TCOM’s Dr. Christopher Medina appointed as a National Faculty Chair for C3DO by NBOME

dr. medina headshotThe National Board of Osteopathic Medical Examiners, an independent, nonprofit organization that provides competency assessments for osteopathic medical licensure and related health care professions, has appointed Christopher A. Medina, DO, from UNT Health Fort Worth’s Texas College of Osteopathic Medicine, as a National Faculty Chair for the new Core Competency Capstone exam. Dr. Medina, who is an associate professor with TCOM, is the C3DO Examination Chair effective January 2026 and will serve a term of three years.

“I was definitely surprised, but I was very proud of the opportunity and honored that the NBOME would think of me that way and they would see the work we have done here at TCOM and how it can be a model for the rest of the country,” Medina said.

Since 2020, Medina has served on the NBOME National Faculty and has actively participated in COMLEX Level 1 and Level 2-CE Item Writing and Item Review Workshops. He has served as the physician lead for the C3DO at TCOM since 2023.

The C3DO program is a national initiative by the NBOME to standardize the assessment of fundamental clinical skills for osteopathic medical students, replacing the previous COMLEX-USA Level 2 Performance Evaluation. It is a multi-station Objective Structured Clinical Examination using standardized patients to evaluate history-taking, physical exams, Osteopathic Manipulative Treatment, clinical reasoning, and humanistic skills such as communication, compassion and professionalism. One of the key differences is that the evaluation will be conducted by osteopathic schools themselves, and students can take the examination locally, rather than having to travel to a site for the evaluation.

TCOM has played a leading role in developing the C3DO over the past few years, serving as a pilot site for Phases 2 and 3. The exam will be implemented for the Class of 2029 for schools that apply to NBOME, but it is already a graduation requirement for TCOM students.

“Over the last three years, the exam has shifted in terms of what the number of cases would be for the standard assessment,” Medina said. “We had some schools doing four cases, some doing six, and others doing eight to test the validity of the exam formats, and it was determined that six cases are the best standard assessment.”

The evaluation will be done at the beginning of the fourth-year for osteopathic medical students. As the National Faculty Chair of Examination, Medina will help with osteopathic schools that apply to participate in the C3DO program.

“Right now, there is going to be an onboarding phase where schools apply to participate,” Medina said. “The NBOME wants to have every school participate in this, but they also recognize this will take time for all of the schools to adopt this. Part of my role will be to help schools as they are applying and deciding to participate in C3DO so we can expand the implementation.”

The COMLEX Level 2 PE was postponed during COVID, and since that time, the osteopathic community has been working to revitalize a form of practical assessment skills in students, which is where the C3DO concept was born.

“The C3DO is a six-station standardized patient exam, where the students will have a 14-minute patient encounter followed by a six-minute post-encounter, during which they will complete short-answer and multiple-choice clinical decision-making questions,” Medina said. "They will collect a history, perform a physical exam, and formulate a diagnosis. In three of the six cases, they formulate a plan that incorporates performing Osteopathic Manipulative Treatment. Part of the purpose is to ensure that osteopathic students, as they transition into their roles as physicians, not only have had experience in a clinical setting, but they also have been assessed and have a validation of their competency in terms of data collection, humanistic skills, and osteopathic approach to patients.”

Medina recalls the previous performance evaluation that he himself had to take as an osteopathic medical student. It was a day-long drive from the farthest end of eastern Long Island, New York, to Conshohocken, Pennsylvania, for a nerve-racking day of patient encounters and SOAP (Subjective, Objective, Assessment, and Plan) notes.

“It was difficult, and I remember it was an all-day exam, seeing patients, writing notes, and then driving myself all the way back to the East end of Long Island,” Medina said. “What I would say about this new evaluation, C3DO, is that it’s really going to provide a robust testing experience that will instill confidence in students as they prepare to move into residency training. It will provide an opportunity for them to realize their readiness for residency, and it still keeps in mind convenience and practicality for the students with minimal interruption in their rotation schedule. It will be run by their school to assess the competencies that the school has taught, ensuring students are ready to serve their patients and their community.”
