Addison Central Supervisory Union In the 2014-2015 academic year, members of the Addison Central community - teachers, administrators, board members, parents, students, and others - engaged in the critical and creative process of developing Addison Central Supervisory Union’s 2015-2020 Strategic Plan (acsdvt.org). That plan tasked us with building “a culture of innovation and continuous improvement that personalizes learning experiences, provides equitable opportunities and results in high learning outcomes and achievement for all students.” One key objective of this goal was to identify or develop a PK-12 educational framework to increase excellence and equity across ACSU’s nine schools. In 2015, ACSU kicked off a 16-month inquiry into the International Baccalaureate (IB) teaching and learning framework.
