National Board Certification is a voluntary process by which teachers of students ages 3 through 18 demonstrate accomplished teaching. This article describes the process and certification requirements for one certificate--the Early Childhood/Generalist (ECG), for teachers of children ages 3 through 8. The National Board Certification process was created by the independent, nonprofit, nongovernmental National Board for Professional Teaching Standards (NBPTS) and is guided by five core propositions: (1) Teachers are committed to students and their learning; (2) Teachers know the subjects they teach and how to teach those subjects to students; (3) Teachers are responsible for managing and monitoring student learning; (4) Teachers think systematically about their practice and learn from experience; and (5) Teachers are members of learning communities. These propositions are the foundation of what all teachers should know and be able to do. (Contains 1 resource.)
