Established in 1913 as the Wide Awake School, serving 14 elementary students, the school moved to its present location in 1936 and became the Camino-Placerville Junior Academy, teaching grades K-10. The school later became El Dorado Junior Academy and existed as a K-10 program until 1996 when a decision was made to become a full K-12 school. The school became El Dorado Adventist School, and from 1996–2003, the high school program existed as an extension school of Rio Lindo Adventist Academy in Healdsburg. In the fall of 2003, the North American Division of Seventh-day Adventists gave El Dorado Adventist School the authorization to become a stand-alone, fully functioning K-12 institution, and in June 2004, the school celebrated its first official graduates.
