How to Become a CRNA

What Is a CRNA and Why Pursue This Career?

A Certified Registered Nurse Anesthetist (CRNA) is an advanced practice registered nurse who administers anesthesia for surgeries, diagnostic procedures, and pain management. CRNAs work in hospitals, surgical centers, dental offices, pain clinics, and military facilities. In many rural and underserved communities, they serve as the sole anesthesia provider.

Nurse anesthesia ranks among the highest-paying nursing specialties in the United States. CRNAs earned an average of $214,000 per year in 2025, according to the Bureau of Labor Statistics. In high-demand states like California, Texas, and New York, salaries frequently exceed $250,000. For a detailed breakdown by location, see our CRNA salary by state guide.

Job growth projections remain strong. The BLS projects 38% growth for nurse anesthetists through 2032, far outpacing most healthcare occupations. An aging population, expanding surgical volume, and a nationwide push to reduce healthcare costs all drive this demand. With over 130 accredited programs across the country, aspiring CRNAs have more training options than ever before.

STEP 1 Earn Your Bachelor of Science in Nursing (BSN)

Every CRNA path starts with a four-year BSN from an accredited nursing program. While some nurses enter practice with an associate degree, CRNA programs universally require a bachelor's degree. If you already hold an ADN, RN-to-BSN bridge programs can take as few as 12 to 18 months online.

Key Prerequisites and GPA Targets

Your undergraduate coursework must include anatomy, physiology, microbiology, organic or biochemistry, statistics, and pharmacology. Programs evaluate your overall GPA along with your science GPA separately. Most require a minimum cumulative GPA of 3.0, but competitive applicants carry a 3.3 or higher. Top-tier programs at schools in states like Pennsylvania and Illinois often admit students with averages between 3.5 and 3.7.

Focus on excelling in the sciences early. A strong foundation in chemistry, biology, and advanced anatomy directly prepares you for the pharmacology and physiology coursework in nurse anesthesia programs. A weak science GPA is difficult to overcome later, even with excellent clinical experience.

Pass the NCLEX-RN

After graduating from your BSN program, you must pass the National Council Licensure Examination for Registered Nurses (NCLEX-RN) to earn your RN license. This is a non-negotiable requirement. You cannot accrue the ICU experience that CRNA programs demand without an active RN license.

STEP 2 Gain ICU Experience

Critical care experience separates CRNA applicants from other advanced practice nursing candidates. Every accredited program requires a minimum of one year of ICU nursing as a registered nurse. Most successful applicants bring two or more years to the table, and some programs will not consider candidates with less than two years.

Best ICU Settings for CRNA Applicants

Not all ICU experience carries equal weight. Programs favor units where nurses routinely manage hemodynamically unstable patients, titrate vasoactive drips, and work closely with ventilator settings. The most valued ICU types include:

• Surgical ICU (SICU) — Direct exposure to post-operative patients, invasive monitoring, and rapid clinical decision-making
• Cardiovascular ICU (CVICU) — Swan-Ganz catheters, intra-aortic balloon pumps, post-cardiac surgery management
• Neuro ICU — Intracranial pressure monitoring, complex pharmacological interventions, acute neurological emergencies
• Medical ICU (MICU) — Accepted by most programs, especially with high-acuity patients on multiple drips and mechanical ventilation
• Trauma ICU — Fast-paced, high-acuity patients with multi-system injuries

Emergency departments, step-down units, and pediatric floors generally do not satisfy the ICU requirement. If your hospital calls a unit "progressive care" or "intermediate care," confirm with your target programs that they accept it before banking years of experience there.

CCRN Certification

The Critical Care Registered Nurse (CCRN) certification from the American Association of Critical-Care Nurses is not universally required, but it gives you a measurable edge. Several programs list it as a preference or soft requirement. Beyond admissions, studying for the CCRN reinforces the hemodynamic and pharmacological knowledge that forms the backbone of anesthesia training.

STEP 3 Meet Program Prerequisites

CRNA program prerequisites extend beyond GPA and ICU experience. Each program sets its own requirements, but several elements appear across nearly every application.

