When it comes to assessing music students, and their learning, I can say with confidence that I am a bona fide expert.
I did this work for thirty years--by my count, evaluating well over 5000 music students, giving them grades and feedback. Which only means I had lots of practice--not necessarily proficiency--but depth of experience matters here. Over three decades, I developed and continuously adjusted a conceptual framework for evaluating the most important skills and knowledge of student musicians, using (and often rejecting) multiple models and metrics. I did it wrong before I did it right. Once I understood that I finally had it right, I kept fine-tuning.
