Opened in 1908 as a one-room school, Springlake became an independent district in 1924 when Halsell ranch land was sold to settlers and the local population increased. An enlarged school opened in 1925 in a new $30,000 brick structure on a site bought from J. F. Kelley. E. C. Martin was superintendent, and Otis Brown, M. E. Cleavinger, Earl Hewitt, Arthur Edwards, George Linville, H. M. Packard, and W. C. White were trustees. A band and football squad were organized and a school paper was begun in 1928. Enrollment, curriculum, and the school plant continued to expand. "Earth" was added to the school name in March 1964.
