One problem with scoring rubrics is that each level of fulfillment encompasses a wide range of marks. For example, if two students both receive a 'level four' mark on the Ontario system, one might receive an 80% and the other 100%. In addition, a small change in scoring rubric evaluation caused by a small mistake may lead to an unnecessarily large change in numerical grade. Adding further distinctions between levels does not solve the problem, because more distinctions make discrimination even more difficult. Both scoring problems may be alleviated by treating the definitions of levels as typical descriptions of whole products rather than the details of every element in them.
Scoring rubrics may also make marking schemes more complicated for students. Showing one mark may be inaccurate, as receiving a perfect score in one section may not be very significant in the long run if that specific strand is not weighted heavily. Some may also find it difficult to comprehend an assignment having multiple distinct marks, and therefore it is unsuitable for some younger children. In such cases it is better to incorporate the rubrics into conversation with the child than to give a mark on a paper. For example, a child who writes an "egocentric" story (depending too much on ideas not accessible to the reader) might be asked what her best friend thinks of it (suggesting a move in the audience dimension to the "correspondence" level). Thus, when used effectively scoring rubrics help students to improve their weaknesses.
Multidimensional rubrics also allow students to compensate for a lack of ability in one strand by improving another one. For instance, a student who has difficulty with sentence structure may still be able to attain a relatively high mark, if sentence structure is not weighted as heavily as other dimensions such as audience, perspective or time frame.
Another advantage of a scoring rubric is that it clearly shows what criteria must be met for a student to demonstrate quality on a product, process, or performance task.
