The article analyzes professional development in music education considering the ways in which policy change depends on conditions where renewed practice can become self supporting. The authors situate professional development amid the current politico-educational climate while offering an interpretive framework based on key issues and actions identified by other authors in this issue of "Arts Education Policy Review". Further, they suggest a pragmatic policy agenda focused on the notion of a strategic architecture for professional development in music education, arguing that it may bring (1) greater confidence in teacher's capacity to adapt, engender concepts, intervene in instructional patterns, and establish positive feedback loops; and (2) improvement in teacher retention and productivity. The article calls for a professional development agenda that sees teachers as capable change agents and that is jointly incentivized by union leaders, government, and institutions of higher learning.
