What requirements are needed to be a nurse anesthetist?

"The requirements for becoming a Certified Registered Nurse Anesthetist (CRNA) mainly include having a bachelor's degree in nursing, Registered Nurse licensure, a minimum of 1 year acute care experience (ICU, ER for example), and the successful completion of both an accredited nurse anesthesia educational program and the certification examination."

In 1980 the American Association of Nurse Anesthetists mandated that all applicants to nurse anesthetist programs must have a minimum of a Bachelor of Science (but not necessarily a bachelor's degree in nursing)-a requirement that took effect in July 1987. Nurse must gain at least one year of practice experience before entering an accredited nurse anesthesia training program. Following completion of a 2 to 3 year program they are required to pass a national certification examination.
