In 1949, 17 rural schools joined to build the Marion Rural Independent School District. At that time, 287 students were enrolled in grades K-8. Tenth 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.
In the future, Linn-Mar is planning for additional schools. The school board recently approved a restructuring plan that would transform the Elementary Schools to PK/K-4th grade, the middle schools to 5th-7th grade, create an 8th-9th grade center and transform the high school to 10th-12th grades. This would require community approval through a bond vote in 201 and the school district to build a new middle school.
