The IAU Strategic Plan 2020–2030 identifies five goals to guide the Union’s activities through this decade: to lead the global coordination of professional astronomy, to promote inclusive advancement of astronomy, to promote astronomy as a tool for development, to promote public engagement in astronomy, and, to stimulate using astronomy for primary and secondary education. Education permeates through all these goals – professional development, informal education and formal education for the very young through to the PhD level. For the IAU’s Division C, Education, Outreach and Heritage, the plan provides the foundation for supporting teachers worldwide who use astronomy as a tool for teaching science, the humanities and the arts, to promote astronomy education research, to engage life-long learners, and to engage everyone with our collective history and heritage to understand the Universe. I describe Division C’s remit, where we are now in this 3rd decade of the 21st century.
