NAfME's new standards for music education lend themselves to lots of creative projects and ways to assess student learning in the music classroom. The Model Cornerstone Assessments are NAfME's way to help guide teachers towards best practices and ways to assess that learning and serve as a guide for teachers to create their own. Check out the MCA website to see all the examples:
