CRNA and CAA: Two Paths Into Anesthesia

Certified Registered Nurse Anesthetists (CRNAs) and Certified Anesthesiologist Assistants (CAAs) both administer anesthesia as part of the anesthesia care team. They get there by different educational routes. Which path fits you depends mostly on your background, your timeline, and where you want to practice.

Side-by-side comparison

	CRNA Certified Registered Nurse Anesthetist	CAA Certified Anesthesiologist Assistant
Entry background	Registered nurse (BSN)	Any bachelor’s degree that includes the science prerequisites
Prior clinical experience	Critical care (ICU) RN experience, typically 1+ year	Patient-care experience and anesthesia shadowing (varies by program)
Admissions test	GRE at some programs	GRE or MCAT at most programs; a few are test-optional
Degree earned	Doctorate (DNP or DNAP)	Master’s (MSA / MHSA / MMSc)
Program length	~36 months	~24–28 months
Typical total time	~7–10 years from starting nursing school	~6 years from starting undergrad
Accrediting body	COA	CAAHEP (via the ARC-AA)
Certifying exam	National Certification Exam (NBCRNA)	Certifying examination (NCCAA)
Application service	NursingCAS (or direct to program)	CASAA
Accredited programs (approx.)	~130	~30
Where licensed	All 50 states	A more limited — and changing — set of states and jurisdictions

Which path fits your background?

• You’re already an RN with ICU experience. The CRNA path builds directly on that experience.
• You have (or are working toward) a bachelor’s degree in any major, and you’re not a nurse. The CAA path is designed for exactly that starting point.
• Where you practice matters a lot to you. Check current licensure for both credentials in the states you’re considering before you commit to a path.

A note on scope of practice

Scope of practice, supervision requirements, and licensure are set by state law and change over time. Rather than summarize rules that vary by state and may be out of date, we recommend checking current requirements directly with the state board and the relevant certifying body for the states you’re considering.

Compensation

Both are well-compensated careers. Actual compensation varies meaningfully by region, practice setting, and experience.

Where we stand

We build preparation tools for both paths, and we don’t think one credential is better than the other. The best path is the one that fits your background, your timeline, and where you want to practice.

Program counts, timelines, and requirements change. Verify details with each program and with the accrediting and certifying bodies before making decisions.
