Charters are responsible for observing horse races, calling out race descriptions, and recording data on the race for the purpose of publication. They are usually found at the sidelines of a race track with binoculars that they use to focus on the distance markers along the track. As the race progresses, they call out the horse's numbers, positions, and estimate distances inside the rail and between other horses to another worker.
Additionally, charters maintain the record for horse's names and their drivers, transcribe race results, compute race completion times, and send data to the printer for use in racing publications. They may also revise the order and distance between horses at the finish line if the record is different than that of the official results.
Many charters have a bachelor's degree, but one can qualify for this role with a high school diploma or GED. In addition to formal education, most employers prefer candidates with previous experience working on race tracks, ideally in a similar role. Furthermore, an aspiring charter must have impeccable timing skills, great eyesight, and an aptitude for calculations to perform their duties well.
