The National Commission for Certification of Anesthesiologist Assistants (NCCAA) provides the certification process for anesthesiologist assistants in the United States. The National Commission's charter includes assuring the public that certified anesthesiologist assistants (CAA) meet basic standards related to fund of knowledge and application of that knowledge to the duties of practicing as an anesthesiologist assistant. The certification process for anesthesiologist assistants includes an initial certifying examination, ongoing registration of continuing medical education, and interval examinations for continued demonstration of qualifications.
