Grading Scale

Before deciding on your own grading scale, please consult with your department or college to see if there is a standardized one. Please see the HUB website for information regarding university grading standards. If you create your own grading scale, please share the grading scale with students via your syllabus and be sure to consistently apply the grading scale to all assignments, including final grades. Student work should be evaluated by the same standards throughout the course of the semester. If there are exceptions or changes to the grading scale, please inform students immediately.

Note: The Eberly Center does not recommend grading on a curve. Rather, we recommend establishing clear and measurable standards for each assignment and maintaining those standards throughout the course. If student work does not appear to match the standards you’ve set, then consider what changes might need to be made to the course(e.g., the difficulty of questions on assessments, better preparation for assessments, etc.).
