About

GradeLens makes marking criteria less mysterious.

It is a second opinion for IB MYP students at Mahindra International School: a predicted level for each criterion, read against the rubric and lowered for a specific teacher when their real marks show they mark harder, never raised. The teacher's mark stays the official one.

How it works

From rubric to prediction.

Read the full method, uncertainty, and limitations.

01

The rubric says what

Every MYP criterion comes with band descriptors. GradeLens reads them the same way an assessor would: what the task asked for, and what the work contains.

02

The marking says how much

Two teachers can read the same descriptor differently. GradeLens compares its predictions with the real marks each teacher gave. When a teacher marks harder, their levels are lowered; a real mark never raises one, and with no real marks to compare with, nothing is adjusted.

03

You get a prediction and three fixes

A level for each criterion, a confidence that reflects how much evidence exists, and the three changes most likely to move the mark. The writing stays yours.

Questions

Frequently asked.

What is GradeLens?
GradeLens is a web tool for IB MYP students at Mahindra International School. You upload a draft together with the task sheet and rubric, choose the teacher who will mark it, and get a predicted level (0–8) for each assessed criterion, plus the changes most likely to raise it.
Is the prediction my real grade?
No. It is an estimate: GradeLens reads your work against the rubric, then lowers a level for a teacher whose real marks show they mark harder. Real marks never raise a level, and with none to compare with, nothing is adjusted. Your teacher's mark is always the official one. GradeLens never writes grades back into any school system.
Where does the evidence come from?
From real marks that students add: the mark their teacher gave for work GradeLens predicted, or past marked work they chose to contribute (the mark, the criterion levels and the teacher's written feedback). Patterns only appear once there are at least six supporting pieces from three or more students.
Does GradeLens rate or rank teachers?
Never. The patterns describe the work (for example, "higher marks tend to require explicit evidence"), not the teacher's personality or strictness, and no teacher is compared with another.
Who can see my draft?
Only you. Drafts and predictions live in your own account and are not shown to other students, to teachers, or on any public page. Two things on a teacher's public page are worked out from the marked work of students who left the box ticked, and both are aggregates that never name a student or show a piece of work: the teacher's patterns, shown once at least six pieces from three different students support one, and the GradeLens track record (how many of the newest 10 predictions were at or below the real marks students added, counting predictions made from 15 October 2026 on), shown once there are at least 5 real marks from 3 different students. To produce a prediction, the draft is sent to the GradeLens grading model and to a feedback model for processing. Unless you untick the box on the review step, an anonymised copy (names and identifiers removed) is also kept to train the grading model and to help read teacher patterns; the privacy page explains how.
Does GradeLens detect AI writing?
No, and it never will. It does not try to decide who or what wrote a piece of work; it only estimates how the work would be marked.
Who built it?
A student at Mahindra International School, as a school project, with the aim of making marking criteria less mysterious.
