Teachers are human, they make mistakes. But what can you do if you think your grade was a mistake?

Do Your Research

Before approaching your teacher:

  1. 🧠 Know the policy — some school policies say that if you dispute a grade, it can be marked down as well as up. So you could actually get a lower mark. 🤯

  2. 💪 Strengthen your case — review rubrics, course outlines, objectives, and assignment instructions to make sure that it wasn't you who made the mistake.

  3. 👁 Check teacher feedback (if available) to understand why they gave the mark. Teachers will often try to let you know where you went wrong.

3 Main Types Of Grade Disputes

There are many reasons you might want to dispute a mark, but these are the basics:

  1. Scoring Errors

  2. Partial Credit Errors

  3. Subjective Grading or Bad Faith Marks

Each type requires a different dispute strategy.

Scoring Errors

Degree of difficulty: 🔥 (little preparation necessary)

Most of the time, these are a result of overworked teachers having to grade hundreds of assignments quickly.

A woman saying, Wrong Score Recorded:

You had a test with only 2 out of 20 wrong but your teacher gave you a mark of 85%. You know each question had the same value. So, the math is wrong, it should be 90%.

A woman saying, Right Answer Marked Wrong:

You chose answer C and you know it's the right answer but it was marked wrong.

How to handle scoring errors:

  1. 🗣 Describe the mistake clearly with details (question number, assignment info, etc.)

  2. 🙏 Request a change to your mark.

  3. 🤗 Thank the teacher for their time.

Partial Credit Errors

Degree of difficulty: 🔥🔥 (needs some preparation)

You made a mistake but you didn't get it completely wrong and you'd like some additional credit. These types of disputes are a bit more involved. With proper planning, you can convince your teacher to make the change.

How to handle partial credit errors:

  1. Prepare any supporting information (rubrics, notes, slides, etc.).

  2. Acknowledge what you did wrong and appreciate the feedback.

  3. Explain what you did right.

  4. Ask for this to be credited with a partial mark.

Subjective Grading Or Bad Faith Marks

Degree of Difficulty: 🔥🔥🔥🔥 (needs solid preparation)

These are situations where you think your teacher may have been unfair in their marking.  These require careful planning. 

Like most other humans, teachers don’t like to be accused of wrongdoing, hypocrisy, or injustice.  So, don’t do that. 

A teacher in a classroom saying,

How to handle subjective grading or bad faith marks:

  1. Approach the teacher with a clear, calm mind and a reasoned plan. 

  2. Prepare any supporting information (especially rubrics and notes from class).

  3. Be ready to state your case and ask for a grade review.

  4. Be polite, patient, and willing to listen.

Keys To Success

🔑 Have key information ready

  • When was the assignment/test?

  • When was it done/due?

  • What was the question/assignment?

  • What was your score?

  • What was the score you feel you should have?

✅ Talk to the right person

  • In high school or lower, talk to the teacher directly.

  • In college, some assignments may be marked by teaching assistants. Go to them first, then to the professor.

  • Think carefully before you go to the principal or dean. This can make the situation a lot more serious for you and your teacher or professor.

🗣 Use the right words

The words you use can make all the difference. Even when they make mistakes, teachers deserve respect.

❌ Instead of: "You made a mistake!"

✔️ Try: "I think there might be a mistake with my grade, could you please check it with me?"

❌ Instead of: "My grade was so unfair!"

✔️ Try: "I got a lower mark than I feel I deserved."

❌ Instead of: "I want you to check my grade!"

✔️ Try: "I was hoping we could review my mark."


Your friends Pat and Sam both got a better mark than you but it doesn't look like their responses were different than yours. What should you say when you approach your teacher?

A. "Pat and Sam did the same and got a better mark!"

B. "I reviewed the test with some other students and I'm confused about my grade. Can we review it together, please?"

C. "You clearly made a mistake marking my test. You need to fix it!"

D. Any of the above are appropriate.


Which of the responses is best?

In Any Grade Dispute

Flaticon Icon Be appreciative. If the teacher makes the change for you, they may have to go back and change it for everyone.

Flaticon Icon Be understanding. Some types of exams and assignments might have set grading that teachers can't change even if they want to (but don't let that keep you from asking).

Flaticon Icon Be patient. Depending on the assignment/exam, the teacher may need more time to review it and make a decision.
