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.
The dream of creating a new district to serve the students in the territory north of the American River began in 1931, when voters approved plans for the district with an overwhelming 750-25 vote. A bond, promoted through door-to-door canvassing by a citizen named William Rutherford, was passed by the taxpayers and the Grant Joint Union High School District was formed. The first classes were held in the Hotel North Sacramento at the corner of Del Paso Boulevard and Arden.
The enduring "can-do" spirit of Grant District and North Area neighborhoods has created educational programs, facilities and community resources that have continued to serve students families and communities, from building an Olympic-size community swimming pool in 1934, to starting the nation's first school-run radio program in 1940, to establishing a resident school for Aeronautical Training (Grant Tech), which later became American River College.
