Abstract Competency-based surgical education requires objective, scalable assessment of technical skill, yet existing rating scales are subjective. Objective performance indicators (OPIs) derived from console kinematics, offer a solution; however, they lack a validated scoring framework. We developed and externally validated an OPI-based scoring system from robotic transabdominal preperitoneal inguinal hernia repairs performed by 6 attendings and 41 trainees at an academic center (2023–2026).
