Teacher certification and licensure practices for music educators vary by state. Enhancing music teacher educator knowledge of state music education certification and licensure practices can inform music teacher preparation and improve future music teacher quality. The purpose of this study was to compile relevant information for music educators about the certification practices of each of the United States and the District of Columbia as of January 2016, and to examine the commonalities and differences among the states' policies. Results revealed a movement toward comprehensive certification for all grade levels and music subject areas. Researchers noted heightened accountability through increased testing requirements and the inclusion of teacher performance assessments.
