The Tri-M® Music Honor Society is an international program dedicated to the recognition of exceptional music students in grades 9 through 12 that meet the musical, academic, leadership, and character criteria asked of every Tri-M member. Tri-M is a program of MENC: The National Association for Music Education, which is the largest arts education association in the world. Once achieving Tri-M membership, each student is expected to continue to meet the Tri-M criteria, or membership will lapse until those standards are once again met. Each member is instructed in the aims, purposes, and programs of the honor society.
