White Oak School began on land purchased in 1892 from John Jordan for one dollar. The present schoolhouse, built in the 1920s, is a one-room wooden building with a tin roof. Its earliest furnishings were simple tables and benches made by the school trustees.

The school usually had one teacher for grades one through seven, with eighth grade added later. Teachers were expected to speak both English and German. The first teacher was A. D. Fischer, who earned $30 per month. Families helped support the school through an annual fee of $8 and a monthly charge for each pupil.

Until a cistern was installed at the second school, two students carried water from a neighboring farm, and all pupils drank from the same tin cup. Students brought lunches from home, often including homemade bread, boiled eggs, butter, jelly bread, and sausage.

Daily chores were part of school life. During recess, students and the teacher pulled broom weeds and tidied the grounds. Each afternoon, pupils swept the schoolhouse, cleaned blackboards, and dusted erasers. When time allowed, they played games, and in later years, White Oak students played baseball against neighboring schools such as Tivydale, Wrede, and Morris Ranch.

On August 14, 1950, White Oak School consolidated with Morris Ranch School, which later became part of the Fredericksburg Independent School District. In 1990, the Charles Feller family donated the schoolhouse and outbuildings, and they were moved to the Pioneer Museum Complex in Fredericksburg.
