Licensure standards ensure that the best and most promising candidates receive and retain educator licenses and that the training and professional development they experience contribute meaningfully to this end. These standards also assure that educators have the skills and knowledge needed to support students toward attaining high standards. This publication outlines the Colorado Standards and Approved Program of Professional Education and Professional Development for Teachers and Special Service Personnel, Principals, and Administrators. The knowledge, professional disposition, and performance required in a variety of areas are outlined for each group. For teachers, these areas include: knowledge of content and learning, assessment, democratic ideals, diversity, and communication. For both principals and administrators the areas are setting and modeling standards, leadership, ethics, diversity, personal and professional development, and organization and management. (ND)
