Complaint Against Teacher for Unfair Grading

When and how to use this letter

Act within the re-evaluation window. Most schools allow only a few days to a couple of weeks after results, so check your school's policy immediately, because a perfect complaint filed too late will be rejected on procedural grounds. Before writing, compare your answers honestly against the marking scheme or textbook. Only proceed if you have genuine reason to believe marks were missed.

Keep the tone respectful toward the teacher throughout. This is the golden rule of grading complaints: frame it as a request for accuracy, never as an accusation of bias. Even if you suspect unfairness, stating it as a concern rather than a fact keeps the principal on your side. Attach a copy of your answer sheet if available, highlighting the specific answers you believe were under-marked.

Request re-evaluation, not punishment. Ask specifically for your paper to be re-checked by another evaluator. This is a standard, face-saving procedure that schools use routinely. The non-obvious tip: phrase your request around your academic record and future, not around the teacher's error. Principals respond to students protecting their future. They resist students attacking their staff.

Accept the outcome whatever it is. Re-checks sometimes raise marks, sometimes confirm them, and occasionally lower them, which is a risk you accept by asking. If the re-evaluation confirms the original marks, take it as feedback and ask the teacher where you lost marks so you can improve. Grace in defeat impresses educators far more than the complaint itself.
