The Music Progress Mark Rubric is a rubric to assess a student's progress, and includes room for comments, and a guardian's signature.
As a planning time teacher, keeping students' guardians up to date proves to be difficulty. Using this rubric, you can quickly highlight the overall level the student is achieving in planning and processing skills (based off use of feedback, making revisions, asking questions, etc.), as well as overall knowledge and understanding skills. The rubric also works just as well for classroom teachers.
