Castana is within the Maple Valley–Anthon–Oto Community School District.

The community was originally a part of the Castana Consolidated Independent School District. The lower level of a building constructed in 1888 was the first classroom area. In 1897 a permanent $12,000, three story Castana Normal School building opened. An addition was completed in Summer 1911. The school district acquired a teacher's residence hall in 1920; that building also housed classes for several grades.

In 1935 and 1936 the Castana Consolidated School, the final school building in Castana, was built by the Sioux City company Beuttler & Arnold, funded by a $36,818 Public Works Administration grant and a $45,000 bond. It opened for classes on September 7, 1936. In November of that year the school district sold the previous school to the city government for $1,000, and the building was razed. The 1935–1936 school was renamed the Castana Community School in 1954.

The district began sending high school students to the Maple Valley Community School District in Mapleton and to Onawa in fall 1962. Castana joined the Maple Valley district along with Danbury in 1968. The merged district did not use the teacher's residence and sold it in 1970. On July 1, 2012, the Maple Valley district consolidated with the Anthon–Oto Community School District to form the new Maple Valley–Anthon–Oto district.
