Negros Oriental High School

As Silliman Institute did not admit girls until 1912, the Provincial School was the only institution in Negros Oriental where girls could obtain secondary education. Thus, its enrollment representing both sexes rose to 150 in 1904, 249 in 1914, and 479 in 1916. Through the effort of Mr. B. P. Osborn, the Principal, the first Junior Class was organized. Under the efforts of Mr. Spencer Aldrich, the succeeding Principal, the Senior Class was organized in 1919. The faculty members were mostly Americans, with few highly competent Filipinos.
