Lakeland Joint School District involves its teachers in the process of curriculum development and instructional material selection through a curriculum-development system. The district recognizes that the school principal is responsible for the implementation of curriculum in his/her school after board adoption. Therefore, the curriculum-development system for involving teachers is an advisory system. Final adoption of a curriculum and the supporting instructional materials is the responsibility of the Board of Trustees.

The curriculum in the schools of the district may be significantly influenced by programs developed with teachers using the curriculum-development system. Articulated programs in defined subject areas, K-12, based upon curriculum frameworks, are the expected products of the curriculum-development system.
