The purpose of this study was to describe Illinois music educators' self-perceptions regarding the demographics, logistics, function, and implementation of their classroom operations using the Whole School Effectiveness Guidelines Survey for Music Programs. The survey was administered to K-12 music educators (N = 1,251) throughout the state of Illinois. Participants reported positive self-perceptions in relation to their teaching abilities and leadership qualities, yet were less positive regarding the communication of goals, expectations, vision, mission, and current research with teachers outside of music, administrators, and parents.
