Sierra College, a California community college, has its main campus in Rocklin, California, United States. Rocklin is in the foothills of the Sierra Nevada Mountains, approximately 20 minutes from the state capital of Sacramento and 105 miles (169 km) east of San Francisco. The campus lies within the watershed of Secret Ravine, a site of mining operations during the California Gold Rush. In addition to the 300-acre (1.2 km2) Rocklin campus, the District has a 115-acre (0.47 km2) campus in Grass Valley which is in neighboring Nevada County, a campus center in Truckee, and a campus center in Roseville. The Sierra Community College District, a district that covers over 3,200 square miles (8,300 km2), serves Placer, Nevada and parts of El Dorado and Sacramento counties.
Sierra College's origin is unclear. Some say the establishment of the Sierra Normal College and Business Institute in 1882, a small, private college at the location of today's Placer High School in Auburn, California, was later formed into Sierra College. It is commonly thought, however, that Sierra College is the outgrowth of the Placer Union High School District.
The college was officially founded in 1936 and is fully accredited by the Western Association of Schools and Colleges. This is the date that the school uses as the official establishment, even though it had been operating under various names and places before this. It was established as "Placer Junior College". In 1954 the college was named "College of the Sierras" with a wolverine as the mascot. There were other junior colleges named after regions. These included: College of the Redwoods, College of the Sequoias & College of the Siskiyous  The main campus in Rocklin was chosen by 1960, out of 35 possible sites. The planned construction of Interstate 80 was a consideration in the decision making. In 1961, the new campus opened.
It is governed by a board of seven trustees who are elected district-wide and a student trustee. The constituent groups within the district—trustees, faculty, students, management and classified staff—are committed to the principle of shared governance for assuring broad and deep participation in all decisions critical to the college and district. Only five individuals have held the post of president in the last 50 years.
Approximately 125 degree and certificate programs are offered in a wide variety of configurations taught by 216 full and 650 part-time faculty members. Faculty typically has the minimum of a master's degree in their fields and enhance their teaching with research, authorship and industry expertise. Classes are offered both in traditional "on-ground" classrooms and, increasingly, in an online format.
