Claude for grading essays, done properly.
The tested prompt, the codes that help, and the setup education pros run. Copy, adapt, ship.
Grading 30+ essays with meaningful feedback takes 15-20 hours. Most teachers resort to generic comments because individual feedback at scale is unsustainable.
Three reasons this actually lands.
The prompt, the codes, the fit. Each one on its own is a nice-to-have. Together, they change the workflow.
One tested prompt, copy-paste ready. Rules baked in, placeholders marked, tone locked down. No prompt-engineering trial runs, no back-and-forth.
Prefix with PERSONA, TONE:, REFINE for compound effects. Each code is a documented technique, not a magic word.
Tuned for education workflows. Not a generic template, and not another "you are a helpful assistant" hack.
Without the pattern vs with it.
What the day looks like when you keep winging the prompt, and what it looks like when you stop.
Generic prompt. Claude writes something that could be about anyone, in any industry, from anywhere. Sounds like a template because it is one.
The CLSkills prompt with placeholders for your context. Claude writes it like a specialist who actually knows the work. Publishable after one edit pass.
You paste, Claude answers, you rewrite, you paste again. Ten minutes of back-and-forth per output. Three hours across a batch of five.
Prompt loaded once. You feed the specifics, Claude returns the finished output. Two minutes per, twenty across five. Same tone, same structure, every time.
Middle-of-the-road copy that reads AI-flavoured. Recipients notice. Response rates stay low. You end up rewriting most of it anyway.
Rubric-aligned grading with specific, actionable feedback that students can actually use to improve. Quotes their own words to show you read carefully. Cuts grading time by 60%.
Copy this, replace the placeholders, ship.
Help me grade this student essay. Assignment: [WHAT WAS THE PROMPT] Grade level: [GRADE] Rubric criteria: - [CRITERION 1]: [DESCRIPTION + POINT VALUE] - [CRITERION 2]: [DESCRIPTION + POINT VALUE] - [CRITERION 3]: [DESCRIPTION + POINT VALUE] Student essay: [PASTE ESSAY] Provide: 1. **Score**: Points for each rubric criterion with brief justification 2. **Strengths** (2-3): Specific things the student did well (quote their words) 3. **Areas for growth** (2-3): Specific, actionable feedback (not "needs improvement") 4. **One next step**: The single most important thing this student should focus on 5. **Margin notes**: 3-5 inline comments I can paste at specific spots in their essay Tone: Encouraging but honest. This is feedback for learning, not just evaluation. Be specific — "Your thesis on line 2 makes a clear claim" not "Good thesis."
