Refers to the 1EdTech standard that enables consistent format and exchange of information about learning and education competencies, skills, or academic standards in an open, machine-readable format. The CASE Network was launched by the 1EdTech community to enable all 50 U.S. states to use interoperable academic standards and national learning standards. Through CASE, it is possible to electronically exchange outcomes, skills, and competency definitions so that applications, tools, and platforms can access the data. This enables school districts, schools, and other users in the learn-and-work ecosystem to act upon this data and support instruction accurately. The Network has built a central repository of K-12 state academic standards and competencies frameworks (414), and other national learning standards. These are available in 11 categories: English Language Arts; Math; Science; Social Studies; World Languages; Computer Science; Fine Arts; Health; Physical Education; Career/Tech; Other.
