How is the ABOS Part II scored?

The ABOS Part II oral exam is scored using a standardized rubric with 9 distinct dimensions. Each dimension is scored on a 0 to 3 scale by both examiners independently. A score of 0 means the candidate demonstrated no competence in that area, while a 3 reflects the performance expected of a well-trained, board-eligible orthopedic surgeon. The scores from all sessions are aggregated to determine the final pass/fail outcome.

The 9 scoring dimensions cover the full spectrum of clinical reasoning: data gathering, diagnosis, applied anatomy, surgical indications, treatment planning, technical skill description, complication management, outcomes assessment, and applied basic science. Importantly, each dimension carries equal weight. Candidates often assume that surgical technique is weighted most heavily, but a weak score in data gathering or complication management can fail you just as easily.

What trips candidates up is not a lack of knowledge — it is presentation. The rubric rewards organized, concise, confident answers. When you volunteer extra details, you create openings for examiner follow-up on tangential topics. When you hedge or contradict yourself, even correct answers score lower. Practicing under realistic conditions — where someone challenges your reasoning in real time — is the most effective way to improve rubric performance. Ortho Board Prep's mock oral sessions are designed specifically around these 9 dimensions.
