The Ultimate IB History IA Guide: Topics, Structure, and Common Pitfalls

At first glance, the History Internal Assessment can seem like a daunting task. It’s worth a considerable percentage of your final grade - 25% at SL, 20% at HL - and requires you to think, research, and write as a historian. However, there is good news: a well-executed IA is one of the most rewarding elements of the IB, and it's completely within your control to score highly.

This guide will break down exactly what the examiners are looking for when they assess your IA, advise you on how to craft an engaging research question, and highlight the common mistakes that you can easily avoid.

Part 1: Deconstructing the History IA (25 Marks Total)

Your IA is a 2200-word historical investigation broken down into three key sections that are assessed separately. Understanding what each part demands is the first step to success.

Criterion A: Identification & Evaluation of Sources (6 Marks)

This is where you set the stage. You need to state and contextualise a sharp, focused research question, and then conduct a detailed analysis of two key sources that you'll be using to answer it. This means a full OPVL (Origin, Purpose, Value, Limitation) analysis for each. Don't just list the features; you must explain exactly how the origin and purpose of each source affect its value and limitations in relation to your specific question.

Suggested word allocation: 500

Criterion B: The Investigation (15 Marks)

This is the main body of your IA. It's where you answer your research question, exploring relevant perspectives drawn from a wide range of evidence. The key here is critical analysis, not just description. You must use your sources to build a coherent argument, evaluate different historical perspectives, and lead the reader to a well-supported conclusion. This section carries the most weight, so make sure it is well-organised, clear, and insightful. 

Suggested word allocation: 1300

Criterion C: Reflection (4 Marks)

In this final section, you step back from the research question itself and reflect on the process of inquiry more broadly. What did your investigation teach you about the methods that historians use? What were the challenges you faced in finding or interpreting sources? This isn't just a summary of your experience; it's a thoughtful consideration of the nature of history itself, showing your awareness of things like bias, perspective, and the construction of historical narratives. Think ToK.

Suggested word allocation: 400


Part 2: How to Choose a Winning IA Topic

Your topic is the foundation of your entire project. A great topic makes research exciting and analysis possible. A weak one leads to boredom, frustration, and a descriptive paper that will not perform well against the assessment criteria. Here’s your checklist for crafting a solid research question:

  • Find a genuine interest: You are going to be living with this topic for weeks if not months, so choose something that genuinely fascinates you. Your passion will fuel your research and shine through in your writing.
  • Look for historical debate: The best IAs explore questions that historians themselves disagree on, because these provide rich ground for argumentation among different perspectives. Avoid topics with an obvious, universally accepted answer. Your goal is to enter a historical conversation, not just report facts.
  • Narrow your focus: "The Cold War" is a course, not an IA topic. "To what extent was Nixon's Vietnamization policy a success between 1969 and 1971?" is a suitable IA topic. Narrow your focus to a specific event, a timeframe of less than a decade, or a particular group to come up with a research question that you can adequately explore within the scope of the assignment.
  • Check for source availability: You need accessible and credible primary and secondary sources. If you can't find solid academic sources within an hour of searching, it's a red flag. Be strategic with regards to the languages you speak as well; some investigations may require the ability to read primary sources in languages other than English. 
  • Ensure your topic is historical: The IB requires your topic to be at least 10 years old. This ensures enough time has passed for proper historical analysis and perspective to develop.
The Lanterna Tip: The One-Hour Source Test. Before committing to a topic, spend one hour on a preliminary source hunt. Can you find at least two promising primary sources? Can you find at least five academic books or journal articles on the topic? If not, you should pivot to another idea.

Part 3: 25 Battle-Tested IA Topic Ideas

Use these sample research questions as a launchpad to get you thinking about a suitable line of inquiry for you IA:

Revolutions and Political Upheavals

  • To what extent was the Haitian Revolution the most successful slave revolution in history?
  • How successful was Mao's Cultural Revolution in achieving its stated political goals?
  • To what extent was nationalism, rather than Prussian militarism, the primary driver of German unification in 1871?
  • An analysis of the successes and failures of the Russian Revolution's initial phase (1917-1918).
  • How did the Cuban Revolution's outcomes differ from Fidel Castro's initial promises?

Wars and Conflicts

  • How significant was German involvement in determining the outcome of the Spanish Civil War?
  • To what extent were foreign powers responsible for the escalation of the Rwandan Genocide?
  • Examine the strategic impact of the Battle of Stalingrad on the Eastern Front in WWII.
  • To what extent can Nixon's policy of "Vietnamization" be considered a military success?
  • A study of the bombing of Guernica: Was it a strategic military target or an act of terror?

Social and Cultural History

  • How significant was WWII in accelerating the women's rights movement in the United States?
  • An investigation into the role of British politics in the ineffective response to the Jack the Ripper incidents.
  • How did the New Deal's Farm Security Administration use photography as propaganda?
  • To what extent did the Industrial Revolution improve the daily lives of the urban working class in Manchester?
  • An analysis of the effectiveness of the US Civil Rights Movement's non-violent protest strategies in the 1960s.

