Music teacher evaluations traditionally examine how teachers develop student music-learning objectives, assess cognitive and performance skills, and direct classroom learning experiences and behavior. A convergence of past and current educational ideas and directives is changing how teachers are evaluated on their use of student-centered instructional approaches in the music classroom. These are classrooms facilitated rather than directed by the teacher in which students regularly communicate, collaborate, self-reflect, problem solve, and peer-evaluate about their learning. The authors trace the influence of three important initiatives that, among others, contributed to the implementation of student-centered learning in music classrooms: Arts PROPEL, Comprehensive Musicianship, and 21st Century Skills. The article also explores relationships between these entities, the National Music Standards, and teacher evaluation and provides an innovative model of teacher evaluation.