GRE Scores

Some programs still require the Graduate Record Examination (GRE), though many have dropped it in recent years. Where required, aim for scores above the 50th percentile. Check your target programs early since the GRE takes time to prepare for, and scores are valid for five years. Programs at schools in Ohio, North Carolina, and other states vary widely on this requirement.

Letters of Recommendation

Most programs ask for two to three letters. At least one should come from an ICU charge nurse or nurse manager who can speak to your clinical judgment. A CRNA who has observed your work is ideal for a second letter. Avoid generic letters from professors who last saw you years ago. Specificity matters: the letter should reference actual patient scenarios where you demonstrated critical thinking.

Personal Statement

Your personal statement needs to answer three questions: Why anesthesia? Why now? Why this program? Avoid vague sentiments about wanting to help people. Instead, describe a specific moment in the ICU that solidified your decision. Maybe you watched a CRNA manage a difficult airway during a rapid sequence intubation and realized you wanted that level of autonomy. Concrete stories beat abstract motivation every time.

Shadow Hours

Many programs require or strongly recommend shadowing a CRNA for 8 to 40 hours. Shadowing demonstrates genuine interest and gives you material for your personal statement and interviews. Contact your hospital's anesthesia department or reach out to CRNAs through the American Association of Nurse Anesthesiology (AANA) to arrange observation time.

STEP 4 Apply to CRNA Programs

Most CRNA programs use the centralized application portal NurseCAS (Nursing Centralized Application Service). Applications typically open in the spring for classes starting the following January or May. Deadlines vary by program, but many fall between June and October.

Application Timeline

• 12-18 months before — Research programs, begin shadowing, request letters of recommendation
• 6-12 months before — Take the GRE if required, draft your personal statement, complete prerequisite courses
• Application window — Submit NurseCAS application, program-specific supplements, and transcripts
• 2-4 months after deadline — Interview invitations go out on a rolling basis

Competitive Applicant Profile

Based on recent admissions data across 130+ accredited programs, strong applicants typically present:

• Cumulative GPA of 3.3 or higher (science GPA of 3.2+)
• Two or more years of adult ICU experience in a high-acuity setting
• Active CCRN certification
• GRE scores above the 50th percentile (where applicable)
• 8 to 40 hours of CRNA shadowing
• ACLS, BLS, and PALS certifications

Interview Tips

CRNA interviews often include clinical scenarios. You might be asked how you would respond to a patient desaturating in the OR or describe your approach to a crashing post-op patient. Draw directly from your ICU experience. Programs want to see that you can think systematically under pressure, communicate clearly, and recognize your own limitations. Prepare by reviewing common hemodynamic scenarios, acid-base interpretation, and basic pharmacology of anesthetic agents.

STEP 5 Complete Your Doctoral Program

As of 2025, all new CRNA programs must award a doctoral degree. The two most common are the Doctor of Nursing Practice (DNP) and the Doctor of Nurse Anesthesia Practice (DNAP). Both qualify graduates to sit for the national certification exam, and employers treat them interchangeably.

DNP vs. DNAP

The DNP emphasizes evidence-based practice, healthcare systems leadership, and quality improvement alongside anesthesia clinical training. The DNAP focuses more narrowly on anesthesia science and practice. Neither degree carries a clear advantage in the job market. Choose based on program location, clinical sites, faculty expertise, and total cost.

Program Structure

Most programs run 36 months (three years) of full-time study. The first year covers foundational sciences: advanced pharmacology, advanced physiology and pathophysiology, chemistry and physics of anesthesia, and principles of anesthesia practice. Clinical rotations begin in the second year and intensify in the third.

Students must complete a minimum of 2,000 clinical hours across diverse case types including general surgery, obstetric anesthesia, pediatric anesthesia, regional anesthesia, cardiac cases, and pain management. By graduation, most students have administered anesthesia for 600 to 800 cases spanning all major surgical specialties.

Cost Range

Program costs range from approximately $48,000 at public institutions to $178,000 or more at private universities. States like Florida and Michigan offer several programs on the lower end of the cost spectrum, while programs in major metropolitan areas tend to be more expensive. Federal loans, scholarships through the AANA Foundation, military service commitments, and employer tuition reimbursement can offset these costs. For a full comparison, see our CRNA school cost guide.

