Graded stakes race

European authorities implemented the Pattern race system in 1972 and requested that North America implement a similar method, leading to the development of the graded stakes system by TOBA in 1973. The first list of North American Graded Stakes was published in 1974. The original purpose of grading was to identify the most competitive races, which helps horsemen make comparisons of the relative quality of bloodstock for breeding and sales purposes. However, the advent of the Internet meant that format would eventually be mostly abandoned in favor of G1, G2, G3. Used by TOBA itself, and most significantly by Equibase Company LLC that is the official supplier of racing information and statistics to America's Best Racing, Breeders' Cup, Daily Racing Form, NTRA, The Jockey Club, TRA, TVG, and Xpressbet. A notable exception to the change in format being the three New York Racing Association tracks. Fasig-Tipto began including grading information in 1975, Keeneland Association in 1976, and Daily Racing Form in 1978. In 1998, Canada began to grade Canadian races independently. ==Criteria==

The American Graded Stakes Committee grades only races that: • Have a purse of at least $75,000 for a listed race, $100,000 for Grade III, $200,000 for Grade II, and $300,000 for Grade I. • Have been run for two years under fundamentally the same conditions. For example, the race's distance may be slightly altered, but age and sex conditions may not be. • Restrict entries only by age and sex. For example, a race may be restricted to three-year-old fillies and be eligible for grading, but a race restricted by where a horse is bred is not eligible for grading. • Have preference conditions written to industry standards that seek to give preference to the best horses. • Have post-race drug testing managed by a governmental authority. • Follow rules for androgenic-anabolic steroids and non-steroidal anti-inflammatory drugs, allowing only Boldenone, Nandrolone, Stanozolol, and testosterone. (This is a minimum standard; some racing jurisdictions have even higher restrictions on medications) In 2008, the committee began requiring that toe grabs on the horseshoe, designed to improve traction, be no longer than 2 millimeters. This was in response to studies by Susan Stover showing that such toe grabs substantially increase the risk of catastrophic racing injuries. Recently, racing officials have also banned the use of furosemide (Lasix) in all Black Type races, which include graded and listed stakes races. A newly established race may inherit the graded status of a discontinued race if it is held at the same facility under essentially identical conditions as the discontinued race. For example, the inaugural running of the Pegasus World Cup in January 2017 was Grade I, inheriting the status of the discontinued Donn Handicap. ==Levels==

There are four grade levels, from Listed at the bottom to Grade I at the top. The latter are higher-class races for bigger prizes for horses of the same age group (2, 3 or 3 and up) and may further be restricted by sex. The weight conditions of the races may vary provided they meet the committee's standards to ensure competitiveness. Many grade I races are "weight-for-age", with weights adjusted only according to age and sex, and also there are "set weights" where all horses carry the same weight (usually applicable when all horses are of the same age and sex). Furthermore, there are "conditions" races, in which horses carry weights that are set by conditions, such as having won a certain number of races, or races of a certain value. Finally, some graded stakes are "handicaps", in which an official handicapper assigns weights to each horse in an attempt to equalize the competition. All Grade I races must have a purse of at least $300,000, but not all races with such high purses are Grade I. For example, a racetrack may offer a high purse to attract better fields so the race will be upgraded in future years. The grade level is assigned by looking at data that indicates quality of the field for the last five years. In order to achieve or maintain a Grade I, it is necessary to attract a competitive field over a number of years. For graded turf races, track conditions (normally excessive rain) may sometimes force the race to be run on the main (dirt) track. If this happens, the race is automatically downgraded by one grade level for that running only. The Committee then reviews the race within five days and may restore the original grade. For example, a Grade I turf race that is switched to the dirt will be recorded as a Grade II race, unless the committee feels the quality of the race was sufficient to warrant Grade I. In the United States and Canada, a graded race can be dormant for one year without losing its grade. ==U.S. graded stakes races==
