Of the several formal programs that engage and serve students in private-independent schools’ middle and upper divisions (e.g., community service learning, athletic teams, clubs, even academic classes), none may exhibit more variability among schools in structure, content, faculty commitment, and avowed institutional importance than the advisory program. Simply put, each advisory program is unique in when, how, how often, and even why advisors encounter and serve advisees and their families; in how much time is given to planning and professional development; and in how much advisory participants value the program itself. While ISM does not provide guidance on some distinguishing programmatic variables (e.g., content of advisory group curricula), we have espoused some core principles and practices. In this article, we express them as a list of attributes to which schools should aspire.
