Appendix O to the FIA International Sporting Code defines the inspection and licensing process for auto racing circuits intending to host races sanctioned by the Fédération Internationale de l'Automobile (FIA), motorsport's governing body. The grades issued by the FIA are 1, 2, 3, 4 and 6, depending on the suitability of the circuit for different types and groups of cars, with 1 being the highest grade and the only circuits that can host Formula One races. A circuit holding a particular grade can also host events featuring categories of cars at lower grades. The grades are issued "with the sole purpose of permitting the registration of races on the FIA International Calendar, for the categories of vehicles specified".[1]

Grades 1–4 concern various categories of cars depending on their power to weight ratio, and grade 6 relates to autocross, rallycross and ice racing courses. Grade 5 was previously designated for alternative energy vehicles until September 2022 when this was changed to designate developing circuits with FIA Provisional Circuit Licences.[1]
