I love using this rubric to have students self-assess! We have moved to a standards based report card in my district and I use this to help teach students about the 1-4 grading system. For the final blank box I have my students decide as a class what they should be graded on, and depending on the class this can change. We fill this category out together but you could also have students decide on their own! I have my students glue this to the back of their projects and fill it out at the end. If you like this I also have 1st, 2nd, 3rd, and 5th grade assessments as well!
