EZ Grader
Grading stack after stack of assignments is one of the most time-consuming responsibilities in education. In fact, a nationally representative survey by the EdWeek Research Center found that a typical teacher spends approximately 5 hours each week solely on grading and providing feedback on student work. Using an EZ Grader streamlines this task by eliminating manual calculations, allowing educators to instantly convert test scores into percentage grades and letter equivalents.

FAQs
Is this online EZ Grader free for teachers to use?
Yes, this online EZ Grader is 100% free for teachers, professors, tutors, and students. There is no account registration, subscription fee, or software download required.

What is the difference between an EZ Grader and a GPA calculator?
An EZ Grader is designed to score a single test, quiz, or homework assignment based on total questions and missed points. A GPA calculator calculates a cumulative Grade Point Average across multiple courses over an academic term or year.
How does the EZ Grader calculator handle half-points or partial credit?
Unlike old cardboard slide charts, our digital calculator fully supports decimals. You can enter values like 1.5, 2.25, or 3.5 in the wrong answers field to accurately account for partial credit.
Does the EZ Grader automatically round up percentage grades?
The calculator computes exact percentages to two decimal places (e.g., 89.50%). Depending on your school district's policy, you can decide whether to round fractions up to the nearest whole percentage point.
How can I score a test if questions have different point values?
Instead of entering the number of questions, enter the total point value of the test in the "Total Questions" field. Then, enter the total number of points lost in the "Wrong Answers" field.
