10 Proven Tips to Write a Strong IB History IA Analysis

Aim to use approximately 8–10 credible sources overall. Prioritize academically reliable material with clear authorship and purpose. Avoid sources that lack authority or historical context.

Evaluating Key Sources Critically

At least two sources must be evaluated in depth. For these key sources, address:

• Origin: who created the source and when
• Purpose: why it was produced
• Content: what the source reveals
• Context: how historical circumstances shape its perspective

You must then assess both value and limitations, considering factors such as bias, intended audience, and reliability. Evaluation should be integrated into your argument, not presented as a checklist.

Structuring the Analysis Effectively

Your analysis should follow a clear and logical structure. Two common approaches are effective:

A thematic structure, where each paragraph explores a specific argument or factor.
A chronological structure, where analysis follows developments over time.

Whichever structure you choose, each paragraph should focus on a single idea and contribute directly to answering the research question.

Engaging With Multiple Perspectives

Strong historical analysis acknowledges that the past can be interpreted in different ways.

You should:

• Compare differing interpretations from historians or sources
• Explain why these interpretations differ
• Assess which perspective is more convincing based on evidence

Where relevant, situate your investigation within broader historiographical debates.

Supporting Claims With Precise Evidence

All arguments must be supported with specific evidence. Use precise references, dates, statistics, or brief quotations where appropriate.

Evidence should always be followed by explanation. Simply presenting facts is not enough; you must explain how the evidence supports your argument and relates to the research question.

Maintaining Focus on the Research Question

One of the most common weaknesses in History IAs is drifting into narrative.

To stay focused:

• Regularly link analysis back to the research question
• Remove descriptive material that does not advance your argument
• Ensure every paragraph contributes to evaluation, not storytelling

If a sentence does not help answer the question, it should be revised or removed.

Writing Clearly and Concisely

The recommended length for the analysis section is about 500 words. This requires precision.

Use formal academic language and ensure clarity of expression. Ideas should flow logically, with clear connections between paragraphs.

Concise writing demonstrates control and confidence in your analysis.

Concluding the Analysis Effectively

End the analysis by identifying the most convincing interpretation or explanation, based on the evidence you have evaluated.

Your conclusion should:

• Be clearly supported by the analysis
• Reflect judgment rather than summary
• Reinforce how the evidence answers the research question

Avoid introducing new evidence in this section.

Referencing and Academic Integrity

Accurate referencing is essential. All sources must be cited consistently using a recognized academic style, such as Chicago or MLA.

Proper citation is required to meet the academic integrity standards set by the International Baccalaureate and to avoid plagiarism.
