Introduction: How to Write and Score a 7 in IB Economics IA
At Quest For Success, see students underestimate the IB Economics IA — and pay for it later. The IB Economics Internal Assessment is a portfolio of three commentaries. Each commentary analyses a real-world news article using economic theory. Therefore, it directly tests how well you think like an economist.
The IA counts for 30% of your final grade at SL and 20% at HL. Consequently, it significantly impacts your overall IB score. According to the International Baccalaureate, Economics sits in Group 3 and emphasises real-world application above all else. This makes the Economics IA for IB both challenging and rewarding.
Structure of the IB Economics Internal Assessment
The IB Economics Internal Assessment consists of three separate commentaries. Each commentary covers a different unit: microeconomics, macroeconomics, and either international trade or development economics.
Furthermore, each commentary has a strict 800-word limit. Every commentary must also link to one of the nine key concepts — such as scarcity, equity, efficiency, or intervention. Each commentary is marked out of 14, with an additional 3 marks for portfolio-wide rubric requirements. Thus, the total portfolio score is 45 marks. You must therefore plan each commentary carefully and avoid wasting a single word.
How to Choose the Right Article for Your IB Economics IA
Choosing the right article is arguably the most critical step in the IB Economics IA. First, pick a recent news article from a credible source such as the BBC, Financial Times, or Reuters. Additionally, the article must clearly relate to an economic concept from the syllabus. Avoid articles that are too broad or too short to analyse meaningfully.
For instance, an article on a government sugar tax connects naturally to supply shifts and market failure. Similarly, an article on rising unemployment links clearly to macroeconomic policy tools. Moreover, your teacher must approve the article, so choose strategically. Strong article selection ultimately makes every subsequent step easier.
Assessment Criteria for the Economics IA
Five criteria guide the marking of each Economics IA for IB commentary. Criterion A assesses diagram construction and accuracy. Criterion B evaluates your use of economic terminology. Criterion C focuses on application — how well you connect theory to the article. Criterion D examines the depth of your analysis. Criterion E rewards critical evaluation, such as weighing limitations or alternative views.
Furthermore, you must use one key concept explicitly throughout. Each criterion rewards precision and integration, not length. Therefore, every sentence must serve a clear analytical purpose. Knowing these criteria in advance transforms how you draft and revise your work.
Diagrams in the IB Economics IA: What Examiners Expect
Diagrams carry significant weight in the IB Economics IA. Consequently, you must include at least one fully labelled, accurate diagram per commentary. Every line, intersection, and shaded area must be clearly marked. For example, a supply-demand diagram must show the original and shifted curves, labelled S1, S2, D1, and D2.
Furthermore, each intersection should carry a letter such as E1 or E2. Your diagram must also carry a full title — for instance, “The Market for Petrol in India.” Notably, examiners penalise vague or unlabelled diagrams heavily. Additionally, you must explain in your text exactly what the diagram shows. Therefore, treat diagram and analysis as inseparable.
Tips to Score a 7
Scoring a 7 on the IB Economics Internal Assessment requires both skill and strategy. First, integrate your key concept early and revisit it throughout the commentary. Second, use precise economic vocabulary consistently — avoid casual language. Third, evaluate both sides of an argument rather than simply describing the article.
Additionally, acknowledge real-world limitations of the theory you apply. For example, point out when a model assumes ceteris paribus but real conditions differ. Furthermore, stay tightly within the 800-word limit; quality always beats quantity. Finally, read previous high-scoring IB Economics IA examples to internalise strong commentary structure. Students aiming for top universities like the London School of Economics know that a polished IA signals genuine analytical ability.
Common Mistakes to Avoid
Many students lose marks on the IB Economics IA through avoidable errors. Most commonly, students describe the article rather than analyse it economically. Additionally, some students mention the key concept once without integrating it properly. Others use diagrams that don’t directly relate to the article’s core issue.
Furthermore, exceeding the 800-word limit leads to immediate penalties. Passive description of theory — without linking back to the specific article — also costs marks. Moreover, students often neglect Criterion E by failing to evaluate or challenge their own analysis. Therefore, always review your draft against every criterion individually before submission.
