By the fortieth exam essay on My Ántonia, most teachers are grading differently than they were on the fifth. Attention fades, patience shrinks, and the standard shifts without anyone noticing. The student who happened to land in the middle of the pile may get a different score than an identical paper would have received at the start.

This is not a character flaw. It is a predictable feature of human judgment when the same task is repeated many times. The stakes of a final exam make it more important to guard against.

Consistency does not require superhuman focus. It requires a few habits that reduce the room for drift.

The rest of this post covers the ones that tend to matter most.

Anchor yourself before you begin

Before grading, reread your rubric and score two or three sample essays, ideally ones you have already graded in the past. This resets your sense of what each level looks like. Keep those samples nearby and glance at them when you feel your standards moving.

• Shuffle the stack so that no one class or student group is always graded when you are tired
• Grade anonymously by covering names or using student numbers
• Score one criterion at a time across several essays to keep the standard steady
• Take a short break every ten or fifteen essays and reread the top rubric level
• Return to the first few essays at the end and check that scores still feel right

Watch for halo and contrast effects

After reading a brilliant essay, an average one can look weaker than it is. After a series of weak ones, a decent paper can seem outstanding. Being aware of this contrast effect helps, and so does comparing each essay to the rubric rather than to the previous paper.

Similarly, a strong opening paragraph can color the reader's view of everything that follows. Reading the whole essay before assigning any scores helps limit that halo.

Use a second look on borderline cases

Essays that fall near a grade boundary deserve extra attention. Set them aside and return to them after finishing the stack, when you have a clearer sense of the whole range. If time allows, ask a colleague to read a few.

Keep a short note explaining why you settled on the final score, since these are the cases that lead to questions later.

Letting a tool provide a steady baseline

An AI grader does not get tired, which makes it useful as a reference point. GraideMind scores each essay against the same rubric at the same level of attention, and teachers can compare the suggestions to their own. Big differences are a signal to look again, whichever side turns out to be right.

The teacher still owns the final grade, but having a steady second opinion makes it easier to notice when personal drift has crept in.
