What is the purpose of a rubric in assessing writing?

The purpose of a rubric in assessing writing is to offer clear criteria for evaluating different aspects of student work. Rubrics are designed to break down the assessment process into specific components, such as organization, content, grammar, and style. By outlining these criteria, a rubric enables both teachers and students to understand exactly what is expected for each component of the writing assignment. This clarity helps assessors provide more consistent and objective evaluations, while also giving students a roadmap for improving their writing skills. By using a rubric, the evaluation becomes more transparent, making it easier to identify areas for growth and improvement in student writing. This structured approach ultimately supports the development of critical writing skills in students.
