Professional standards adopted by the California Commission on Teacher Credentialing in 1997 to guide teacher preparation programs and new teacher assessments. These standards are organized around six interrelated categories of teaching practice: 1) engaging and supporting all students in learning; 2) creating and maintaining effective environments for student learning; 3) understanding and organizing subject matter for student learning; 4) planning instruction and designing learning experiences for all students; 5) assessing student learning; and 6) developing as a professional educator.
