Best Practices for Building 21st Century Skills, K-12
The Partnership for 21st Century Skills has revised and updated Milestones for Improving Learning and Education, the MILE Guide for 21st Century Skills. The new MILE Guide includes:
(1) a visual mapping and self-assessment tool that allows districts to plot where they are today and set a course for future integration of 21st century skills into systems of learning
(2) a set of district-relevant recommendations and promising practices to help local districts move from assessment of 21st century skills integration to concrete action
(3) up-to-date P21 Framework definitions that spell out expectations for 21st century student outcomes and the necessary support systems at the state and local levels.

Also, P21 has released five State Implementation Guides—which offer best practices on building standards, assessments, curriculum and instruction, professional development and learning environments—to help integrate skills (such as critical thinking, problem solving and communication) more purposefully into core academic subjects (mathematics, reading, science, history and others). All of the State Implementation Guides—along with a full library of other 21st century skills resources—are available for free download on the P21 site.
