If you are looking for a simple but through On-Demand Writing Rubric, this is it! My fifth grade students and I discussed what would make a good on-demand writing piece! The skills on this rubric are what we decided (with a little encouraging of course) would earn students a Proficient or Distinguished rating on State Testing!
This rubric will work for Persuasive, Informative, Narrative, and Descriptive Writing! It can be used with Grades 3-8 as the skills are transferrable!
