In January 2011, the NYS Board of Regents adopted the NYS P-12 CCLS, which include the Common Core State Standards and a small amount of additional standards uniquely added by New YorkState. The New York State P-12 CCLS were implemented in New York State schools at the beginning of the 2012-2013 school year.
Illinois started to adopt the Common Core standards in 2010, and fully implemented them last school year. Next spring, the PARCC tests linked to Common Core standards will be used in school districts across the state.
