Instructional Materials Matter

Instructional materials can have as large an impact on student outcomes as teacher quality. However, schools, districts, and states lack trusted, transparent information about the quality of the materials and tools they use to guide instruction. Only 37 percent of teachers believe that their district or school's instructional materials are aligned with the CCSS. Current state adoption processes yield inconsistent findings and provide limited evidence to support districts in selecting materials.

Due to the lack of information, selection decisions often privilege factors other than alignment or quality. 90 percent of districts report identifying or developing CCSS-aligned materials as a challenge. In one study, the average cost-effectiveness ratio of switching to higher quality curriculum was almost 40 times that of class-size reduction.
