In Spring of 2007, it was announced that Jeff Dishmon would not be returning as principal of Orange High for the 2007–2008 school year, where he would be moved to a Central Office position.

Hankins was demoted in 2012, and former Gravelly Hill Middle School principal Jason Johnson replaced him.

[6][7] On August 30, 2006, former student 18-year-old Alvaro Rafael Castillo murdered his father, Rafael Castillo, by shooting him seven times in the neck and head,[8] and then drove the family minivan to Orange High School, where he set off a cherry bomb and then opened fire with a 9mm Hi-Point 995 carbine and a sawed-off 12-gauge Mossberg 500 pump-action shotgun.

When his carbine jammed he was apprehended by a deputy sheriff assigned to the school and a retired highway patrol officer who taught driver's education.
