Teachers in most schools are required to provide letter grades—even if they are philosophically opposed to the practice. In Rethinking Letter Grades, the authors offer a practical five-step process for arriving at letter grades that moves away from collecting a string of marks and calculating a grade. They examine a wide variety of assessment tools (rating scales, scoring keys, rubrics, test scores, observation records, discussion notes, symbols, portfolio collections, and more) and match the student evidence with a description of achievement. This description presents a valid picture of student achievement—one that recognizes all aspects of student performance.
