The continuing use of low-quality materials in many districts

Curricula and instructional materials are central to academic success. A 2017 literature review of relevant research provided strong evidence that choosing these materials wisely can be a cost-effective lever for states and districts seeking to improve academic achievement. However, many districts in the country have yet to adopt materials that meet the promise of higher, college-ready standards. 

A new Center for American Progress analysis found that 24 of the 26 districts whose curricula are known and rated are using or recommending at least one curriculum with a low rating.

The prevalence of low-quality materials suggests that many districts face financial, process, or capacity barriers to adopting high-quality curricula and instructional materials.
