The list of United States high-school national records in track and field is separated by indoor and outdoor and boys and girls who have set a national record in their respective events.
[1] Since there are no national championships in high-school competition, post-state-championship meets that proclaim such a position are not sanctioned by the NFHS and thus fall only under the T&FN guidelines.
Additionally, high-school competition is conducted under slightly different rules, which have evolved over time.
Some states ran over lower hurdle heights for a period of time.
Invitational meets have offered an assortment of legacy events and an array of relays, which allow each new generation of athlete a legitimate opportunity to compete in all these events, effectively keeping all records relevant and contemporary.
