Rubrics are tools that evaluate student performance based on criteria and define various performance levels. They clarify expectations, promote consistent grading, and reduce subjectivity. Well-designed rubrics also speed up grading and encourage student reflection. When creating a rubric, one should define its purpose, establish criteria based on learning outcomes, choose an appropriate rating scale, and write detailed performance descriptors for each scale point. This ensures rubrics clearly communicate standards and how students can demonstrate their learning.
