A graded stakes race is a thoroughbred horse race in the United States that meets the criteria of the American Graded Stakes Committee of the Thoroughbred Owners and Breeders Association (TOBA). A specific grade level (I, II, III or listed) is then assigned to the race, based on statistical analysis of the quality of the field in previous years, provided the race meets the minimum purse criteria for the grade in question. In Canada, a similar grading system is maintained by the Jockey Club of Canada . Graded stakes races are similar to Group races in Europe but the grading is more dynamic in North America.
