Philosophy IA Criteria Guide

Identify the philosophical issue quickly, then build a clear and evaluated response from start to finish.

Use this guide to keep the stimulus connection explicit, the structure easy to follow, and the argument focused on justified philosophical analysis.

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: Identification of issue and justification (3 marks)

How clearly you name the philosophical issue in the stimulus and justify why the stimulus raises it.

Stronger evidence

The issue is identified explicitly, with a clear justification of the link to the stimulus.

Early-stage evidence

The issue is implied rather than stated, and the link to the stimulus is not justified.

Criterion B: Clarity (4 marks)

How well structured, focused, and clear the response is.

Stronger evidence

Well structured, focused, clear, and coherent.

Early-stage evidence

Poorly structured, or structured but barely focused on the task.

Criterion C: Knowledge and understanding (4 marks)

How accurate and relevant your philosophical knowledge is, how well you explain the issue, and how you use philosophical vocabulary.

Stronger evidence

Relevant, accurate, detailed knowledge, a well-developed explanation, and appropriate vocabulary throughout.

Early-stage evidence

Little relevant knowledge, a minimal explanation of the issue, and missing or misused philosophical vocabulary.

Criterion D: Analysis (8 marks)

How developed your critical analysis is, how well examples support it, and how you handle counter-arguments.

Stronger evidence

Well-developed critical analysis, well-chosen examples, and counter-arguments analysed convincingly.

Early-stage evidence

Mostly descriptive, with little analysis and few or no examples.

Criterion E: Evaluation (6 marks)

How well you evaluate other interpretations, justify your points, and reach a consistent conclusion.

Stronger evidence

Clear evaluation of other views, nearly all points justified, a consistent position, and a clear conclusion that matches the argument.

Early-stage evidence

Little evaluation of other views, some main points justified, and no relevant conclusion.

Criterion B: Clarity (4 marks)

MarksWhat the draft currently shows
0Nothing in the work reaches the lowest band.
1Poorly structured, or structured but barely focused on the task.
2Some structure, though the point is not always clear.

4Well structured, focused, clear, and coherent.

Criterion C: Knowledge and understanding (4 marks)

MarksWhat the draft currently shows
0Nothing in the work reaches the lowest band.
1Little relevant knowledge, a minimal explanation of the issue, and missing or misused philosophical vocabulary.
2Some knowledge with gaps in accuracy or relevance, a basic explanation, and vocabulary used only sometimes appropriately.
3Mostly accurate, relevant knowledge and a satisfactory explanation; vocabulary is used, though not always appropriately.
4Relevant, accurate, detailed knowledge, a well-developed explanation, and appropriate vocabulary throughout.

Criterion D: Analysis (8 marks)

MarksWhat the draft currently shows
0Nothing in the work reaches the lowest band.
1-2Mostly descriptive, with little analysis and few or no examples.
3-4Limited analysis, more description than analysis, with some suitable examples.
5-6Analysis that lacks development, suitable examples, and counter-arguments identified.
7-8Well-developed critical analysis, well-chosen examples, and counter-arguments analysed convincingly.

Criterion E: Evaluation (6 marks)

MarksWhat the draft currently shows
0Nothing in the work reaches the lowest band.
1-2Little evaluation of other views, some main points justified, and no relevant conclusion.
3-4Some evaluation of other views, many points justified, and a conclusion that may not fully match the argument.
5-6Clear evaluation of other views, nearly all points justified, a consistent position, and a clear conclusion that matches the argument.

Build Sequence

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

Step 1

Name the issue early

Translate the stimulus into one precise philosophical issue and justify why that issue is the right focus.

Step 2

Build a clean structure

Organize the response so the claim, reasoning, and transitions are easy to follow at every step.

Step 3

Use philosophical vocabulary accurately

Define the key terms you rely on and keep the language precise rather than decorative.

Step 4

Balance analysis and evaluation

Develop counter-arguments and alternative views instead of stopping at description.

Submission Checklist

  • The philosophical issue is explicitly identified and justified.
  • The response is structured and easy to follow.
  • Philosophical terms are accurate and relevant throughout.
  • Evaluation is clearly tied to the argument, not added at the end as an afterthought.

Quick Wins

  • Write the issue statement before drafting the body so the response stays focused.
  • Turn one descriptive paragraph into a claim-plus-counterclaim structure.
  • Use one sentence at the end of each paragraph to signal why it matters philosophically.
