The American Graded Stakes Committee is a group responsible for classifying horse races in the United States. It evaluates and assigns grades to stakes races, which are important events in thoroughbred racing. The committee aims to maintain high standards and ensure the integrity of these races. The committee's grading system includes three levels: Grade I, Grade II, and Grade III. These grades help horse owners, trainers, and bettors identify the quality and competitiveness of the races. The committee is part of the Thoroughbred Owners and Breeders Association and works closely with various racing organizations.
