In my class, we brainstorm and write the rough draft, then switch with a partner and have the partner edit the paper. I've found that having the editor use this rubric has helped a lot. This rubric has a spot for the editor to assess the following: brainstorm, intro paragraph, concluding paragraph, indentions, at least 3 body paragraphs, formal tone (no text-speak or slang), 3rd person writing, grammar and punctuation mistakes, complete sentences, and staying on topic. There is also a portion at the bottom for students to write comments...I encourage positive ones. I've included two rubrics per sheet, so when I print them out, I just cut them in half and pass them out.
