PA-C stands for “Physician Assistant-Certified,” while PA simply means “Physician Assistant.” The difference comes down to one thing: the “-C” confirms that the person has passed a national certification exam and actively maintains that credential. Every PA graduates from an accredited program, but only those who pass the certifying exam and keep up with ongoing requirements earn the right to add that “-C” after their name.
What the “-C” Actually Means
The National Commission on Certification of Physician Assistants (NCCPA) is the only organization in the United States that certifies PAs. When you see “PA-C” on a provider’s badge or listed in a practice directory, it tells you that person has passed the national certifying exam, completed all continuing education requirements, and holds active certification. The NCCPA describes the PA-C credential as a signal of commitment to evidence-based, equitable, accessible care.
A person listed as just “PA” without the “-C” could be in one of several situations. They may have recently graduated from a PA program but haven’t yet taken the certification exam. They may have let their certification lapse by not completing the required continuing education or recertification exam. Or they may be using the general title informally. In practical terms, the “-C” is the part that matters most for clinical practice, because nearly every state requires active NCCPA certification as a condition of PA license renewal.
How PAs Earn the “-C”
To become eligible for certification, a PA must first graduate from a physician assistant program accredited by the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA). These programs typically take about two to three years and include both classroom instruction and clinical rotations. After graduation, the candidate takes the Physician Assistant National Certifying Exam, known as PANCE.
PANCE is a five-hour exam consisting of 300 questions spread across five blocks. Each block gives you 60 questions and 60 minutes to complete them, with a total of 45 minutes in breaks between blocks. The exam fee is $550, and graduates receive a 180-day window to schedule their test date based on when they graduated and when their application was processed.
There’s a strict limit on attempts. Graduates who finished PA school on or after January 1, 2003, get six years and six attempts to pass PANCE, whichever runs out first. If someone exhausts both without passing, the only path back to eligibility is completing an entire accredited PA program from scratch.
Keeping the Certification Active
Passing PANCE is just the entry point. Maintaining the PA-C credential requires ongoing effort over a 10-year certification cycle, broken into five two-year periods. During each two-year cycle, certified PAs must earn and log at least 100 continuing medical education (CME) credits. At least 50 of those must be Category 1 credits, which come from formally reviewed educational activities. The remaining 50 can be Category 1, Category 2 (less formal learning activities), or a mix. Each two-year cycle also requires a $180 certification maintenance fee.
Beyond CME, PAs must also pass a recertification exam during their 10-year cycle to keep the “-C.” The NCCPA currently offers a longitudinal assessment option called PANRE-LA, which allows PAs to answer questions over time rather than sitting for a single high-stakes exam. Letting certification expire has real consequences. It can affect a PA’s authorization to work, their ability to practice in their state, and their standing with employers and hospitals.
Why the Distinction Matters in Practice
For patients, the PA-C designation is the clearest indicator that your provider meets current national standards. Nearly every state medical board requires active NCCPA certification, a minimum number of continuing education hours, or both as a condition for renewing a PA’s license. Hospitals, insurance companies, and employers also typically require active certification for credentialing and billing purposes. A PA whose certification has lapsed may lose the ability to see patients or bill for services, depending on their state and employer policies.
Anyone can verify a PA’s certification status in real time through the NCCPA’s online portal. The system shows current board certification status and any reportable disciplinary actions issued since 2012. The NCCPA discourages relying on printed certificates or wallet cards for verification, since those documents can become outdated or altered. As of March 2025, all official verification letters include a digital or printed seal for added security.
The “Physician Associate” Title Change
You may have also seen the term “Physician Associate” used in place of “Physician Assistant.” The American Academy of Physician Associates (AAPA) has officially changed its own legal name to reflect this new title, and five state chapters have done the same. However, the title change is far from universal. It requires state-by-state legislative action, and most states haven’t adopted it yet.
During this transition period, PAs are strongly advised to continue using “Physician Assistant” or “PA” as their official title in clinical settings. The AAPA’s legal counsel has warned that using “Physician Associate” before a state formally adopts it could create regulatory problems, disciplinary actions, or malpractice issues. The “-C” designation itself remains unchanged regardless of which title a state uses. Whether someone is called a Physician Assistant or Physician Associate, the PA-C credential still means the same thing: they’ve passed the national exam and maintain active certification through the NCCPA.
