The Twin Ridges Elementary School District is located in the Sierra Nevada Foothills of Nevada County midway between Sacramento, California and Reno, Nevada. The area is rural and is the setting for a number of small communities that are widely dispersed.
The population is a mix of alternative and traditional life styles. Geographically, the District is the largest in Nevada County though it has the smallest student population. The District has its roots in the one-room schoolhouses of the California gold rush era. One of these historic buildings is still in use by the District today.
During the early 1970’s, the Twin Ridges Elementary School District formed through the merger of two small, rural school districts whose own histories stretched back to the 19th century.
Currently, there are two small schools in the District: Washington School, on the South Fork of the Yuba River, and Grizzly Hill School, on the San Juan Ridge.
