This report seeks to provide context for the current landscape of social studies curricula to highlight the need for high-quality instructional materials (HQIM) in social studies. It serves as a starting point for discussions on identifying HQIM and a guide for the development of social studies curriculum review tools, evidence guides, and training materials for potential use by states and districts. The report examines five main components, including: (1) legislative efforts impacting social studies education; (2) curriculum products; (3) curriculum marketplace; (4) curriculum review tools; and (5) state conditions. The report concludes with a summary of findings and recommendations intended to synthesize key takeaways and considerations for individuals invested in social studies or curricula at various levels to address gaps in HQIM in social studies.
