Certified Registered Nurse Anesthetist (CRNA)

Nurse anesthetists have roots that go as far back as the 1860s when they administered anesthesia to wounded soldiers during the Civil War. A Certified Registered Nurse Anesthetist (CRNA) has the very important role of providing anesthesia to a patient about to undergo surgery. Certification for the occupation of nurse anesthetist has been a requirement since 1945. To practice as a nurse anesthetist anywhere in the United States, passing the CRNA national examination is compulsory.

In order to be eligible to take the national certification examination and to become a Certified Registered Nurse Anesthetist (CRNA), a candidate must:

  • Have a current and unrestricted license as a professional Registered Nurse (RN).
  • Complete a nurse anesthesia educational program accredited by the Council on Accreditation of
  • Nurse Anesthesia Educational Programs within two years of taking the examination.
  • Submit an examination application form.
  • Submit an official transcript of performance in an accredited nurse anesthesia educational program.
  • Submit a digitalized photo, taken within six months of the examination date, along with a signed authentication of the applicant’s identity form.
  • Never have had a license revoked, restricted, suspended, or limited by any state. The license must never have been surrendered and it cannot be the subject of a pending action or investigation.
  • Not currently suffering from a mental or physical condition that might interfere with the practice of nurse anesthesia.
  • Not currently suffering from drug or alcohol addiction or abuse.
  • Never convicted of or currently under indictment for any felony.
  • Never been the subject of any documented allegations of misconduct, incompetent practice, or unethical behavior.
  • Never been the subject of a disciplinary action, has never been placed on probation, suspended, or dismissed from a nurse anesthesia educational program for unethical behavior, questions of academic integrity, or documented evidence of cheating.
  • Sign a waiver of liability and agreement of authorization, confidentiality, and nondisclosure statement.
