Becoming an anesthesiologist assistant takes roughly six to seven years after high school: four years for a bachelor’s degree followed by 24 to 28 months in an accredited master’s program. After graduating, you’ll pass a national certification exam to earn the Certified Anesthesiologist Assistant (CAA) credential. The career pays well, with an average salary around $206,200 per year, but the path requires strong science preparation and clinical training that rivals medical school in intensity.
What Anesthesiologist Assistants Do
Anesthesiologist assistants work under the direct supervision of physician anesthesiologists, functioning as part of a team that delivers anesthesia care before, during, and after surgery. One supervising anesthesiologist typically oversees up to four patients at a time, with CAAs managing the hands-on aspects of each case.
Your day-to-day work includes evaluating patients before surgery, taking health histories, performing physical exams, and ordering lab work like blood draws. During procedures, you administer anesthesia agents, manage airways, adjust anesthesia levels throughout the operation, and monitor patients using advanced equipment like arterial lines and central venous catheters. After surgery, you follow up with patients during recovery, documenting their progress and ensuring continuity of care. It’s a high-responsibility role, but every clinical decision flows through the supervising anesthesiologist’s oversight.
Undergraduate Coursework You’ll Need
CAA programs expect a strong science foundation at the undergraduate level. You don’t need a specific major, but you do need to complete prerequisite courses with solid grades, a B or better is the standard expectation, and pass/fail grading generally isn’t accepted.
Required courses typically include:
- Human or medical physiology (lecture)
- Human anatomy or a two-semester anatomy and physiology sequence with lab
- Physics (lecture)
- General chemistry
- Organic chemistry (at least one semester)
- Biology (college-level, not survey courses)
- Biochemistry
Programs also strongly prefer applicants who have taken statistics, cellular biology, molecular biology, and a second semester of organic chemistry. Survey-level courses like “Survey of Biology,” as well as microbiology, pathophysiology, and animal-based courses, typically don’t count toward prerequisites. If you’re planning your undergraduate schedule, front-load the required sciences and add the preferred courses when you can.
Standardized Test Scores
Most CAA programs accept either the GRE or MCAT, and scores must be from within the last five years. For the GRE, competitive applicants score at or above the 55th percentile in each section with a 4.0 or higher on the writing portion. For the MCAT, the benchmark is a total score of 502 or above with at least 124 in each subsection. These aren’t hard cutoffs at every program, but falling below them puts your application at a disadvantage.
Completing a Master’s Program
CAA training happens at the graduate level, and all programs grant a master’s degree. As of 2024, 17 accredited programs exist in the United States, housed within medical schools or affiliated academic medical centers. Accreditation comes through the Commission on Accreditation of Allied Health Education Programs (CAAHEP), and graduating from an accredited program is mandatory for certification.
Programs run 24 to 28 months and follow a medical school-style structure: classroom and lab instruction in the first year, then heavy clinical rotations. Students typically complete around 600 hours of classroom and laboratory education alongside roughly 2,600 hours of clinical anesthesia training. By graduation, you’ll have personally administered more than 600 anesthetics across a range of surgical specialties. Some of those clinical hours happen at affiliated community hospitals rather than the main academic center, giving you exposure to different practice environments and patient populations.
The curriculum covers pharmacology, physiology, airway management, patient monitoring, and the physics of anesthesia delivery systems. It’s rigorous by design. These programs compress a large volume of clinical knowledge into just over two years.
Passing the Certification Exam
After graduating, you sit for the Certifying Examination administered by the National Commission for Certification of Anesthesiologist Assistants (NCCAA). The exam is offered three times per year through PSI testing centers. You must be at least 21 years old and a graduate of an NCCAA-approved program.
Your eligibility window lasts two years from your graduation date, and you get a maximum of six attempts during that period. Passing earns you the CAA credential, which is what employers and state licensing boards require.
Maintaining Your Certification
Certification isn’t one-and-done. To keep your CAA credential active, you must complete 50 hours of continuing medical education every two years. You’ll also periodically take the Examination for Continued Demonstration of Qualifications (CDQ), which verifies that your clinical knowledge stays current throughout your career.
Where You Can Practice
CAAs are currently authorized to practice in 24 jurisdictions: Alabama, Colorado, the District of Columbia, Florida, Georgia, Indiana, Kansas, Kentucky, Michigan, Missouri, Nevada, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Vermont, Virginia, Washington, and Wisconsin. Some of these states operate under delegatory authority rather than specific CAA licensure statutes, which means the legal framework varies slightly but the scope of practice is similar.
If you have a strong preference for where you want to live and work, check whether that state is on this list before committing to a program. Advocacy efforts continue to expand practice authority to additional states, but the current landscape means your geographic options are more limited than those of nurse anesthetists, who practice in all 50 states.
Salary Expectations
CAAs earn an average of $206,200 per year, or about $99 per hour. The pay range is relatively compressed: those in the bottom 25th percentile still earn around $200,000, while top earners at the 90th percentile make approximately $216,400. This tight range reflects consistent demand and a standardized scope of practice across employers. Most CAAs work in hospital operating rooms, ambulatory surgery centers, or cardiac catheterization labs.
A Realistic Timeline
Here’s what the full path looks like in practice. During your undergraduate years, you’ll spend four years completing a bachelor’s degree with heavy science coursework, gaining clinical exposure through shadowing or healthcare jobs, and preparing for the GRE or MCAT. The application process for CAA programs typically begins in your junior or senior year.
Your master’s program then takes 24 to 28 months, with the first portion focused on didactic coursework and the remainder on supervised clinical rotations where you’re actively delivering anesthesia. After graduation, you schedule your certification exam, which most graduates take within a few months of finishing. From start to finish, expect roughly seven years of education and training before you’re a practicing, board-certified anesthesiologist assistant.
