Official Ratings (OR) are one of the many statistics applied to a race card that can be misled in the horse racing world by newcomers.
In horse racing, what are the ratings for?
For the Flat and National Hunt races, the BHA has a ranking system in place that measures a horse based on its past results.
So, if a horse wins, its rating will increase, while a series of bad outcomes will see it fall.
When is a horse going to receive a rating?
When it has won a race or finished in the top six on three different occasions, a horse receives its official ranking. The ratings are used at this level to classify the horse's handicaps for the remainder of its running career.
Every week, the BHA reassesses and adjusts the ratings of horses, so that handicappers can ensure that weights are equally distributed.
