Typically, rubrics are set up in a table format and can be looked at through five different components. However, rubrics do not have to be tables - they're often the easiest way to capture the key purpose of a quality rubrics: to enable a learner to self-assess the degree of quality of their work. To that end, a document that lists only one level may be using "rubric" to trigger the reader's perception of a rubric as a self-assessment tool but doesn't fulfill all of the functions of a quality rubric. In other words, when a reader looks at a one-level rubric, they will be unable to identify what they need to do to get better, do better, or improve the quality of their work. This does not mean the tool is not useful or powerful - rather the learner has to infer their degree of quality in relation to the information provided in that one column.  The primary goal of a quality rubric (example) is to provide a learner with a means to self-assess the quality of their work without waiting for an adult's feedback, using indicators of quality that make sense.
