(a) No instructional resource, print or electronic, may be used in any public elementary or secondary school in West Virginia as the primary source to deliver the instructional goals and objectives for state required courses unless it has been approved and listed on the state multiple list by the state board, except as otherwise provided in this section. Any changes of items made by the state board shall become effective upon approval. The state board may upon request by a county board and upon justification of that request, and subsequent to the adoption by a county board approve the adoption of additional items to meet the needs of specific children which were not provided for in the original adoption, or waive the requirement to adopt and use resources in a particular school as provided for in section six, article five-a of this chapter. Nothing in this section shall apply to the supplementary items that are needed from time to time.

(b) The state board may grant permission to county boards for the continued use of previously adopted resources that are listed on the most recently expired multiple list appropriate for the subject category under consideration. The continued use shall not exceed a period as designated by the state board. The state board may make such rules as it may deem necessary and expedient to carry out the provisions of this article.
