The purpose of this document is to serve as a resource for educators, leaders, districts, professional organizations, teacher education programs, and others. As each set of standards included here emphasizes the skills and knowledge needed for 21st century teaching and learning, they form the basis for teacher preparation, licensure, and professional learning. This document was created to replace "A Vision for Schooling," adopted by the Vermont Standards Board for Professional Educators (VSBPE) in August 2003. The previous "Apple Book" included the Five Standards and Sixteen Principles for Vermont Educators. The new "Tree Book" includes: (1) Core Teaching Standards for Vermont Educators; (2) Core Leadership Standards for Vermont Educators; (3) Professional Learning Standards; and (4) Code of Professional Ethics. This book has been divided into sections devoted to each set of standards. Each section includes an introduction as well as the detailed standards themselves. This allows each section to function alone or in relation to the other standards. Individual sections contain references.
