The ISM is:

The ISM has almost 11,000 members from across the music sector including academics, classroom teachers, instrumental and vocal teachers, performers, composers and songwriters. As a subject association for music, we act as a forum for individual music educators, consultative body and representative of the profession. We are committed to raising educational standards by developing and disseminating high-quality research, professional development and other support focussed on subject knowledge and pedagogy through our sister charity, ISM Trust.

Founded in 2014, the ISM Trust is open to all and focuses on delivering professional development, training and education opportunities to all musicians.
