This file includes a detailed 4-point rubric that assesses three Core Standards:
W.7.2. (Write informative/explanatory texts)
W.7.5. (Develop and strengthen writing)
W.7.9. (Draw evidence from literary or informational texts)
It also includes a goal setting component, for teachers to set with students before writing instruction. There is a space for teacher comments, for you to do while you assess or score the piece, as well as two prompts for students to fill out and reflect on their performance.
Updated to include a correlating Class Report sheet. Please see my 6th and 8th grade versions.
