Mastering Your IB History IA: The Ultimate Guide

The History Internal Assessment can feel like the biggest challenge of your IB journey. It's an independent historical investigation, worth 20% of your final grade at HL and 25% at SL. But let’s reframe that: this is your chance to be a real historian. You get to choose a topic you're passionate about, dive deep into the evidence, and craft your own argument. This guide will walk you through every step, from picking a killer topic to polishing your final draft.

Deconstructing the IA: The Three Core Sections

Your 2,200-word investigation is broken down into three distinct parts. Think of them as building blocks for your historical argument.

How Your IA is Marked: The Assessment Criteria

Understanding the mark scheme is like having the rules of the game. Your IA is graded out of 25 marks, split into three criteria:

• Criterion A: Identification and Evaluation of Sources (6 marks): Assesses the clarity of your research question and the depth of your analysis of the two key sources.
• Criterion B: Investigation (15 marks): This is the big one. It evaluates the quality of your research, the strength of your argument, your critical use of evidence, and your consideration of different perspectives.
• Criterion C: Reflection (4 marks): Assesses how thoughtfully you reflect on the methods you used and the challenges historians face.

The Most Important Step: Nailing Your Research Question

A great IA starts with a great question. A question that is too broad will lead to a descriptive, shallow essay. A question that is focused, specific, and debatable is the foundation for a high-scoring IA.

Follow this three-step process to narrow down your topic:

1. Start Broad: Pick a topic or period that genuinely interests you. The Russian Revolution? The Civil Rights Movement? The Meiji Restoration? Your passion will fuel you through the research process.
2. Add Scope Limitations: Now, get specific.
   • Time Frame: Limit your focus to a few years, or even a few months. Instead of "The Russian Revolution," think "The period between February and October 1917."
   • Geography: Focus on a specific country, region, or city. Instead of "The Civil Rights Movement," focus on "The desegregation campaigns in Birmingham, Alabama."
   • Theme: Pinpoint a specific aspect, group, or policy. Instead of "The Meiji Restoration," focus on "The impact of educational reforms on the samurai class."
3. Make it Analytical: Your question must invite debate, not a simple description of events. Frame it as an evaluation.

Example: From Broad Idea to Focused Question

• Broad Topic: World War II
• Narrowed Topic: Naval warfare in the Pacific during WWII.
• Specific Focus: American code-breaking at the Battle of Midway.
• Final Analytical Question: "To what extent did American code-breaking efforts influence the outcome of the Battle of Midway in 1942?"

Finding & Evaluating Sources: The OPVL Method

Primary sources are the raw materials of history—letters, diaries, government reports, photographs, speeches, and newspaper articles from the time. You need them to build your argument. You'll find them in online archives (like the Library of Congress), university digital collections, and databases like JSTOR.

To evaluate your sources like a top historian, use the OPVL method for your two chosen sources in Part 1:

Common IA Pitfalls & How to Avoid Them

• The Mistake: Writing a narrative. Many students just describe what happened.
• The Fix: Constantly analyze. For every piece of evidence you present, ask yourself, "So what? How does this prove my point and answer the research question?"


• The Mistake: Weak source evaluation. Simply stating a source is "biased" isn't enough.
• The Fix: Be specific. Explain how and why the source's origin and purpose create specific values and limitations for answering your question.


• The Mistake: Relying only on a few secondary sources.
• The Fix: Dig deep for a variety of primary and secondary sources. Show the examiner you've done comprehensive research and considered different historians' interpretations.
