What is the OSATS?
The Objective Structured Assessment of Technical Skills (OSATS) is an OSCE-like examination in which subjects perform standardized surgical procedures while being evaluated by an expert surgeon. The assessment is made using a task-specific checklist in which all important steps of a procedure are identified and a mark is assigned for every step the candidate completes correctly (0 or 1). Also included is a global assessment score (GAS) which is a 7-item assessment of overall performance such as respect for tissues and flow of procedure. Studies have repeatedly demonstrated the reliability and validity of this assessment tool.
