Even experienced teachers can be influenced by factors unrelated to the quality of an essay. Handwriting, a student's past performance, or a memorable turn of phrase can nudge scores up or down without the grader realizing it. When many essays on Girl with a Pearl Earring are graded in a short window, these subtle effects can add up.

One of the simplest safeguards is anonymous grading. Asking students to submit work with a number instead of a name, or using a system that hides names until scoring is complete, prevents knowledge of the writer from affecting judgment. Teachers are often surprised by how much a familiar name influences their expectations.

Another safeguard is a detailed rubric applied consistently. When each criterion has observable descriptors, graders are less likely to rely on impressions. The rubric acts as a shared reference that anchors decisions in evidence from the essay.

Watch for Common Biases

Several patterns recur in essay grading. The halo effect occurs when a strong opening leads a grader to rate the rest of the paper more generously, while the order effect causes later essays to be judged against earlier ones. Recognizing these tendencies is the first step toward correcting them.

• Halo effect: a strong introduction inflates the score for the rest of the essay
• Order effect: essays are compared to the ones just read instead of to the rubric
• Fatigue drift: standards shift as the grader tires over a long session
• Style bias: polished prose is rewarded over stronger but plainer arguments
• Expectation bias: known reputations influence how a paper is read

Use Practical Habits to Stay Consistent

Grade in shorter sessions with breaks to limit fatigue, and periodically return to an anchor paper to check that your standards have not shifted. Shuffling the order of essays between sessions can also reduce order effects. These habits take little time but significantly improve consistency.

Another useful technique is scoring each rubric row independently before deciding on a total. Doing so prevents an overall impression from coloring individual criteria. It also makes your reasoning easier to explain when a student asks about a grade.

Consider Language and Background

Essays from students who use non-standard dialects or who are still learning English can be unfairly judged if sentence-level differences distract from the ideas. Keeping content and conventions in separate rubric rows helps prevent this. It ensures that a strong analysis of Griet's position is recognized even when the surface language needs work.

Be mindful of cultural assumptions in prompts and feedback as well. Not every student shares the same knowledge of art, religion, or history, so relevant context should be provided rather than assumed. Fair assessment begins with fair access to the material.

Audit and Use Consistent Tools

Periodically review your grades for patterns that might indicate bias, such as consistently lower scores for certain groups of students. If patterns appear, examine the rubric and your process for possible causes. Sharing anonymized samples with a colleague for a second opinion can offer a helpful outside view.

AI-assisted grading tools apply the same criteria to every essay without fatigue or familiarity, which can serve as a useful consistency check alongside human judgment. Teachers should still review outputs critically and remain responsible for final decisions. Used thoughtfully, the combination can make grading both faster and fairer.
