A typical teacher spends about 5 hours a week grading and giving feedback, on top of a 54-hour work week. For English teachers in essay season, it is a lot more. Here is where that time goes and what actually brings it down.
Key takeaways
- About 5 hours a week of grading and feedback is typical (Merrimack College Teacher Survey, 2022).
- Teachers work a median of 54 hours a week, and only 46% of their time at school is spent teaching.
- Essays are the big time sink: one set of 150 can take 25 hours.
- Rubrics, fewer detailed-feedback assignments, peer review, batching and an AI first pass all cut the load.
The numbers: teacher grading time statistics
In the 2022 Merrimack College Teacher Survey, run by the EdWeek Research Center, a typical teacher spent about 5 hours a week grading and giving feedback. Teachers of writing-heavy subjects often spend far more. And while teachers work a median of 54 hours a week, only 46% of their time in the school building goes to teaching. The rest goes to grading, planning and administrative work. RAND’s 2024 survey tells the same story from another angle: 53 hours a week on average, with about 15 of them outside contract time.
Grading time by assignment type
Rough estimates for two classes (60 students), grading thoroughly with written feedback:
| Assignment type | Time for 60 students |
|---|---|
| Multiple choice quiz | About 50 minutes |
| Short answer quiz | About 2 hours |
| 5-paragraph essays | 12+ hours |
| Research papers | 15 to 20 hours |
Our estimates, based on typical per-paper times. Your numbers will depend on length, grade level and how much you write back.
Why does grading take so much time?
Volume
6 classes of 25 students means 150 essays. At 10 minutes each, that’s 25 hours for one assignment.
Good feedback takes careful reading
Feedback is one of the strongest influences on learning in Hattie and Timperley’s research, but useful feedback means reading closely and writing specific comments.
The feedback tradeoff
Grade fast and the feedback gets thin. Grade carefully and the hours pile up.
Admin on top
Entering grades, calculating scores, report cards and parent emails all add up.
What too much grading really costs
Teacher burnout
A 53- or 54-hour week, with grading spilling into nights and weekends, isn’t sustainable for long. Grading fatigue lowers feedback quality, and the constant pressure feeds turnover. When strong teachers leave because the workload is unworkable, students lose. (More on that in teacher burnout is real.)
Slow feedback helps less
Feedback is most useful while the work is still fresh in students’ minds. When an essay comes back two weeks later, many students barely remember writing it, and the chance to learn from the comments shrinks.
Opportunity cost
Every hour spent grading is an hour not spent on:
- Planning more engaging lessons
- One-on-one time with students
- Professional learning
- Your own family and life
Teachers deserve their evenings and weekends. Weekend grading shouldn’t be a normal part of the job.
5 ways to grade faster that actually work
You don’t have to accept grading overload. Here is what research and experienced teachers point to:
Grade smarter, not everything
Not every assignment needs detailed feedback. Pick the pieces that matter most and give quick checks on the rest.
Use the same rubric consistently
A familiar rubric speeds up your decisions and makes your feedback clearer to students.
Use peer review for first drafts
Students catch the obvious issues, so your read can focus on the bigger ones.
Batch similar tasks
Grade one question across all papers before moving to the next. You stay in one frame of mind.
Use AI for a first pass you review
Let AI score and draft feedback, then check the outliers and adjust. See what the research says about AI grading accuracy before you start.

AI grading vs. manual grading: time comparison
| Assignment type | Manual (30 students) | With AI (30 students) | Time saved |
|---|---|---|---|
| 5-paragraph essay | 5 to 6 hours | 30 to 45 min (review only) | About 80% |
| Short answer (5 questions) | 2 to 3 hours | 15 to 20 min | About 85% |
| Research paper (8 to 10 pages) | 8 to 12 hours | 1 to 1.5 hours | About 87% |
| Multiple choice quiz | 50 to 60 min | Auto-graded | Nearly all |
| Lab report | 4 to 5 hours | 45 to 60 min | About 80% |
| Creative writing piece | 3 to 4 hours | 30 to 45 min | About 75% |
The AI column includes your time to review and adjust every score before returning work. The manual column assumes thorough rubric-based grading with written feedback. Try it on one assignment and time yourself.
Frequently asked questions
How many hours a week do teachers spend grading?
In the 2022 Merrimack College Teacher Survey, run by the EdWeek Research Center, a typical teacher spent about 5 hours a week grading and giving feedback on student work. Teachers of English and other writing-heavy subjects often spend far more, especially in weeks when essays are due.
How long does it take to grade one essay?
Our estimate: about 5 to 20 minutes for a 5-paragraph essay with real written feedback, depending on length, grade level and how much you comment. With 60 essays, that is roughly 5 to 20 hours for one assignment.
Do teachers grade on weekends?
Many do. The Merrimack survey found a median work week of 54 hours, and RAND’s 2024 State of the American Teacher survey found that about 15 of teachers’ 53 weekly hours fall outside contract time. Grading is one of the main things that spills into evenings and weekends.
How can teachers reduce grading time?
Use the same rubric consistently, give detailed feedback on fewer assignments, use peer review for first drafts, batch similar grading together, and let an AI tool take a first pass that you then review and adjust.
Is AI grading accurate enough to use?
For a first pass, often yes. Flodén (2025) found 70% of ChatGPT’s exam grades within 10% of the teacher’s grade, but other studies show AI is too lenient on weak work and too harsh on strong work. Use AI for first-pass scores and feedback drafts, then review every grade yourself.
What grade level spends the most time grading?
High school English and writing teachers usually spend the most. Many teach 5 or 6 sections of 25 to 35 students (125 to 210 students in all), and essays, research papers and literary analysis take the longest to evaluate.
What share of a teacher’s time is spent teaching?
In the 2022 Merrimack College Teacher Survey, teachers worked a median of 54 hours a week and spent only 46% of their time in the school building teaching. Grading, planning and administrative work take much of the rest.
Does grading overload cause teachers to leave the profession?
It is part of the picture. Grading is a big piece of the workload behind burnout. RAND’s 2024 survey found teachers worked 53 hours a week on average, about 15 of them outside contract time. Cutting grading time is one of the most direct ways to make the job sustainable.
