What is a rubric primarily used for?

A rubric is primarily used for organizing and interpreting observational data by providing a clear set of criteria for evaluating performance across various tasks. It helps educators assess students' work in a structured manner, ensuring consistency and objectivity in grading. A well-defined rubric breaks down the performance into specific components or levels of achievement, assisting both the evaluator and the students in understanding what is expected in terms of quality and performance.

While it can also facilitate self-assessment by giving learners a framework to assess their own work critically, its primary function is to evaluate various forms of student output, making it a versatile tool in both the classroom and training environments. The approach to compiling observational data through a rubric is particularly beneficial in subjects like cosmetology, where practical skills and techniques must be assessed objectively.
