Like any other evaluation tool, rubrics are useful for certain purposes and not for others. The main purpose of rubrics is to assess performances. For some performances, you observe the student in the process of doing something, like using an electric drill or discussing an issue. For other performances, you observe the product that is the result of the student's work, like a finished bookshelf or a written report. Figure 1.1 lists some common kinds of school performances that can be assessed with rubrics. This list by no means covers every possible school performance. It is just meant to help you think of the types of performances you might assess with rubrics.
