Problem: “Protected from Hallucination/AI” or No Feedback Returned
Why it happens:
The system couldn’t confidently extract a clear prompt or task from the file.
The student's response includes unclear or irrelevant formatting.
The assignment is too long.
Fix it:
Double-check that each file only includes one answer.
If the prompt is embedded in the student’s file, remove it. Your assignment instructions should carry that instead.
There is no hard limit, but anything over 15 pages may cause issues. Shorter submissions usually run smoother.
Problem: Essay not graded as expected (e.g. off-topic score, irrelevant feedback)
Why it happens:
The assignment instructions were too vague or included steps unrelated to the task.
The rubric may not match the kind of writing being evaluated.
Fix it:
Review the assignment instructions, simplify, and focus only on what the student is expected to write.
Remove directions about turning in, formatting, or using other tools.
Ensure the rubric criteria match what you’re asking students to do
Problem: The Assignment won’t upload or import.
Why it happens:
The file might be too large or formatted incorrectly.
Some LMS imports fail if multiple prompts or attachments are included.
Fix it:
There is no hard limit, but anything over 15 pages may cause issues. Shorter submissions usually run smoother.
If importing from Google Classroom, make sure each file is a standalone document with only the student’s response.
Problem: Grading multiple questions at once doesn’t work
Why it happens:
CoGrader is optimized for one task at a time. Multi-question assignments can confuse the AI and break scoring.
Fix it:
If you need to grade multiple short responses, split them into separate assignments.
