History. The Common Core State Standards (also known as CCSS) was a joint effort by the National Governors’ Association Center for Best Practices (NGA Center) www.nga.org and the Council of Chief State School Officers (CCSSO) www.ccsso.org in partnership with Achieve, ACT, and the College Board.
The Common Core State Standards for English Language Arts & Literacy in History/Social Studies, Science, and Technical Subjects (“the Standards”) are the culmination of an extended, broad-based effort to fulfill the charge issued by the states to create the next generation of K–12 standards in order to help ensure that all students are college and career ready in literacy no later than the end of high school.
