SCORE International (Southern California Off Road Enthusiasts) is an off-road racing sanctioning body in the sport of desert racing. Founded by Mickey Thompson in 1973, SCORE International was purchased from Sal Fish in late 2012. and is run by its current president and race director Jose A. Grijalva and General Manager Juan Tintos. The sanctioning body's premier series is the SCORE World Desert Championship, which consists of four races in Baja California peninsula: the San Felipe 250, Baja 500, Baja 400, and Baja 1000. Race format Vehicles are released from the start line individually, in gaps of 60 seconds between Trophy Trucks and Class 1 racers then 30 seconds for all other classes. Baja races include motorcycles and quad bikes; which start staging at 5:15am and later released around 6am. Four-wheel vehicles start releasing approximately five hours later at around 11am. Race results are determined by calculating a finish time for each vehicle. The finish time for a vehicle can include time for penalties such as speeding. GPS tracking devices are used to enforce speed regulations and penalties on federal highways and highly congested areas. Awards are given for the winner of each class (if a vehicle in the class finishes) as well as an overall winner across classes, overall four-wheel and overall motorcycle/ATV. Points are awarded based on class finishing position. The racer with the most points at the end of the season is the overall class winner. In the following race season, the vehicle number will end in two zeros "00" to indicate that racer as the class champion. For example, the vehicle number for the Class 1 champion would be No. 100 while the Trophy Truck champion can run No. 1. The starting order is generally determined by a random draw, except when preferential starts are given to those who finished in top positions in the previous race/season, or when qualifying is held. Starting with Roger Norman's purchase of SCORE in 2012, vehicle numbers have become permanently assigned to each driver. Numbers 1–9 are reserved for the prior year's driver standings in those respective positions, while 10–99 are available for assignment. Drivers who have used a number in the prior years season will be given first option for the same number in the current season. SCORE International operates an "Ironman" class for racers that complete a race without any driver change. Commemorative ribbons are given to any
