In 2013, through its Interstate Teacher Assessment and Support Consortium (InTASC), CCSSO
developed this set of combined resources that both define and support ongoing teacher effectiveness to ensure students reach college- and career-ready standards.
This document includes the InTASC Model Core Teaching Standards: A Resource for State Dialogue, which were released in April 2011, and the InTASC Learning Progressions for Teachers 1.0: A Resource for Ongoing Teacher Development (2013).
