The Common Core is a set of high quality academic standards in mathematics and English language arts (ELA).
In 2009 the state school chiefs and governors that comprise CCSSO and the NGA Center coordinated a state-led effort to develop the Common Core State Standards. Designed through collaboration among teachers, school chiefs, administrators, and other experts, the standards provide a clear and consistent framework for educators.
The standards were created to ensure that all students graduate from high school with the skills and knowledge necessary to succeed in college, career, and life, regardless of where they live. The standards define the knowledge and skills students should gain throughout their K-12 education in order to graduate high school prepared to succeed in entry-level careers, introductory academic college courses, and workforce training programs.
Forty-two states, the District of Columbia, four territories, have voluntarily adopted and are moving forward with the Common Core.
