Which instrument uses explicit criteria to judge quality across multiple dimensions?

• A. Checklist
• B. Rating scale
• C. Portfolio
• D. Rubric

Answer: (D)

A rubric sets out explicit criteria for several aspects of a task and describes what different levels of quality look like in each area. For a project or performance, you might evaluate dimensions such as idea development, organization, evidence, and language use, with descriptors that show what outstanding, good, fair, or needs improvement looks like in each dimension. This clarity helps both the student and the grader: everyone knows exactly what counts as strong work in each part, and scoring is more consistent across different raters.

Compared to a checklist, which usually confirms whether specific items are present or not, a rubric explains how well each aspect is performed. A rating scale often focuses on a single dimension or a general impression rather than multiple components with detailed levels. A portfolio, while valuable for showing growth over time, doesn’t by itself provide the standardized, multi-dimensional criteria used to judge quality in a single assessment. Rubrics combine explicit criteria with multiple dimensions to judge overall quality in a clear, structured way.
