Mission-based advisory is the front line of guidance and the center of a school’s leadership programs. It accomplishes those objectives through the recruitment of faculty who see advisory as a crucial element of their teaching practice, whether in middle or upper schools.1 Teaching, to these faculty, is holistic and encompasses the wider framing of a student’s success or failure. For optimal success, each student must experience a predictable and supportive environment in which at least one teacher truly knows and appreciates him/her, can act as an advocate in both good and bad situations, and is a crucial communications link between the school and the parent.
