesthesia. The difference is title and education. Anesthesiologists are medical doctors (MDs) who complete at least four years of post-graduate education plus a four-year residency, and they earn higher salaries. Smaller offices tend to employ CRNAs over anesthesiologists. Some states require CRNAs to work under physician supervision; others allow independent practice.

Salary and Job Outlook

The mean annual wage for nurse anesthetists was $223,210 as of May 2024, with a median around $212,650, the highest earning potential among APRNs by a wide margin.

The BLS groups nurse anesthetists with nurse midwives and nurse practitioners and projects 35% employment growth for the group from 2024 to 2034, far above the average for all occupations, with about 32,700 openings a year. Growth specific to nurse anesthetists is more modest, but still strong.

Advancing Your Career

Two reliable ways to move up or raise your pay. First, tailor your education toward a patient population, condition, or surgical subfield. Common concentrations include obstetrics, pediatrics, neurosurgery, cardiovascular, and dental surgery, and the related professional organizations help with networking and job searches.

Second, target high-paying settings and locations. General medical and surgical hospitals and outpatient care centers report above-average CRNA salaries, and several of the top-paying metro areas post median pay above $200,000, according to the BLS.
