The method
How GradeLens turns a draft into feedback.
GradeLens is a student-built web tool for IB MYP students at Mahindra International School. It reads a draft against the supplied task sheet and rubric, estimates levels for the assessed criteria on a 0–8 scale, and suggests improvements. The teacher’s mark remains official.
An independent student project. Your teacher's mark is always the official one.
From draft to report
The rubric comes first.
The prediction depends on the work and assessment context you supply. Real marking evidence can make an estimate more cautious; it cannot turn an estimate into an official result.
Start with your work and rubric
Add your draft, the task sheet, and the rubric. Choose the teacher and the criteria being assessed. The task and rubric provide the context for the prediction.
Read the work against the criteria
GradeLens checks the evidence in the submitted work against the supplied band descriptors. It estimates criterion levels and looks for specific gaps you can address.
Check against real marking evidence
When real marks show that this teacher marks harder than GradeLens predicted, the estimate can come down. Real marks never raise a prediction. Without comparable real marks, no teacher adjustment is applied.
Review the estimate and improve your draft
The report shows levels or ranges when the evidence supports them, explains uncertainty, and suggests three changes. With too little evidence, a number may be withheld. You decide how to revise your own work.
What the result means
Useful feedback, with clear limits.
A predicted criterion level describes this draft against this rubric. It can help you decide what to revise, but it can be wrong and does not replace your teacher's judgment.
| In your report | What it means | Its limit |
|---|---|---|
| Criterion level or range | An estimate on the rubric's 0–8 criterion scale. | Not an official final subject grade. |
| Teacher adjustment | A downward adjustment when comparable real marks support it. | No adjustment without real marking evidence. |
| Confidence | How much evidence supports the estimate. | A number may be withheld when evidence is too weak. |
| Suggested improvements | Three changes to consider in your own revision. | No guaranteed increase in the teacher's mark. |

Common questions
Before you use a prediction.
- Is GradeLens an official IB or school grading service?
- No. GradeLens is an independent student project, not an official service of the International Baccalaureate or the school. Its predictions are feedback on a draft. Your teacher decides the official mark.
- What does a predicted level of 0–8 mean?
- It is an estimate against an assessed criterion in the rubric you provide. It is not an official final subject grade, an examination result, or a promise of the mark your teacher will award.
- What does teacher adjustment mean?
- GradeLens compares predictions with real marks that students add for that teacher. Evidence of harder marking can lower a prediction; real marks never raise it. If there are no comparable real marks, the rubric estimate is left unadjusted.
- How accurate are the predictions?
- There is no single verified accuracy percentage for every teacher, task, or student. Predictions can be wrong. Confidence and ranges reflect the available evidence. Where enough consenting real marks exist, a teacher page can show an aggregate track record of recent predictions compared with real marks.
- What should I provide for useful feedback?
- Provide the actual draft, the complete task instructions, and the rubric for the criteria being assessed. Text, PDF, and DOCX drafts are supported. Missing context or unclear evidence can lead to wider ranges or no numerical prediction.
- Does GradeLens detect AI writing or write my assignment?
- GradeLens does not detect whether a person or AI wrote a piece of work. It gives criterion-based feedback and suggested changes rather than a finished replacement assignment. The writing and revision decisions stay yours.
- Are my submissions public?
- Your drafts and predictions are kept in your account and are not published on teacher pages. Grading and feedback models process the work you submit. Public teacher insights use aggregates subject to consent rules. The privacy policy explains processing, the improvement consent choice, and how to opt out.
