There is a point in every grading marathon where the essays stop registering. You are on paper 58 of 110, and the thesis about Oedipus's pride sounds like the last four. Your comments get shorter, your scores drift, and you know it.

That drift is a familiar problem for anyone who scores large numbers of writing samples. Attention fades, standards shift, and papers late in the stack are often treated differently from papers early on. Students whose papers land late in the pile can pay for it.

Fatigue is not a sign of caring too little. It is a predictable result of doing repetitive cognitive work for long stretches. The solution is not more willpower. It is structure that keeps your judgment steady.

The Oedipus Cycle makes the problem worse than most units. The plot is fixed, the themes are limited, and dozens of students will argue variations on the same point. By the fiftieth essay, originality is hard to spot.

Practical ways to keep standards steady

Small changes to how you grade can protect against drift. Break the work into shorter sessions, vary the order in which you read, and return to your anchor papers at regular intervals. These habits cost little and pay off in consistency.

• Grade in blocks of ten to fifteen essays, with short breaks between them
• Reread an anchor paper every fifteen or twenty essays to reset your sense of the scale
• Shuffle the stack so the same students are not always read at the end
• Score one criterion at a time across several papers when the rubric allows it
• Stop when your comments start repeating without thought, and return later

Make repetition work for you

Since so many students make the same points, build a comment bank. A short set of well-written responses to the most common issues gives students better feedback than tired improvisation would. Adapt each comment with a detail from the essay to keep it personal.

Tracking which comments you use most also tells you what to teach next time. If you give the same note fifty times, it belongs in the lesson. That is one way repetition becomes useful data.

Know when to hand off the first pass

Some of the work is genuinely mechanical: checking whether a thesis is present, whether evidence is cited, and whether the structure holds together. A tool can do a first pass on these without getting tired. It will apply the same standard on the last paper as on the first.

The judgment calls, such as whether an argument is original or whether a reading is persuasive, stay with you. Those are the parts of the job that need a person. They are also the parts that fatigue damages most.
