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. 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. The toolkit was originally released in July 2013 and updated in August 2014. The Publishers Criteria for the Common Core State Standards is appended.