Political Figures and Policies

  • How did Stalin's agricultural policies directly contribute to the Ukrainian Famine (Holodomor)?
  • To what extent did Napoleon III's domestic policies achieve his goal of modernizing France?
  • Was the primary purpose of the Berlin Wall to limit the freedom of East Germans or to project Soviet strength?
  • To what extent were Stalin's Five-Year Plans successful in industrializing the USSR by 1939?
  • An evaluation of Fidel Castro's social policies in Cuba: successes and failures.
Remember that these questions should be narrowed down further with focus on specific dates, locations, or groups to fit the 2,200-word limit. For example, the final question in this list could be refined by focusing on the impact of Castro's social policies on a particular social group in Cuba, such as women or children, and by specifying a timeframe. 

Part 4: Common IA Pitfalls and How to Avoid Them

Many students lose marks on the same simple mistakes. Here’s how to make sure you’re not one of them.

The PitfallThe Lanterna Fix
A descriptive and poorly focused research question:
Such as "What were the effects of the Vietnam War?" This is too broad and invites a simple, descriptive list of facts.
Frame it as a debate. Use analytical command terms and IB History concepts in your question. Formulating "To what extent..." or "How significant was..." questions forces you to take a position and argue it.
Superficial source analysis (OPVL):
Such as simply stating a source is "biased" because the author is from a certain country or has a political view.
Connect the OPVL analysis directly to your question. Explain how the origin and purpose make the source valuable or limited for answering your specific question. How does the bias manifest in the text to potentially distort the truth? What information might be omitted? What does the source reveal that makes it essential for answering your question?
Confusing description with analysis:
Your investigation becomes a play-by-play of events without an argument. You're telling a story of past events, not analyzing a historical inquiry.
Ensure that every paragraph argues a clear point, which is stated in the very first sentence. Start paragraphs with an assertion that supports your thesis, then use evidence from your selected sources to justify it. Ask yourself, "So what?" after presenting a piece of evidence, and clearly explain why it is relevant to your inquiry.
Ignoring the prescribed IA structure:
Mashing all three sections together, or putting your reflection in the conclusion of the investigation.
Use the official subheadings and sections to organise your work. Clearly label each section (A: Identification and Evaluation of Sources, B: Investigation, and C: Reflection) and ensure you fulfil the relevant requirements for each. This shows the examiner you understand the task and makes it easy to award marks according to the assessment criteria.
Exceeding the word count:
Going over the strict 2,200-word limit. Examiners are instructed to stop reading after the limit, which can cost you valuable marks.
Be a ruthless editor. Every single sentence must serve your argument. Don't waffle, avoid repetition, combine ideas, and ensure your language is precise. Remember, the bibliography and citations are not included in the word count.

The most common pitfall is writing a descriptive essay instead of an analytical investigation. Students often recount historical events rather than evaluating sources and constructing an argument. The IA is a test of your skills as a historian, focusing on critical analysis and source evaluation (OPVL), which is something our expert tutors can help you master.

A strong research question is narrow, focused, and allows for genuine historical debate. It should be analytical (e.g., 'To what extent...') and cover a topic that is at least 10 years old with accessible primary and secondary sources. If you're struggling to refine your topic, a free consultation with a Lanterna Student Success Expert can provide the clarity you need.

Our tutors are expert IB graduates who have excelled in their own History IAs. They act as mentors, guiding you through each stage: refining your research question, mastering source analysis (Criterion A), structuring your investigation (Criterion B), and crafting a thoughtful reflection (Criterion C). They provide personalised feedback to help you build confidence and improve your grade.

The Lanterna IB consultation is a free, 20-30 minute online call with a Student Success Expert. It's designed for students and parents to discuss specific IB challenges, like the History IA, and receive a personalised plan with clear priorities and next steps to improve grades and reduce stress.

This section is challenging because it requires a deep OPVL (Origin, Purpose, Value, Limitation) analysis directly linked to your question. A common mistake is being too superficial. The best next step is to get expert guidance. A Lanterna History tutor can work through your sources with you, showing you how to perform a sophisticated evaluation that impresses examiners.

Yes, completely. The 20-30 minute consultation is designed to provide genuine value and expert guidance for your IB journey. There is absolutely no obligation to purchase tutoring afterwards. Our goal is to leave you with a clear, actionable plan to help you succeed.

The consultation is for any IB student (DP1 or DP2) or parent who wants expert guidance. Whether you're feeling overwhelmed by the History IA, aiming for a top grade, or simply want to check if your study strategy is effective, our Student Success Experts can provide the personalised advice you need.

After your free call, you will have a much clearer understanding of your challenges and a strategic plan to tackle them. If you decide that tutoring would be beneficial, your Student Success Expert will match you with the ideal tutor. If not, you still walk away with valuable, personalised advice for your IB journey, at no cost.

Absolutely. A Lanterna tutor can provide a fresh, expert perspective. They can help you interpret your teacher's feedback and show you precisely how to implement it to strengthen your investigation, analysis, and structure. This targeted support is often the key to moving from a good grade to a great one.
