In 1914, Red River Lumber Company opened a private high school, that even included night courses for the benefit of the employees. In the fall of 1916, the high school was converted into a public one with an enrollment of forty students. Initially, the grammar and high school shared the same building, but with increasing enrollments it was determined the high school have a building of its own. In the fall of 1918, a new two-story high school was built adjacent to the grammar school. Dedication of the new high school did not occur until March 8, 1919. Red River paid for the construction of the high school, which normally residents of the school district would have passed a bond measure to do so. However, the State of California paid the teacher’s salaries.
