What is a certified registered nurse anesthetist (CRNA)? How long does it take to become a nurse anesthetist? This guide answers common questions about nurse anesthetist careers, including how to become a CRNA.

What Is a Nurse Anesthetist?

CRNAs are advanced practice registered nurses (APRNs) trained in anesthesia and pain relief. As APRNs, they can determine anesthesia and pain relief needs, administer anesthesia, and prescribe pain medications, including controlled substances.

Nurse anesthetists work in hospitals, surgical centers, clinics, and private practices. In some settings, especially clinics and rural healthcare facilities, they may act as the only anesthesia specialist, while in settings like hospitals they typically work with physician anesthesiologists.

This guide describes nurse anesthetist education, credentialing, and work in detail, while our nurse anesthetist career overview offers a broader picture of the profession.

Steps to Becoming a Nurse Anesthetist

It takes four years to earn a BSN. Some nurse anesthetists begin their careers by earning an associate degree in nursing (ADN), which takes two years. Many schools offer RN-to-BSN programs, and some master of science in nursing (MSN) programs include a bridge option for ADN-holders. Students with a bachelor's degree in a non-nursing field can enroll in an accelerated BSN program and earn a BSN in 2-3 years, depending on how many transferable credits they hold.

Prospective RNs must pass the National Council Licensure Examination for RNs (NCLEX-RN). This test, which is computer adaptive, takes up to six hours and covers topics such as conditions and treatments, nursing practice, the healthcare system, working as part of a healthcare team, and patient communications and education. RNs must also meet state requirements, such as passing a background check.

Most graduate nurse anesthetist programs require at least 1-3 years of experience in an intensive care unit or a critical care program. During this time, candidates must maintain an unencumbered nursing license.

Starting in 2022, the minimum degree requirement for CRNAs will be a doctor of nursing practice (DNP) or doctor of nurse anesthesia practice (DNAP) rather than an MSN. Students select a specialty area during DNP programs, while DNAP curricula are already specialized.

Most nurse anesthetist graduate programs require at least a 3.0 GPA, although some require or strongly prefer 3.5 and higher. Candidates also submit letters of recommendation and a personal essay or statement.

Read About Choosing a Specialization

Offered through the National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA), this computerized examination varies in length and covers all topics related to planning and administering anesthesia and managing anesthesia programs. These topics include but are not limited to physiology and anatomy, pharmacology and different types of anesthesia, administering and monitoring different types of anesthesia, and potential complications and how to address them.

Learn About Nurse Anesthetist Credentials

Professionals who want to practice advanced practice nursing in the nurse anesthetist specialty must earn licensure specific to their state. Licensing requirements vary by state.

Nurse anesthetists work in hospitals and surgical centers, typically in collaboration with physicians and other healthcare professionals as part of an anesthesia team. They also work in clinics, medical offices, and military bases, where they may lead an anesthesia team. In under-resourced environments like rural hospitals, they may be the only anesthesia practitioner. Individual states maintain different regulations on nurse anesthetists' scope of practice, including whether they hold full professional autonomy or must work under a physician's supervision. Depending on the state, many CRNAs have their own practice and work independently.

Nurse Anesthetist Schooling

Starting in 2022, nurse anesthetist schooling will take most students 7-8 years to complete as a DNP or DNAP will become the minimum required degree.

BSN Degree

While the minimum degree needed to earn an RN license is a two-year ADN degree, most graduate-level nursing programs require a BSN. Some graduate programs include a bridge component that allows ADN-holders to complete the equivalent of a BSN.

  • Admission Requirements: Most programs require or prefer a GPA of 3.0 or higher and successful completion of math and science programs, including biology and chemistry.
  • Program Curriculum: BSN programs include courses on anatomy and physiology, effective nursing practices, statistics, community health, and ethical issues.
  • Time to Complete: A high school graduate can usually earn a BSN in four years. Students with an ADN or a bachelor's degree in another field, especially the sciences or healthcare, can usually transfer in credits and finish in 2-3 years.
  • Skills Learned: BSN programs prepare nurses to administer tests and medications, monitor patients, understand and work in most healthcare settings and as part of a medical team, and educate patients on health topics.

