Learning happens over the course of a lifetime and frequently beyond the classroom. With the support of the MacArthur Foundation, Mozilla has built the Open Badges Infrastructure, which makes it possible for badges issued by different companies and communities to be interoperable and shareable across the web.
People and organizations with content to share align their badges with the open standard, which makes it possible for someone who sees Open Badges to discover the criteria and evidence behind them. Learners around the world are using these portable badges to realize increased learning and professional opportunities.
