title: Does Mathematical Precision Ensure Valid Grades? What Every Veterinary Medical Educator Should Know.
abstract: Veterinary medical educators use a variety of methods for calculating student grades. Most educators assume grades will be valid as long as the mathematical calculations underpinning each grading method are correct. The purpose of this "teaching tip" is to demonstrate and discuss how mathematical precision does not necessarily equate to truthful scores that accurately reflect what students know or can do. We contend that this topic is of considerable importance to all veterinary educators who assign grades, and to academic deans who make decisions about grading policies.
