"Board-certified" is one of those phrases that appears everywhere in healthcare and gets processed by most patients as background noise. It shouldn't be. In anesthesiology, board certification is a specific, demanding, voluntarily pursued credential — and what it actually requires from a physician tells you far more than the two words suggest.

Key Takeaways
- A state medical license permits a physician to practice. Board certification demonstrates that they have been independently tested against the highest specialty-specific standards available.
- ABA board certification requires passing three sequential examinations — the BASIC, ADVANCED, and APPLIED — with the final exam carrying a historical failure rate of 15 to 30 percent.
- Dr. Andrew Hummel is a board-certified anesthesiologist and Diplomate of the ABA. His status can be independently confirmed through the ABA's public physician directory at theaba.org.
- Board certification is not a one-time achievement. Ongoing MOCA requirements keep board-certified anesthesiologists current with evolving clinical standards throughout their careers.
Before you go under general anesthesia, you want to know that the person managing your airway has been tested — not just trained. Training tells you that someone completed a program. A board certification tells you they were then evaluated, independently and rigorously, against the highest standard in their specialty. Those are not the same thing, and the difference matters when you are the one on the table.
Dr. Andrew Hummel, a board-certified anesthesiologist practicing in Missouri, holds the ABA Diplomate credential. Understanding what it actually took to earn it is the fastest way to understand what it means.
A License Lets You Practice. Certification Proves You've Mastered It.
Every physician in the United States needs a state medical license to practice. That license is the legal floor — it confirms that a physician passed the required licensing examinations and met their state's basic criteria. What it cannot tell you is how deeply they know their specialty, how they perform under pressure, or whether they have been evaluated by anyone outside their own training program after residency ended.
Board certification fills that gap. It is not required by law, which is precisely what makes it meaningful — it is something physicians pursue voluntarily, knowing it demands significant additional effort and carries the real possibility of failure.
In anesthesiology, the body that administers this credential is the American Board of Anesthesiology, one of 24 member boards of the American Board of Medical Specialties. When you see "Diplomate of the ABA" on a physician's profile, you are looking at someone who cleared a bar that the law does not require them to clear.
Three Exams. One Standard. No Shortcuts.
ABA board certification requires passing three examinations, each building on the last.
| Exam | What It Tests | When It Is Taken |
|---|---|---|
| BASIC | Core science foundations — pharmacology, physiology, anatomy, and the reasoning behind clinical decisions | After the first year of residency |
| ADVANCED | Clinical anesthesiology across all major subspecialties, including cardiac, pediatric, obstetric, and regional anesthesia | After residency completion |
| APPLIED | Complex clinical decision-making under examination pressure, including a Standardized Oral Examination | After residency; taken after passing BASIC and ADVANCED |
Table 1: The Three Stages of Anesthesiology Board Certification
The APPLIED exam is the one that catches people out. Its Standardized Oral Examination is two 35-minute sessions with trained examiners presenting high-acuity clinical scenarios that demand immediate, structured responses. There is no time to hedge. You are expected to think the way you would think in an actual operating room, because that is exactly the situation that the exam is designed to simulate. The historical failure rate sits between 15 and 30 percent — which means between one in seven and nearly one in three candidates who sit it do not pass.
Dr. Andrew Hummel passed all three. He also goes further: he serves as a mock oral board examiner at JustOralBoards.com, helping residents prepare for the APPLIED exam through realistic simulations drawn from actual clinical cases. You cannot effectively teach someone to navigate that kind of pressure unless you have faced it yourself — under real conditions, with real consequences.
The Credential Does Not End at Certification
One thing that makes ABA board certification meaningfully different from a diploma on a wall is that it does not simply sit there after it is earned. The ABA's Maintenance of Certification in Anesthesiology program — known as MOCA — requires ongoing professional development, periodic assessment, and continuous engagement with clinical standards that evolve as medicine advances.
This matters more than it might initially seem. Anesthesiology changes, and guidelines are updated as new evidence arrives. New agents, techniques, and technologies enter practice. What was standard a decade ago may have since been refined, replaced, or reversed. A board-certified anesthesiologist under MOCA requirements is not resting on a credential they earned years ago — they are actively maintaining the competence that credential represents.
Two More Certifications Worth Knowing About
Beyond his ABA Diplomate status, Dr. Hummel holds dual certification in Advanced Cardiovascular Life Support and Pediatric Advanced Life Support. These are emergency response competencies with direct clinical relevance to anesthesia practice:
- Advanced Cardiovascular Life Support — or ACLS — covers adult cardiac emergency management — arrhythmia recognition, resuscitation protocols, and post-cardiac arrest stabilization.
- Pediatric Advanced Life Support — or PALS — extends those competencies to pediatric patients, where the physiological parameters, drug dosing calculations, and response protocols are meaningfully different from adults.
For a physician whose practice spans young children, laboring mothers, high-acuity elderly patients, and complex orthopedic cases, these are not supplementary credentials. They reflect the clinical breadth that a genuinely perioperative practice actually requires.
You Can Verify This Yourself
You do not have to take anyone's word for it. The ABA maintains a public physician directory at theaba.org — free to use, no account required — where anyone can search by name and confirm a physician's current Diplomate status directly. It takes under a minute and gives you a primary-source confirmation that sits entirely independent of any third-party profile or physician-managed website.
That is a rare thing in healthcare: a credential you can check yourself, in the time it takes to pour a cup of coffee, from a source that has no stake in the answer.
