Oregon Revised Statutes Education and Culture § 336.145

(1) Any district school board may provide for the establishment of classes for adult education. The board may employ personnel for the purpose of establishing and maintaining classes for adults on the fundamental principles of democratic government, English language, citizenship, public affairs, arts and crafts, general cultural subjects, adult recreation and other subjects that the State Board of Education may authorize. The classes shall be conducted in the English language, except as the needs for teaching a foreign language may require otherwise.

(2) The district school board may establish a fee schedule for the classes and collect fees from persons enrolled in the adult education program of the district. The fees shall be used for the support or encouragement of adult education.

(3) The classes shall be subject to the rules of the district school board, shall be organized to meet the needs of the adults in the district and, as far as practicable, shall be held at times and places that are most convenient and accessible to the members of the classes.
