21st Century Skills
The Partnership for 21st Century Skills has had a strong influence in the development of the Common Core Standards. They describe their mission on their website:
The Partnership for 21st Century Skills is a national organization that advocates for 21st century readiness for every student. As the United States continues to compete in a global economy that demands innovation, P21 and its members provide tools and resources to help the U.S. education system keep up by fusing the 3Rs and 4Cs (Critical thinking and problem solving, Communication, Collaboration, and Creativity and innovation).
P21.org is a great place to learn more about the Partnership and the Framework for 21st Century Learning. There is also an alignment between the Common Core and the 21st Century Skills.
