In the realm of US education, a rubric is a "scoring guide used to evaluate the quality of students' constructed responses" according to James Popham.[1] In simpler terms, it serves as a set of criteria for grading assignments. Typically presented in table format, rubrics contain evaluative criteria, quality definitions for various levels of achievement, and a scoring strategy.[1] They play a dual role for teachers in marking assignments and for students in planning their work.[2]
