The modern day Robla School District started out as the Oak Grove School district organized in the early 1890's and opening on August 11, 1896. There were twelve students. The local resident station and post office were referred to as Robla and therefore caused confusion for residents and potential home buyers as to where the Oak Grove School District was located. To avoid confusion, the District's name was changed to Robla School District on April 14, 1916. Robla is a derivative of the Spanish word "roble" which means "cluster of British Oak trees". In the early 1900's, the Robla area was inundated with many oak trees, and the name was established.
