Visual Reference Images

Visual Reference Images (VRI) are used to ensure consistent and uniform application of grading interpretations. The visual grading aids system represents the foundation for the national inspection system’s subjective quality control program, providing an effective management tool for aligning inspectors and assisting them in making proper and consistent subjective grading decisions. This system consists of Interpretive Line Prints (ILP), General Appearance Prints (GAP), and Other VRI.