STEP 6 Pass the National Certification Exam (NCE)

After graduating from an accredited program, you must pass the National Certification Examination (NCE) administered by the National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA). This exam is the final barrier between you and clinical practice.

Exam Format

The NCE is a computer-based test with 170 questions (100 scored, 70 pretest items that do not count toward your score). You have three hours to complete the exam. Questions cover all domains of nurse anesthesia practice: basic sciences, equipment and technology, basic and advanced anesthesia principles, and professional aspects of practice.

Pass Rate

The national first-time pass rate stands at approximately 89% as of 2025. Programs with strong clinical training and integrated board-style exams throughout the curriculum tend to produce higher pass rates. If you do not pass on the first attempt, you can retake the exam after a 60-day waiting period, with up to four attempts within a 24-month window.

Preparation typically involves a combination of review courses (Valley Anesthesia, Apex Anesthesia, CORE), question banks, and study groups. Most graduates spend four to eight weeks in dedicated study between graduation and their exam date.

STEP 7 Get Licensed and Start Practicing

Passing the NCE earns you the CRNA credential, but you still need a state license to practice. Each state board of nursing issues APRN licenses for nurse anesthetists. Requirements vary, but most involve submitting proof of your doctoral degree, NCE pass, and current RN license, along with state-specific application forms and fees.

Practice Authority Varies by State

State laws govern the degree of independence a CRNA has. As of 2026, approximately 23 states grant full practice authority (FPA), allowing CRNAs to practice without a collaborative agreement with a physician or anesthesiologist. Other states require some form of physician supervision or collaboration. The trend is moving toward expanded autonomy, especially in states with rural healthcare shortages.

States like Virginia and North Carolina have recently expanded CRNA practice authority, while states like California and Texas continue to require varying levels of physician involvement. Research the practice environment in the state where you plan to work before committing to a job.

Finding Your First Position

New CRNAs have strong leverage in the job market. Hospitals, ambulatory surgery centers, and anesthesia groups actively recruit graduating students, often extending offers before graduation. Common first-job settings include:

• Hospital-based practices — Steady case volume, built-in mentorship, benefits packages
• Anesthesia management groups — National companies like NorthStar and US Anesthesia Partners that staff multiple facilities
• Ambulatory surgery centers — Shorter cases, more predictable schedules, growing sector
• Government and military — VA hospitals, military installations, and federal facilities offer competitive pay with full benefits and loan repayment programs

Negotiate beyond base salary. Signing bonuses of $15,000 to $50,000 are common, and many employers offer student loan repayment, relocation assistance, and continuing education allowances. For salary benchmarks by state, see our CRNA salary by state guide.

Timeline Summary: BSN to CRNA

Here is the full path from starting your BSN to your first day as a practicing CRNA.

Tips for a Strong CRNA Application

Competition for CRNA program seats remains fierce, with many programs accepting fewer than 20% of applicants. These strategies help you stand out.

1. Prioritize your science GPA. Programs scrutinize your performance in anatomy, physiology, pharmacology, and chemistry more heavily than your overall GPA. Retake courses if needed before applying.
2. Choose your ICU strategically. Transfer to a high-acuity unit if your current assignment involves primarily stable, monitored patients. SICU and CVICU experience consistently ranks highest with admissions committees.
3. Earn the CCRN early. Certification proves you can pass a rigorous, standardized exam and demonstrates commitment to critical care excellence. Study for it within your first year of ICU work.
4. Shadow multiple CRNAs. Observe in different settings: a busy trauma OR, an ambulatory center, and an obstetric suite. Varied exposure shows genuine curiosity and gives you richer material for essays and interviews.
5. Write a specific personal statement. Replace generic motivation with concrete clinical stories. Describe a moment that changed your trajectory, not a lifelong dream.
6. Prepare for clinical interview questions. Review acid-base balance, vasopressor pharmacology, ventilator management, and basic hemodynamic interpretation. Practice explaining clinical reasoning out loud.
7. Apply broadly. Submit applications to 5 to 10 programs across different regions to maximize your chances. Use our school directory to compare programs by state, cost, and acceptance rate.
