ABIM, the LKA, and AI: How Data Forensics Are Driving Exam Invalidation

The American Board of Internal Medicine (ABIM) has recently issued a public announcement addressing content-sharing and professionalism obligations related to its Longitudinal Knowledge Assessment (LKA®). Although framed as a general reminder, the announcement follows ABIM’s determination that the LKA results of certain physicians are “unreliable” based on statistical analysis and data forensics—and its decision to invalidate those results.
At the same time, some diplomates have received confidential, individualized notices informing them that their Internal Medicine LKA results have been invalidated and that they will be required to pass the traditional, proctored 10-year Maintenance of Certification (MOC) examination to satisfy their assessment requirement. These communications make clear that ABIM’s actions are not theoretical or prospective; they are already underway, with real and potentially serious consequences for affected physicians.
Why ABIM Issued This Announcement Now
ABIM states that it uses statistical analysis and data forensics to detect patterns suggesting prior knowledge of questions or content-sharing. While ABIM does not publicly detail its methodologies, the timing and substance of this announcement strongly suggest that a precipitating factor was the widespread use of large language models (LLMs) by some examinees.
Specifically, we are seeing increased enforcement activity tied to physicians who allegedly copied and pasted full or partial LKA questions into AI tools—either during or after answering questions—in order to generate explanations or confirm answers. ABIM has made clear that this conduct is prohibited, regardless of intent.
Even where examinees did not believe they were “cheating,” ABIM takes the position that importing assessment content into external tools undermines the validity of the exam and violates the non-disclosure agreement signed by all LKA participants.
Importantly, ABIM’s policies do not require proof of intent to gain an unfair advantage. From ABIM’s perspective, the only relevant question is whether the resulting data patterns render the assessment results unreliable.
What the Targeted Email Looks Like
Physicians whose LKA results have already been invalidated have received confidential emails informing them that:
-
ABIM has identified anomalous response patterns across multiple LKA quarters
-
The results of their LKA are deemed unreliable
-
Their LKA participation has been invalidated
-
They are required to pass the traditional, proctored 10-year MOC examination to satisfy the assessment requirement
-
Failure to pass the proctored exam by a stated deadline will result in a lapse of certification
These notices typically cite ABIM’s “Evaluations and Judgments” provisions and emphasize that ABIM alone determines whether exam results are reliable—even where unreliability is found “through no fault of the candidate.”
What an LKA Invalidation Does — and Does Not — Mean
While an ABIM determination that LKA results are “unreliable” cannot be appealed, it is critical to understand what this decision does not do.
Physicians whose LKA results have been invalidated remain ABIM certified, provided they are otherwise meeting their Maintenance of Certification (MOC) requirements. ABIM has expressly stated that affected diplomates will continue to be reported as certified during the period in which they are given the opportunity to complete the traditional, proctored 10-year MOC examination.
In other words, an LKA invalidation does not immediately jeopardize certification, and physicians may continue to hold themselves out to hospitals, employers, payors, and the public as ABIM Board Certified.
ABIM has also provided a significant accommodation: affected physicians are given additional time—through December 31, 2027—to pass the traditional MOC examination. Only if the proctored exam is not passed by that deadline would certification lapse.
A Cautionary Note
That said, diplomates should be aware that ABIM distinguishes between invalidated assessment results and alleged misconduct. While an invalidation notice alone does not necessarily accuse a physician of wrongdoing, ABIM’s policies permit further action where it believes examination ethics or non-disclosure rules were violated.
If you receive any subsequent communication from ABIM alleging improper conduct or policy violations, you should take that notice seriously and proceed carefully.
Our firm regularly represents physicians in credentialing and examination-related matters involving ABIM and other testing authorities. If you have received an ABIM notice concerning your LKA participation or are unsure how to interpret a communication you have received, we encourage you to contact our office to discuss your situation confidentially.
