History IA Criteria Guide

Turn source selection and evaluation into a tighter, more defensible investigation.

Use this guide to keep your question narrow, make source value and limitations explicit, and connect your reflection to historical method rather than summary.

Assessment criteria

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 and evaluation of sources (6 marks)

How clearly you state your question, explain why your sources are relevant, and evaluate two of them.

Stronger evidence
A suitable question is clearly stated, source relevance is clearly explained, and two sources are analysed in detail, discussing value and limitations with reference to origin, purpose, and content.
Early-stage evidence
The question is stated and suitable sources are selected, but their relevance is barely explained and two sources are described rather than analysed.

Criterion B: Investigation (15 marks)

How clearly organized and critically analytical the investigation is, and how well evidence and perspectives support a reasoned conclusion.

Stronger evidence
Clear, coherent, and well organized; well-developed critical analysis focused on the question; effective use of evidence; perspectives evaluated; a reasoned conclusion consistent with the evidence.
Early-stage evidence
Unclear and poorly organized, with little focus and little or no critical analysis; mostly generalizations; evidence is mentioned but not analysed.

Criterion C: Reflection (4 marks)

How well you reflect on what the investigation showed you about historians' methods and their challenges.

Stronger evidence
A clear focus on historians' methods, clear awareness of their challenges or limits, and an explicit link to the investigation.
Early-stage evidence
Some discussion of what you learned about historians' methods, little awareness of their challenges or limits, and only an implied link to the investigation.

How to build it

Most weak drafts fail on order, not on ideas.

  1. 1

    Narrow the question

    Define a question that can be answered with specific evidence instead of a broad historical overview.

  2. 2

    Evaluate the sources

    Explain why your key sources matter by discussing origin, purpose, content, value, and limitations.

  3. 3

    Build the investigation

    Organize your argument around evidence and interpretation, not just chronology.

  4. 4

    Write the reflection

    Make the historian's methods and limitations explicit so the final section is clearly connected to the investigation.

Before you submit

  • The question is precise and researchable.
  • Two sources are explicitly evaluated for value and limitations.
  • Evidence from sources supports a sustained argument.
  • The reflection clearly discusses historical method and its limits.

Quick wins

  • Trim the question until it fits one clear line of inquiry.
  • Note origin, purpose, and content for every key source before drafting.
  • Use one paragraph to compare perspectives instead of retelling events.

Build A Cleaner History IA With Rubric Feedback

Marksy grades your investigation against IB criteria, highlights source-evaluation gaps, and shows where your argument and reflection need more precision. The result includes an estimated mark for every criterion, evidence from your draft, and the changes to make first. Your final mark may differ after teacher assessment or external moderation.
