This is a 4,3,2,1 scale rubric for art projects. The categories are chosen based on the students own creativity, craftsmanship, use of materials, and completion of the project based on the objectives and curriculum. I have used A,B,C,D,F rubrics and my students get so focused on the letter grade they don't focus on what they can improve on. That's why I have the number scale, it definitely has been a more efficient rubric for my students!
