The numbers keep getting worse. Recent research shows that teachers in the United States spend an average of 9.9 hours per week on grading alone, more than a full working day. Ninety-five percent of them take grading work home. A third have seriously considered leaving the profession in the past year, and the primary reason is not salary, student behavior, or lack of administrative support. It is the sheer volume of grading. For teachers in writing-heavy subjects like English, history, and social studies, this burden falls hardest, because essay grading is the most time-intensive form of assessment that exists in K-12 and higher education.

A peer-reviewed workload review published earlier this year confirmed what classroom teachers have been saying for a long time: marking and lesson preparation are consistently reported as the largest contributors to unsustainable workload. In England, teachers spend over 50 hours per week working on average, compared to a standard 37.5-hour week. In the U.S., the picture is similar. Nearly half of all teachers report frequent burnout, with rates climbing year over year. The data is no longer ambiguous. The grading workload problem is structural, and it is driving experienced educators out of the profession.

What makes this especially concerning for writing-heavy classrooms is that essay grading cannot be skipped or simplified the way other assessment types can. A multiple-choice quiz can be auto-scored in seconds. A short-answer prompt can be evaluated quickly. But a five-paragraph essay, a DBQ response, or a research paper requires sustained attention, interpretive judgment, and individualized feedback. Teachers who assign the kind of writing that develops critical thinking are penalized with the heaviest grading loads, which creates a perverse incentive to assign less writing.

Survey data from the current back-to-school season adds texture to these numbers. Among nearly 7,500 educators polled ahead of the 2026-27 school year, about 30 percent reported high or critical workload-related stress. At the same time, 83 percent said they have used AI tools for school-related tasks, with reducing administrative workload ranking among the top three use cases. Teachers are not waiting for permission to seek relief. They are actively looking for tools that lighten the load.

Where the Time Actually Goes in Essay Grading

Breaking down the essay grading process reveals why it consumes so much time. The bottleneck is not reading the essay. It is the cognitive work of evaluating it against multiple rubric dimensions, formulating specific feedback, and recording scores in a gradebook. Each of those steps involves context switching, and when multiplied across 100 or 150 student submissions, the cumulative effect is enormous. Teachers who grade essays report that the first 20 papers take the longest, because they are calibrating their rubric application. Papers 21 through 80 go faster but are mentally exhausting. The final batch often suffers from grader fatigue, with scores drifting and feedback becoming thinner.

• Reading a single student essay typically takes 3 to 5 minutes, depending on length and complexity.
• Applying an analytic rubric across 4 to 6 dimensions adds another 2 to 4 minutes per paper.
• Writing individualized feedback comments adds 3 to 7 minutes per paper, depending on the teacher's standards.
• Entering scores into the gradebook and syncing with the LMS adds additional overhead, especially when systems are not integrated.
• Across a set of 120 essays, total grading time can easily reach 20 to 30 hours, spread across evenings and weekends.

Why Traditional Workload Remedies Fall Short

Schools have tried various approaches to the workload problem: hiring additional staff, offering stipends for grading-heavy assignments, reducing class sizes, and providing professional development on time management. Each of these addresses a symptom rather than the root cause. Hiring is limited by budgets and shortages. Stipends do not reduce the hours. Class size reductions are politically difficult and rarely sustained. And professional development that adds more time commitments to an already overloaded schedule can actually make things worse.

The more promising direction is operational: using AI-assisted grading tools to handle the most repetitive and time-consuming components of the essay grading process while keeping the teacher in a supervisory role. Recent data suggests that teachers who use AI tools weekly save an average of nearly six hours per week. For a writing teacher grading 120 essays every two weeks, that is the difference between grading consuming every evening and grading being finished by Wednesday.

Protecting Writing Instruction by Reducing Its Cost

The stakes of the workload problem extend well beyond teacher wellbeing, as important as that is. When grading takes too long, teachers assign fewer essays. When teachers assign fewer essays, students write less. When students write less, they develop weaker writing skills. The workload crisis is quietly degrading writing instruction at the exact moment when employers and higher education institutions are demanding stronger communication skills from graduates.

Addressing this does not require replacing teacher judgment with automation. It requires rethinking which parts of the grading process genuinely need a teacher's expertise and which parts can be responsibly handled by a tool. Rubric alignment, initial scoring, and surface-level feedback are strong candidates for AI assistance. Identifying a student's growth trajectory, connecting feedback to prior assignments, and making instructional decisions based on class-wide patterns are tasks that remain firmly in the teacher's domain. The schools that figure out this division of labor will retain their writing teachers and produce stronger student writers. The ones that do not will keep losing both.
