Every grader brings a lifetime of experience to the stack of essays on their desk. When students write about culture, poverty, or belonging, as they often do after reading The Absolutely True Diary of a Part-Time Indian, those experiences can quietly shape scores. Most teachers do not intend bias, but intentions do not remove it.

Research on grading has shown that factors like handwriting, a student's reputation, or even the order in which papers are read can influence scores. Essays on personal and cultural topics add another layer, because a grader may respond more warmly to stories that resemble their own.

The good news is that a few simple habits reduce these effects considerably. None of them require special training, just consistent practice.

Here are strategies that help keep scoring fair.

Grade Without Names When You Can

If your system allows it, hide student names or use ID numbers when scoring. Even small cues can shape expectations. Reading anonymously forces you to respond to the writing itself.

• Score against a written rubric, not an overall impression.
• Grade one criterion at a time across all essays when possible.
• Shuffle the order of papers so early and late essays are not treated differently.
• Take breaks to avoid fatigue, which changes standards over a long session.
• Revisit a few early essays at the end to check whether your standards shifted.

Watch for Style Bias

Students write in many voices, including dialects and registers that differ from formal academic English. A grader may score those essays lower for style even when the ideas are strong. Decide in advance which language features are actually part of your criteria and which are simply differences.

If your standard calls for formal English, teach it explicitly and score it in a separate category. That way it does not quietly influence every other part of the grade.

Be Careful With Emotional Responses

Moving essays can raise scores, and flat ones can lower them, regardless of quality. Check yourself by asking whether a high or low score matches the rubric language. If the answer is unclear, reread with the criteria in front of you.

It also helps to have a colleague review a small sample. A second reader is one of the strongest protections against individual blind spots.

Add Consistency Through Process and Tools

Rubric-based AI grading applies the same criteria to every essay, which can serve as a useful check on human variation. It is not a replacement for professional judgment, and it can carry its own biases, so review results and watch for patterns. Using it alongside your own scoring can highlight where your grades diverge and prompt a closer look.

Fairness in grading is an ongoing practice. Small, repeated habits do more than any single fix, and students notice when the process is steady.
