The 21 CSLA stakeholder webinars took place on September 16, 19, and 20, 2019. During these sessions, the audience was provided an overview of 21 CSLA and asked to provide input on “critical areas” for professional learning for principals and other school leaders. The intended audience for the input sessions were school and district administrators at all levels, county office staff, statewide and local educational agencies and organizations, and other interested stakeholders.
