The Union School District operates six elementary schools (K-5) and two middle schools (6-8) in the greater San Jose, California, USA area.
The district serves 4400 students.
Confusingly, the district is not a union school district under California law; rather, it was named in honor of the Union Army when founded in 1863, during the American Civil War.
Note: Based on 2002-2003 school year data *Alta Vista Elementary is in Los Gatos; all the rest are in San Jose.
For budgetary reasons, the District closed Athenour and Lone Hill schools in 2004, after a local property tax initiative failed to pass.
