Students can use this information as a checklist. I've found that whenever students are provided with criteria, they meet or exceed them. It's very important to eliminate the mystique surrounding evaluation. Students shouldn't have to guess as they prepare an assignment. Examples might include the best writing that was done in a variety of genres of photographs of something that students designed and built.
Children come away knowing what excellence looks like for their particular age and grade level.
