AZ HB2015

Changes governing board approval of supplemental books in common schools from discretionary ("may") to mandatory ("shall") when courses include basic textbooks with supplemental materials.

Prohibits teachers from using supplemental books until the governing board approves them, rather than allowing use during the school year pending later ratification.

Applies the same mandatory approval requirement to high schools for supplemental books and instructional computer software used alongside basic textbooks.

Requires supplemental books to be approved "before usage" or "before approving" courses, establishing upfront review rather than retroactive approval.

Makes identical changes to the definitions and approval processes in both the common school (15-721) and high school (15-722) textbook statutes.
