Rubrics, of course, are assessment tools, and they are used by teachers to grade or assess student work in an analytical way. What this means is that they divide the grading process into different parts, each of which represents an expectation for the assignment. By using rubrics, instructors can more precisely assess student achievement on an assignment. They can help save time, reduce the amount of feedback teachers have to write, clarify what students need to do better (and what they are doing well), and help teachers grade subjective assignments in a more objective, and more uniform way. There are far too many different types of rubric to describe in this space, but they are fundamental to modern assessment.
