EE Playbook

Math EE Criteria Guide

Show a focused mathematical investigation with accurate reasoning and a convincing line of argument.

This guide keeps the extended essay tied to a focused mathematical question, a defensible method, and a conclusion that follows from the mathematics rather than from intuition alone.

Mathematics: Applications and Interpretation EE

Assessment criteria

See what each criterion measures, how many marks it carries, and what stronger evidence usually looks like.

Criterion names, marks, and mark bands follow the IB subject guide. The band descriptions are our own summaries, so check your subject guide for the exact wording.

Criterion A: Focus and Method (6 marks)

How clearly the Mathematics essay introduces its topic, states a focused research question, and uses a suitable method.

Stronger evidence

The topic is explained accurately, the research question is clear and focused, and the method is complete, with sources or methods chosen for good reasons.

Early-stage evidence

The topic is unclear or incomplete, the research question is vague or too broad, and the method is limited.

Criterion B: Knowledge and Understanding (6 marks)

How accurately the essay uses Mathematics knowledge, concepts, terminology, and sources.

Stronger evidence

Subject knowledge is excellent, and terminology and concepts are used accurately and consistently.

Early-stage evidence

Subject knowledge is limited, and terminology and concepts are used unclearly.

Criterion C: Critical Thinking (12 marks)

How well the essay researches, analyses, and evaluates its material to build a reasoned argument that answers the question.

Stronger evidence

Research and analysis are excellent, evaluation is critical, and the argument is coherent and well supported.

Early-stage evidence

Research, analysis, and evaluation are limited, and the argument is unclear.

Criterion D: Presentation (4 marks)

How well the essay's structure and layout (title page, contents, headings, figures, references) support the reader.

Stronger evidence

The structure clearly suits the subject and argument, and layout elements are used well enough to help the reader.

Early-stage evidence

The structure is broadly suitable, but some layout elements are missing or used incorrectly; these weaknesses do not seriously affect reading.

Criterion E: Engagement (6 marks)

How your RPPF reflections show decision-making, responses to setbacks, and personal engagement with the research.

Stronger evidence

The reflections evaluate decisions, show how you responded to setbacks, and show clear intellectual initiative and personal voice.

Early-stage evidence

The reflections mostly describe what happened and show little personal engagement.

Build Sequence

Did You Know? Most weak drafts fail from sequence chaos, not lack of ideas.

Step 1

Test the question early

Make sure the topic can be answered through mathematical reasoning that is deep enough for 4,000 words.

Step 2

Build the argument around definitions

Clarify assumptions, symbols, and methods so the argument does not become ambiguous later.

Step 3

Check every derivation

Verify intermediate steps and explain why each result is relevant to the research question.

Step 4

Conclude with mathematical judgement

State what the evidence proves, what it suggests, and what the investigation cannot legitimately claim.

Submission Checklist

  • The research question is mathematical and focused enough for an essay.
  • The argument stays coherent from introduction to conclusion.
  • Notation is precise and consistent throughout.
  • The conclusion is supported by the mathematics in the essay body.

Quick Wins

  • Replace one broad descriptive paragraph with a proof, derivation, or calculation that actually advances the argument.
  • Check whether every section answers part of the research question explicitly.
  • Remove any result that is mathematically interesting but irrelevant to the thesis.
