Rubrics are scoring guides used to evaluate student work. There are two main types of rubrics: holistic and analytic. Holistic rubrics evaluate the overall quality of student work on a scale, while analytic rubrics evaluate different dimensions of work separately. Well-designed rubrics increase the reliability and validity of assessments by clarifying expectations. They also provide students with useful feedback to improve. Teachers should consider the purpose and content of assessments when constructing rubrics to ensure they accurately measure learning objectives.
