Описание:

The Common Core State Standards Initiative is a state-led effort initiated by the National Governors Association and the Council of Chief State School Officers to develop language arts and mathematics standards that states voluntarily adopt.

My interpretation: The standards were successfully divided into two categories. The college- and career-readiness standards were developed first and then incorporated into the K-12 standards in the final version of the Common Core we have today. As of August 2015, 42 states, the Department of Defense Education Activity, Washington D.C., Guam, the Northern Mariana Islands and the U.S. Virgin Islands have adopted the CCSS in ELA/literacy and math. They are now in the process of implementing the standards locally.