Doctor of Nursing Practice

As of 2022, nurse anesthetists must hold a DNP or DNAP. The DNP is the highest practice degree a nurse can earn.

  • Admission Requirements: Most DNP/DNAP programs require or strongly prefer at least a 3.0 GPA from the undergraduate or MSN degree, an unrestricted RN license, 1-3 years experience in critical care, and professional references.
  • Program Curriculum: The curriculum includes epidemiology, pharmacology, safety and risk management, advanced evidence-based medical practice, organizational leadership, and healthcare legality. Programs also include clinical residencies.
  • Time to Complete: Students with an MSN can finish a DNP in 1-2 years. Students with a BSN can finish in 3-4 years.
  • Skills Learned: Nurse anesthetist students learn to apply research to new practices, use sound clinical judgment, employ technology, and other topics related to planning and administering anesthesia and providing pain relief.

Doctor of Nursing Practice vs. Doctor of Nurse Anesthesia Practice

There are a few educational options available to help CRNAs satisfy the new doctoral level degree requirement. The DNP and the DNAP are two popular degree options.

Doctor of Nursing Practice


As the terminal (highest) degree in nursing practice, the DNP is required for some university teaching positions. The DNP is available only from nursing schools. The American Association of Colleges of Nursing defines DNP standards and curricula. The DNP is more common than the DNAP. This doctoral degree focuses on practice rather than research, which is typical for a doctor of philosophy.

Doctor of Nurse Anesthesia Practice


The DNAP degree is available outside of nursing schools. The Council on Accreditation of Nurse Anesthesia approves programs. This doctoral degree is practice-focused but usually requires a capstone nursing research project on nurse anesthesia practice, education, or administration/management.

Nurse Anesthetist Credentials

Nurse anesthetists must be both certified and licensed to practice anesthesia. States administer licensure, while the NBCRNA manages nurse anesthetist certifications.

  • The NBCRNA certification exam tests students' knowledge of nurse anesthesia practice.
  • MSN and DNP students take specialized courses in nursing anesthesia, while DNAP programs are already designed around the specialty.

CRNA Certification

Candidates seeking the NBCRNA certification to become a CRNA must pass the National Certification Exam, earn a degree from an accredited CRNA program, hold a current and unencumbered RN license, and provide a statement asserting that they do not have any condition limiting their ability to administer anesthesia.

Recertification requires continuing education credits, completing core modules, and passing an assessment.

CRNA Licensure

CRNA licensing requirements vary among states, but every state requires CRNA certification. Nurse anesthetists apply for licensure with their local state board of nursing. Some states require additional applications for prescriptive authority and/or physician supervision forms. CRNAs must complete continuing education credits to maintain licensure.

Working as a Nurse Anesthetist

Nurse anesthetists are in demand and nurse anesthetists' salaries reflect this. As of 2021, the median annual nurse anesthetist salary approached $195,610. Nurse anesthetists work in a variety of settings, with their responsibilities and scope of practice, including professional autonomy, varying by state.

Hospital Surgical Suites

Nurse anesthetists collaborate with anesthesiologists and the healthcare team, administer anesthesia either under supervision or independently, and manage RNs, surgical technologists, and nursing assistants.

Critical Access Hospitals

Nurse anesthetists provide anesthesia independently depending on the state, work with a healthcare team, and educate patients on postanesthesia pain management.


Ambulatory Surgical Centers

Nurse anesthetists deliver anesthesia independently or in collaboration with anesthesiologists, release patients to go home after procedures, and prepare patients for postanesthesia pain management.

Doctor Office/Pain Management Clinics

Nurse anesthetists educate patients on pain management and provide anesthesia either independently or with supervision.

Nurse Anesthetist Resources

As a professional association of nurse anesthetists, the American Association of Nurse Anesthetists serves more than 53,000 members, including student, certified, and recertified members. AANA's clinical practice resources provide professionals with information and tools relevant to clinical practice, including the nursing code of ethics for CRNAs and information about pain management. The NBCRNA administers the national certification exam that measures the skills, knowledge, and abilities needed to pursue entry-level nurse anesthesia practitioner careers. As the official career center of the AANA, CRNA Careers allows professionals to search for job opportunities. Additionally, professionals can access career resources and learn more about AANA membership.
