Certified Registered Nurse Anesthetist: How to Become a CRNA

Certified registered nurse anesthetists (CRNAs) are advanced practice nurses who specialize in anesthesia and pain management before, during, and after procedures. It is one of the longest paths in nursing and one of the best paid. This guide covers the requirements, the education and certification steps, the costs, and the salary and job outlook.

What a CRNA Does

A CRNA is an advanced practice registered nurse (APRN) trained to administer anesthesia and manage anesthesia-related care. You assess the patient beforehand, choose the type and dose of anesthesia, manage the airway and vital functions during the procedure, and oversee recovery. You work alongside surgeons, anesthesiologists, and other providers to keep patients safe and comfortable.

CRNAs are often the primary anesthesia provider, especially in rural and underserved areas. Nurse anesthetists are the sole anesthesia providers in most rural hospitals, which keeps surgical, obstetric, and trauma services running in those communities. The role carries real responsibility and a high degree of autonomy. CRNAs deliver tens of millions of anesthetics in the U.S. each year.

History of Nurse Anesthetists

Nurse anesthesia dates to the 1860s, when battlefield nurses like Catherine S. Lawrence administered chloroform during the Civil War, proving trained nurses could handle anesthesia under pressure.

By 1877, Sister Mary Bernard Sheridan at St. Vincent's Hospital in Erie, Pennsylvania, became the first full-time nurse anesthetist. Alice Magaw's record of more than 14,000 ether anesthetics at the Mayo Clinic earned her the title "Mother of Anesthesia."

Formal education began in 1909 with a course at St. Vincent Hospital in Portland, Oregon. Agatha Hodgins opened the Lakeside School of Anesthesia in 1915, trained military personnel in World War I, and helped found the group now known as the AANA in 1931. A 1934 California Supreme Court decision affirmed nurse anesthetists' right to practice independently, setting a national precedent.

Standardization followed: the first national certification exam in 1945, program accreditation in the early 1950s, and the "Certified Registered Nurse Anesthetist" title in 1956. Mandatory recertification began in 1978, and CRNAs secured direct Medicare Part B reimbursement in 1986. A 2001 CMS "opt-out" rule let many states waive physician-supervision requirements. Today the profession requires a doctorate for entry. From battlefield improvisation to doctorate-prepared clinicians, CRNAs have been part of American surgery for more than a century.

How to Become a CRNA

1. Become an RN with a BSN

Earn a Bachelor of Science in Nursing (BSN) and get your RN license. A BSN is the standard prerequisite for nurse anesthesia programs. If you already hold an associate degree or diploma, enroll in an RN-to-BSN program. Aim for a GPA of 3.0 or higher, since graduate admissions are competitive.

2. Gain Critical Care Experience

Work one to two years in an ICU or other acute care setting. Most programs require at least one year of full-time critical care experience. The Critical Care Registered Nurse (CCRN) credential is often required or strongly preferred. It calls for at least 1,750 hours of direct critical care in the previous two years plus passing the exam from the AACN Certification Corporation. This is where you build the clinical judgment anesthesia training depends on.

3. Earn a Doctoral Degree from a CRNA Program

Enroll in a Council on Accreditation (COA)-accredited program and earn a Doctor of Nursing Practice (DNP) or Doctor of Nurse Anesthesia Practice (DNAP). As of 2025, all new CRNAs must graduate with a doctorate.

Programs run 36 to 51 months and combine classroom work in pharmacology, physiology, pathophysiology, and anesthesia principles with several thousand hours of clinical rotations. Current CRNAs who hold master's credentials remain fully qualified, but anyone entering now will do so with a doctorate.

4. Pass the National Certification Exam (NCE)

After your program, sit for the National Certification Examination administered by the National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA). It is a computer-adaptive exam covering the full range of anesthesia practice.

Once your program director certifies your eligibility, register online with the NBCRNA, pay the exam fee ($1,285), and choose a testing center. You get a 90-day window to test.

About two months out, ramp up with review courses, adaptive practice questions, and the NBCRNA Self-Evaluation Exam to find weak spots. Study groups and mentors help. First-time pass rates currently run 85 to 90 percent.

When you pass, you earn the CRNA credential and appear in the NBCRNA registry. Initial certification lasts four years under the Continued Professional Certification (CPC) cycle. If you do not pass, you can retake the NCE up to three more times within a five-year window. Most retakers succeed on the second or third attempt.

