A rubric is a grading table a teacher makes that outlines detailed expectations for an assignment, usually rated from one to four, or as "excellent," "good," "satisfactory" or "needs improvement." A rubric is useful for students because it indicates exactly what the teacher is looking for on an assignment, and what the student can do to receive the highest grade. Teachers usually make rubrics extremely detailed to ensure fairness in evaluating work.
Grading rubrics are useful for teachers because they help give uniform standardized marks for work completed. Rubrics are useful for students because they give them a chance to evaluate themselves as they complete the assignment, and an opportunity to make educated judgments about their own work. Parents can also benefit from rubrics when helping their children with homework because rubrics provide insight into what the teacher is looking for. Rubrics are especially useful to assess performance in project-based learning activities, work habits, oral communication and physical skills.
Some teachers criticize rubrics because they put a great deal of focus on the outcome of an assignment rather than the process of completing it, which may take away from a student's learning. Rubrics help make grading more efficient, but can take away from individualized assessment of a child's progress.
