A rubric is a performance-based assessment tool. Teachers use rubrics to gather data about their students' progress on a particular assignment or skill. Simple rubrics allow students to understand what is required in an assignment, how it will be graded, and how well they are progressing toward proficiency.
Rubrics can be both formative (ongoing) and summative (final) assessment tools for evaluating written work, projects, oral presentations, or any other class assignment. There are four types of rubrics: checklists, holistic rubrics, analytic rubrics, and developmental rubrics. Teachers, including homeschool parents, can refer to these simple rubric examples to formulate their own.
