Grant Joint Union High School District was a high school district located in northern Sacramento County. It was considered an urban-suburban school district, serving, at its peak, approximately 12,000 students in grades 7 – 12. The district had nine comprehensive school sites—five junior high schools and four high schools.
On November 6, 2007, Measure B was passed by voters to merge the Grant Joint Union High School district with the local elementary school districts, including Rio Linda, North Sacramento and Del Paso Heights. On July 1, 2008, they formed the Twin Rivers Unified School District that now serves about a total of 30,000 students.[1]