5. Obtain State Licensure and Begin Practice

Submit proof of your active RN license, your doctorate, and your NBCRNA certification to your state Board of Nursing, along with fees (typically $100 to $300) and a background check. Some states issue a standalone CRNA license; others annotate your RN license. Scope rules vary: a dozen-plus opt-out states allow fully independent practice, while others require MD supervision. Renew your state license on schedule, usually every one to two years, and keep up with continuing education.

6. Maintain Certification and Skills

Maintaining the credential runs through the NBCRNA's CPC program. Every four years you earn a mix of Class A (assessed) and Class B (professional development) credits and complete four core modules: airway management, pharmacology, physiology and pathophysiology, and anesthesia equipment. Every eight years you take the CPC Assessment, a non pass/fail exam that flags knowledge gaps. Keep your RN/APRN license active throughout.

What It Costs to Become a CRNA

A CRNA education is a major commitment, but with starting salaries north of $210,000 the payback is usually fast. Tuition for a three- to four-year DNP/DNAP program ranges from about $60,000 at an in-state public university to more than $200,000 at private or out-of-state schools. Budget another $15,000 to $30,000 a year for living expenses, which adds $45,000 to $90,000 over the program.

Before you start, plan for pre-admission costs: a GRE fee (about $220), optional CCRN certification ($255 to $370), and $4,000 to $10,000 for textbooks, simulation supplies, and study prep. Compliance requirements like background checks, drug screenings, and immunization tracking run $60 to $225 a year. After graduation, the NCE costs $1,285 and state licensure runs $100 to $300.

Total out-of-pocket investment usually lands between $115,000 and $130,000 for an in-state public program, up to $310,000 for a high-end private track. Most CRNAs recoup the cost within a few years through six-figure salaries, sign-on bonuses, and loan-repayment incentives.

What CRNAs Earn

CRNAs are the highest-paid nursing specialty and rank among the top-paying occupations in the country.

According to the U.S. Bureau of Labor Statistics, the median annual wage for nurse anesthetists is $212,650, with a mean of $223,210 (May 2024). That outpaces other advanced practice nurses by a wide margin: nurse practitioners and nurse midwives earn a median around $129,000 to $132,000. Experienced CRNAs in high-paying regions or specialty roles often clear $250,000.

Salary by State

Pay varies sharply by location. Northeastern and some Midwestern states report the highest averages, while parts of the South and Mountain West run lower. Illinois leads at roughly $281,000, followed by Massachusetts ($272,000), Montana ($256,000), New York ($256,000), and Vermont ($255,000). Lower-paying states include Utah (about $125,900), Alabama ($173,400), and Florida (around $177,000). Even the lower figures sit well above the national median wage across all jobs, and high-pay states are often offset by higher cost of living.

Salary by Setting

Physicians' offices and medical groups (anesthesia groups, surgeons' offices, pain clinics) employ the most CRNAs, roughly half the workforce, often at competitive pay. Hospitals, especially general surgical hospitals, are next, with CRNAs working in operating rooms, obstetric units, and critical care. Hospital pay may run slightly lower on average than private groups but still very high, with benefits.

Outpatient surgical and ambulatory care centers handle same-day procedures and pay can match hospitals. A smaller number of CRNAs work in academia, the military, or VA hospitals. Leadership roles, travel assignments, extra call, and subspecialties like cardiac anesthesia or chronic pain raise earnings further.

Job Outlook

Demand is strong. BLS projects the broader category of nurse anesthetists, nurse midwives, and nurse practitioners will grow 35 percent from 2024 to 2034, much faster than the roughly 4 percent average for all occupations, with about 32,700 openings a year. Nurse anesthetists specifically grow more modestly, around 10 percent over the decade. The AANA represents more than 60,000 CRNAs nationwide.

The drivers are an aging population needing more procedures and hospitals seeking cost-effective anesthesia providers amid physician shortages. In rural areas, where most counties rely on CRNAs, nurse anesthetists keep surgical services running. Opt-out laws in many states expand CRNA autonomy. Unemployment in the field is very low, and many regions recruit with signing bonuses and loan repayment. States with the highest CRNA employment include Florida, Texas, Michigan, Ohio, and Pennsylvania.
