Rubric Feedback Drafting
Teachers spend evenings typing repetitive comments into student work, so feedback shrinks to a few hurried lines. Drafts cite specific evidence from each student's own text, so the feedback is grounded and personal rather than generic.
01The offer
For Heads of English or History in secondary schools, turn student submissions and a marking rubric into draft feedback comments with cited evidence and a next action. Address the recurring problem: teachers spend evenings typing repetitive comments, so detailed feedback shrinks to a few hurried lines. The value hypothesis is a faster, more consistent feedback process with teacher oversight; the pilot must establish whether teachers trust and adopt the drafts.
- For
- Heads of English or History in secondary schools
- Takes in
- Student submissions and a marking rubric
- Delivers
- Approved feedback comments with cited evidence and next actions
- Message
- Draft personalised feedback for every student against your rubric, so you edit and release instead of starting from a blank page.
- Lead magnet
- A free sample report showing draft feedback for one uploaded student submission.
02How it works
- Extract text from student submissions
- Map each submission against rubric criteria
- Draft a three-sentence comment per criterion with evidence
- Flag contradictions or missing evidence
- Present drafts in a review queue for editing
- Export approved feedback to a spreadsheet or LMS-ready format
Workflow
Upload student files, set rubric criteria, run the drafting process, review drafts in the queue, edit comments, approve the batch, and export feedback. Start with student submissions and a marking rubric and finish with approved feedback comments ready for the LMS.
AI and people
Use language models to read each submission, extract evidence, and draft comments against rubric criteria. Flag logical inconsistencies or missing evidence automatically. A teacher reviews every draft and approves or edits before anything is released; no comment reaches a student without human sign-off.
Screens
Key screens: Upload queue, rubric setup, draft review. Use a batch upload screen for student files, a rubric mapping screen for criteria, and a review queue showing one student's draft comments per criterion with evidence highlights. Allow inline editing and a toggle to view the original submission. Provide an approve-all button with a confirmation step. In this product, the first view is upload queue, followed by rubric setup and draft review.
Admin
Teacher accounts, batch versions, rubric versions, approval states, edit history, export logs, and a record of which comments were edited versus approved as drafted.
03Market gap
Alternatives buyers use today
Teachers type comments manually or use generic comment banks. This differs by generating tailored, evidence-based drafts that still require teacher approval.
Where this wins
The rubric mapping and evidence extraction improve with more use, creating a feedback style profile per teacher that becomes harder to replicate.
04Why now
Education teams are adopting AI for exactly this kind of repeatable work, and the cost of language and vision models has dropped far enough that a narrow, reviewed workflow pays back quickly. The buyer already feels the problem: teachers spend evenings typing repetitive comments into student work, so feedback shrinks to a few hurried lines.
05Proof & signals
Channels where buyers gather: Education conferences, teacher forums, and direct outreach to heads of department via school email lists.. Metrics that prove it works: Time saved per marking batch and percentage of drafts approved without major edits..
Paid pilot
A paid pilot with one secondary school department proves it by measuring time spent on feedback per batch and teacher approval rate. Baseline is current manual time; success is a 30% time saving with at least 80% of drafts accepted without major edits.
06Execution plan
MVP
A single-teacher pilot accepting Word documents and a plain-text rubric. First two modules: text extraction and draft generation. Manual review in a spreadsheet output.
First 30 days
Week 1: Build text extraction and rubric input. Week 2: Implement draft generation with evidence citation. Week 3: Create the review queue and export. Week 4: Run a single-teacher pilot and collect feedback.
After the pilot
Automate formatting for specific LMS fields, add batch approval workflows, and introduce a feedback history per student to track progress over terms.
Retention
The tool becomes part of the marking cycle each term; usage history and saved feedback styles make switching back to manual work costly.
Integrations
Start with CSV export for LMS import, then add Google Classroom and Moodle APIs.

Revenue model to test
Test pricing at USD 49 per teacher per term, with a departmental discount for five or more licences.
Cost drivers
Language model API usage per submission, basic hosting, and minimal support overhead.
Safeguards
Teachers must approve every comment before export. The system must not release feedback automatically, must not alter grades, and must flag any submission it cannot read clearly for manual review.
