In joint partnership, Achieve, The Council of Chief State School Officers, and Student Achievement Partners have developed a Toolkit for Evaluating the Alignment of Instructional and Assessment Materials to the Common Core State Standards (CCSS). The Toolkit is a set of interrelated, freely available instruments for evaluating alignment to the CCSS; each tool in the Toolkit supports the expectations in the CCSS and derives from the Publishers' Criteria for the Common Core State Standards. Following an introduction, this report provides: (1) An overview of what is in the toolkit; (2) Tools for evaluating alignment of instructional and assessment materials; and (3) Additional Resources for evaluating Alignment of Instructional Materials. The Publisher's Criteria for the Common Core State Standards is contained in the appendix. [For an expanded version of this report see ED554588.]
