How Our TOK Essay Grader Works

  • Step 2

  • Step 3

    Read Your Assessment Report

    See an estimated mark out of 10 with its level, a level for each of three strands with quotes from your essay, and three priorities for your next draft.

Why Use Our TOK Essay Grader Instead of a General AI Chat

TOK Essay Grader: How the TOK Essay Rubric Turns Into a Mark Out of 10

A TOK essay grader reads a Theory of Knowledge essay against the TOK essay rubric and estimates the mark an IB examiner could give it on the 0–10 scale. The Writers Per Hour TOK Essay Grader checks the focus on your prescribed title, the arguments and examples, and the perspectives and implications, then returns a mark range, a level, quotes from your own essay and three priorities for revision. It is an estimate for planning your next draft, not an IB mark.

What Is the TOK Essay Marked Out Of?

The TOK essay is marked out of 10. An IB examiner reads the whole essay and gives it one mark, without adding up separate scores for separate criteria. The essay answers one of the six prescribed titles the IB releases for each session, and it may be no longer than 1,600 words.

The TOK essay in four figures

  • 6 titles
  • 1,600 words
  • 0–10 marks
  • 2/3 of the TOK grade

You choose one of the six prescribed titles for your session and write up to 1,600 words. Examiners stop reading at the limit. The essay is marked out of 10 and makes up two thirds of the Theory of Knowledge grade; the exhibition makes up the other third.

Footnotes and the bibliography do not count towards the 1,600 words, but quotations in the body of the essay do. If you are not sure where your draft stands, paste it into our word counter before you grade it: the TOK essay grader shows the word count in its report and warns you when the text runs over the limit.

How the TOK Essay Rubric Works

The TOK essay rubric is holistic. Examiners ask one main question of the essay: does it explore the prescribed title in a clear, coherent and critical way? They then pick the level whose description fits the essay best and settle on a mark within that level.

A holistic rubric rewards the essay as a whole. A brilliant example does not lift an essay that drifts away from its title, and one weak paragraph does not sink an essay that holds its argument together. This is why the TOK essay criteria are hard to tick off as a checklist: what the examiner weighs is how well the parts work together to answer the title.

An essay that does not answer one of the six titles for its session gets 0, however well it is written. The grader checks this first, and the report says so plainly when an essay seems to answer a different question.

The Five Levels of the TOK Essay Mark Scheme

The TOK essay mark scheme has five levels above zero, each worth two marks. The Writers Per Hour grader names the level it sees first and then gives the mark as a range of one mark either side, because two examiners can read the same essay a mark apart.

Levels and marks

  • Excellent

    9–10 marks

    The essay stays on the title from start to finish and weighs its own claims with insight.

  • Good

    7–8 marks

    A focused, well-supported answer whose evaluation is sound but not always taken further.

  • Satisfactory

    5–6 marks

    The title is answered, but the arguments are uneven and the examples do part of the work.

  • Basic

    3–4 marks

    The essay touches the title but describes more than it argues.

  • Rudimentary

    1–2 marks

    There is little connection to the title and very little argument.

What the TOK Essay Grader Checks in Your Essay

The TOK essay grader breaks the holistic judgement into three strands, so you can see which part of the essay holds the mark up and which part pulls it down. The strands are our way of laying out the report, not separate IB criteria: the mark itself is still one best-fit judgement of the whole essay.

From Strand to Report
StrandWhat an examiner looks forWhat the report shows
Focus on the title and areas of knowledgeEvery part of the essay answers the prescribed title, and the areas of knowledge serve that answerThe level for this strand, the areas of knowledge the essay develops, and where the focus slips
Arguments and examplesClaims are developed, supported and linked, with specific examples that do real workQuotes from your essay that show the strongest and weakest arguments
Perspectives and implicationsDifferent points of view are weighed, and the essay says what follows from its conclusionsWhat to change so the evaluation goes further than a list of views

Each strand gets its own level, the evidence quoted from your text, and one change to make. The report ends with three priorities for revision in the order that should matter most for the mark.

From the Essay Mark to the TOK Grade

The essay mark is only part of the TOK grade. The essay out of 10 counts for two thirds of the result and the exhibition for one third, and the IB turns the combined score into a letter grade from A to E. The TOK grade boundaries are set by the IB for each session, so the same essay mark does not always lead to the same letter.

The letter grade then matters beyond the course. The TOK grade and the extended essay grade together give up to three core points towards the IB Diploma. A one-mark gain on the essay can be the step from one grade boundary to the next, which is why the grader lists what to revise rather than only the estimate.

What a TOK Grader Can and Cannot Tell You

An Estimate, Not an IB Mark

The TOK Essay Grader by Writers Per Hour is an AI model that estimates a mark from the text you give it. It is not linked to the International Baccalaureate, it has not seen how your teacher or examiner will read the essay, and its range can differ from the final mark. It reads only the essay text, not your planning documents or teacher comments. It does not write or rewrite any part of your essay.

Use the estimate to compare drafts. Grade the first full draft, work through the three priorities, and grade the new version: if the same strand moves up a level, the revision did what you meant it to do.

TOK Essay Examples and Expert Help

A mark makes more sense next to real essays on real titles. Our TOK essay examples show how students have answered different prescribed titles, from the choice of areas of knowledge to the examples that carry the argument.

If the report shows that the essay needs more than a revision, the Writers Per Hour TOK essay writing service puts you in touch with a writer who works with Theory of Knowledge and its prescribed titles.
