Athletes performances are timed or measured at virtually all track and field competitions. Doing so can not only serve as a way of determining the winner in an event, but it can also be used for historical comparison (i.e. a record). A large variety of record types exist and men's and women's performances are recorded separately. The foremost types of records organise athlete's performances by the region they represent—beginning with [[national records in athletics|national records]], then continental records, up to the global or [[world record]] level. National governing bodies control the national record lists, the area associations organise their respective continental lists, and the IAAF ratifies world records.

The IAAF ratifies track and field world records if they meet their set criteria. The IAAF first published a world records list in 1914, initially for men's events only. There were 53 recognised records in running, hurdling and relay, and 12 field records. World records in women's events began in 1936 as more events were gradually added to the list, but significant changes were made in the late 1970s. First, all records in imperial measurements were abandoned in 1976, with the sole exceptional being the mile run due to the prestige and history of the event. The following year, all world records in sprint events would only be recognised if [[fully automatic electronic timing]] was used (as opposed to the traditional hand-timing stopwatch method). In 1981, electronic timing was made compulsory for all world record runs in track and field, with times being recorded to within one hundredth of a second. Two additional types of world record were introduced in 1987: world records for indoor competitions, and world records for junior athletes under 20 years old.<ref>[http://www.iaaf.org/mm/Document/AboutIAAF/Publications/05/47/96/20100113075829_httppostedfile_IAAFConstitution-01.11.09-Eng-Website_17812.pdf IAAF Constitution] {{Webarchive|url=https://web.archive.org/web/20100705013805/http://www.iaaf.org/mm/Document/AboutIAAF/Publications/05/47/96/20100113075829_httppostedfile_IAAFConstitution-01.11.09-Eng-Website_17812.pdf|date=5 July 2010}} (pp. 79–80).

The next most important record type are those achieved at a specific competition. For example, the [[List of Olympic records in athletics|Olympic records]] represent the best performances by athletes at the Summer Olympics. All major championships and games have their relevant competition records and a large number of track and field meetings keep a note of their meet records. Other record types include: stadium records, records by age range, records by disability, and records by institution or organisation. Cash bonuses are usually offered to athletes if they break significant records, as doing so can generate greater interest and public attendance in track and field competitions.
