On May 29th, 1946 the voters of Marion Township approved a plan to “reorganize the school facilities of the area into one independent unit”. By 1948, 17 sub districts (including 12 one-room schools, and one two-room school) officially became the Marion Rural Independent School District. At that time, 287 students were enrolled in grades K-8. North 10th Street was lined with farm fields as were most of the other current Linn-Mar school building sites. Despite a district name change in 1959 and three merger votes with Marion Independent — all of which failed — Linn-Mar has had continual growth and retained a sense of community for over six decades.
Today, seven elementary schools, two middle schools and one high school are located throughout the district. More than 1,000 staff serve the educational needs of more than 7,500 students K-12. Whether teaching, busing or cooking, Linn-Mar staff are dedicated to the quality of the educational experience of all students.
