Rubrics can be helpful – both for guiding the development and to the evaluator. A rubric can be used as a checklist, and provide objective measures for scoring.
There are shortcomings of rubrics as well. If they are too general, they don’t provide much guidance. If they are too specific, the rubric can shift the focus to just the specific elements in the criteria, and miss the overall, harder to quantify elements that are important to the overall success and creativity of the work being evaluated.
If appropriate, rubrics may include some way to reward creativity, innovation, excellence and elegance – all of which are difficult to specify and count directly.
