How to Grade Essays with FirstMarker (And Why Your Rubric Matters)

Grading essays can be time-consuming and inconsistent — especially when relying on traditional rubrics designed for human interpretation.

With FirstMarker, you can automate essay grading quickly and consistently. However, to get the best results, you need to understand one key concept:

Not all rubrics are AI-friendly.

Why Traditional Rubrics Don’t Work Well with AI

Most classroom rubrics are:

• Visually designed (tables, boxes, diagrams)
• Ambiguous in wording
• Dependent on teacher interpretation

While this works for humans, it creates problems for AI systems like FirstMarker.

Common Issues:

• ❌ Vague descriptors like “good use of language”
• ❌ Missing scoring rules (how much is each section worth?)
• ❌ Visual layouts that don’t translate well to text
• ❌ Criteria that overlap or are not clearly separated

AI needs structured, explicit, and unambiguous instructions.

What Makes a Rubric “FirstMarker-Friendly”?

To get consistent grading results, your rubric should be:

1. Text-Based (Not Visual)

Avoid diagrams and graphic organizers. Use clear text instead.

2. Explicit Scoring Rules

Each criterion should define:

• What is being assessed
• What full marks look like
• What partial marks look like

3. Separated Criteria

Each skill must be independently graded:

• Ideas
• Vocabulary
• Mechanics
• Spelling

4. Defined Language

Avoid vague words like:

• “good”
• “some effort”
• “well written”

Replace them with measurable descriptions:

• “uses at least 3 descriptive (WOW) words”
• “includes all required sections”

Example: Weak vs Strong Rubric

❌ Weak (Human-Friendly Only)

Uses good vocabulary and interesting ideas.

✅ Strong (AI-Friendly)

Vocabulary:

• 3 marks: Uses 5 or more descriptive (WOW) words
• 2 marks: Uses 3–4 descriptive words
• 1 mark: Uses 1–2 descriptive words
• 0 marks: No descriptive words used

Step-by-Step: Grading Essays in FirstMarker

💡 Tip: Saved test names auto-fill these fields next time, making grading faster.

Step 2: Upload the Rubric

Upload your rubric as an image.

⚠️ Important: Even though you upload an image, your rubric should still be:

• Clear
• Structured
• Text-based in design

Step 3: Upload Student Work

• Upload scanned pages or images
• Ensure:
  • Good lighting
  • Clear handwriting
  • Flat alignment

Step 4: Grade the Work

• Click grade
• FirstMarker analyzes the script
• Marks are generated based on your rubric

You can also:

• Run grading multiple times to check consistency
• Compare outputs

Pro Tips for Better Results

✅ Use Checklists Instead of Paragraphs

AI performs better with structured lists than long descriptions.

✅ Define “WOW Words”

Instead of saying “good vocabulary,” specify:

“Uses descriptive words such as: enormous, whispered, dazzling”

✅ Avoid Overlapping Criteria

Bad:

• “Creativity” and “Ideas” (too similar)

Better:

• “Includes all required ideas”
• “Uses descriptive language”

✅ Keep It Simple

More complexity ≠ better grading

Final Thought

FirstMarker is powerful — but it depends on how well you communicate your rubric.

The clearer your rubric, the more consistent your grading.

If you design your rubric for AI instead of humans, you’ll get:

• Faster grading
• More reliable scores
• Less frustration
