What is Orbit AI?

The problem

Indian teachers handle 40-60 students per section across multiple classes, and grading open-ended work — essays, projects, long answers, holiday assignments — eats evenings and weekends. Marking is also inconsistent: the same answer can score differently depending on the teacher's mood, the time of day, or which paper in the pile it is. Building a fair rubric from scratch for every CBSE/ICSE/State board assignment is tedious, so most teachers fall back to a single number out of 10 with no feedback the child can act on. Parents then ask "why only 6 marks?" and there is no clear answer to point to.

A real sample for an Indian classroom

ICSE · Class 9 · English Language — Analytical essay: 'Is social media good for teenagers?' (20 marks)

Generated by Orbit

Analytical Essay Rubric — ICSE Class 9 English

Topic: “Is social media good for teenagers?”  |  Total: 20 marks  |  4 criteria × 4 performance levels

Criterion Exemplary (full marks) Proficient Developing Beginning
Thesis & argument
5 marks
Clear, debatable thesis stated early; a consistent point of view runs through the whole essay. (5) A clear stand is taken; argument mostly stays on track with minor drift. (4) A position is implied but not clearly stated; argument wanders. (2–3) No clear stand; the essay lists points without an argument. (0–1)
Evidence & reasoning
5 marks
Each point backed by relevant examples or reasons; counter-view acknowledged and answered. (5) Most points supported with examples; reasoning is sound. (4) Some points unsupported; examples are vague or repeated. (2–3) Opinions stated with little or no support. (0–1)
Structure & coherence
5 marks
Clear introduction, body and conclusion; paragraphs linked with smooth connectives. (5) Logical paragraph order; a few weak links between ideas. (4) Some paragraphing, but order feels random in places. (2–3) One block of text with little structure. (0–1)
Language & mechanics
5 marks
Varied vocabulary and sentence types; grammar, spelling and punctuation almost error-free. (5) Mostly accurate; a few slips that don’t hinder meaning. (4) Repeated errors in grammar/spelling; meaning sometimes unclear. (2–3) Frequent errors make the essay hard to follow. (0–1)

Worked example — how one paragraph maps to the rubric

“Social media is bad for teenagers. My friends use Instagram all day and they get distracted from studies. So I think it is not good and students should not use it during exams.”
Criterion Level Marks Feedback for the student
Thesis & argument Proficient 4 A clear stand is taken in the first line — good. State it as a fuller thesis next time.
Evidence & reasoning Developing 2 One personal example only; add a second reason and consider the other side of the argument.
Structure & coherence Developing 2 Ideas are linked but cramped into one short paragraph; split into intro, body and conclusion.
Language & mechanics Proficient 3 Sentences are correct but simple; try a few connectives like ‘however’ and ‘therefore’.
Total 11 / 20 Solid stand, but back it with stronger evidence and proper paragraphing to move up a band.

Sample generated by Inforida Orbit. You can rename criteria, change mark bands and edit every comment before sharing. Final marks always stay in the teacher’s control.

A 4-criteria analytical essay rubric with 4 performance levels each, plus a worked example showing how one student paragraph maps to the rubric. Edit any descriptor or mark band before you use it.

How it works

  1. Tell Orbit the assignmentPick your board, class, subject and topic, then describe the assignment — an ICSE Class 9 analytical essay, a CBSE Class 7 history project, a State board Class 10 long answer. Set how many criteria, how many performance levels and the total marks.
  2. Get a board-aligned rubricOrbit drafts a complete rubric — named criteria, descriptors for every performance level and a mark band for each — calibrated to the language and rigour expected at that class and board. Edit any wording or weighting inline.
  3. Grade student work against itPaste a student's answer and Orbit maps each criterion to a level, suggests a score and writes a short, specific comment ('thesis is clear but two body paragraphs lack evidence'). You stay in control — accept, adjust or override every mark.
  4. Share consistent feedbackExport the rubric and the filled-in grade sheet, or reuse the rubric across the whole section so every child is marked on the same yardstick. Inside a school's Inforida subscription, grades and remarks flow into the Nucleus gradebook and parent app.

What it means for you

Hours back every weekStop building rubrics from scratch and writing the same feedback 50 times. A section's worth of essays gets a fair first-pass score and specific comments in minutes, not a whole weekend.
Consistent, defensible markingEvery child in the section is judged against the same criteria and mark bands, so the 14th paper is marked as carefully as the 1st. When a parent asks 'why this mark?', you have a clear rubric to point to.
Feedback students can act onInstead of a bare '6/10', each child sees which criterion cost them marks and exactly what to fix next time — turning grading into actual teaching.
Board-appropriate rigourRubrics use the language and expectations suited to your board and class, from a State board Class 6 paragraph to an ICSE Class 9 analytical essay or a CBSE Class 12 source-based answer.
Reusable across the schoolSave a rubric once and reuse it across sections, terms and colleagues. In a school's Inforida subscription, marks and remarks sync to the Nucleus gradebook and reach parents in the app.
