The PARCC Model Content Frameworks for Mathematics and ELA/Literacy have been developed through a state-led process in collaboration with members of the Common Core State Standards (CCSS) writing teams. The frameworks were reviewed by the public between August 3-31, 2011. Nearly 1,000 responses were collected, and respondents included K-12 educators, principals, superintendents, higher education faculty, school board members, parents and students. In fact, over 77 percent of respondents were teachers, administrators or curriculum directors. While some 200 responses were suggested line-item edits, the vast majority of responses fell into major themes. This paper describes those themes by content area and how the frameworks have been revised to address them. (Contains 2 footnotes.)
