As a senior, Carr led the Eagles football team to a 12–1 record and the California Interscholastic Federation Central Section Division V championship; the only blemish came at home against Oaks Christian High School, a national football powerhouse, during the team's season opener. On October 29, 2008, Carr was selected by ESPN RISE as the National Football Player of the Week after passing for 441 yards and three touchdowns in a game against Tehachapi High School five days earlier. Carr would eventually set a Central Section record by throwing 544 yards in a win against Arvin High School on November 7, 2008. Carr was also selected by The Bakersfield Californian as the 2008 All-Area Football Player of the Year. Carr also set a new school record when he passed for six touchdowns and ran for two in a blowout win against small school Fowler High at home. After his high school football career finished, Carr was named the National Player of the Year by the National Private Schools Athletic Association in 2009.
