I teach acoustic guitar in middle school. This of course involves students in sixth, seventh, and eighth graders. I am struggling to find new ways to assess all three levels WITHIN their classes in an equitable way. I have many students who take private lessons, and those at every grade level who are just beginning. I'm having difficulty creating new assessments during concert preparations that not only involves each students for grading purposes, but benefits all grade levels, as well as all the performance levels WITHIN the grade levels. For those of you in music education at the secondary level, what strategies do you use outside of regular individual performance assessments?
