State control over curriculum materials is slowly shifting to districts.
Only 19 states still have laws or regulations that cast them in the role of approving districts’ choices of instructional materials, according to the Association of American Publishers, which tracks textbook-adoption laws and practices.
Just a few years ago, about half the states were “adoption states.” Now that number has slipped, according to Jay Diskey, the executive director of the AAP’s school division. Those states are: Alabama, California, Florida, Georgia, Idaho, Kentucky, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Virginia, and West Virginia.
