In 1989, the National Board published What Teachers Should Know and Be Able to Do, a document that articulated the National Board’s Five Core Propositions for Teaching — comparable to medicine’s Hippocratic Oath — setting forth the profession's vision for accomplished teaching. The Five Core Propositions form the foundation and frame the rich amalgam of knowledge, skills, dispositions and beliefs that characterize National Board Certified Teachers (NBCTs).
All National Board Certificates are based on the Five Core Propositions. All NBCTs in all grade levels and subject areas share their commitment and understanding to these Propositions. Therefore, the Five Core Propositions represent what all accomplished teachers share in their expertise and dedication to advance student achievement.
