IB Economics IA rubric: five criteria per commentary (14 marks each)

You submit a portfolio of three commentaries, one for each unit — Microeconomics, Macroeconomics, and The global economy — and each commentary must be built around a different key concept. Each commentary is marked out of 14 across five criteria (A–E). The whole portfolio is marked out of 45: three commentaries at 14 marks each (42) plus Criterion F — Rubric requirements (3 marks), which rewards using different units, different sources and articles published within one year of writing.

• Criterion A — Diagrams (3 marks): Correct, clearly labelled diagrams that are directly relevant to the article and fully explained in the text. IBLens checks whether your diagrams are accurate, have all axes and curves labelled, and are genuinely integrated into your analysis.
• Criterion B — Terminology (2 marks): Accurate use of economic terminology throughout. IBLens checks for misused terms, vague language, and missing technical vocabulary.
• Criterion C — Application and analysis (3 marks): Relevant economic theory applied to the article with developed, accurate analysis. IBLens checks whether your analysis explains mechanisms (why and how) and stays focused on the article rather than drifting into generic theory.
• Criterion D — Key concept (3 marks): Identification of one key concept and effective linkage of it to the article. IBLens checks whether a single key concept genuinely frames the commentary.
• Criterion E — Evaluation (3 marks): Judgments supported by reasoned argument — short-run/long-run distinctions, stakeholders, and assumptions. IBLens checks for genuine two-sided evaluation, not just listing pros and cons.

Common IB Economics IA mistakes IBLens catches

• Unlabelled or incorrect diagrams: Missing price/quantity labels, curves not named (e.g., "D1", "D2"), or shifts drawn incorrectly. These mistakes cost marks in every commentary.
• Describing instead of analysing: Explaining what happened in the article without using economic models to explain why or how. Analysis requires you to work through the chain of causation using a diagram.
• One-sided evaluation: Only discussing benefits or only drawbacks. Examiners expect consideration of different stakeholders, time horizons, and limitations of the policy or event.
• Going over the word limit: Each commentary has an 800-word limit (excluding references and diagrams); moderators stop reading at 800 words. IBLens checks approximate word count and flags content that should be cut.
• Weak article-concept link: Using a concept that only loosely relates to the article. The article must be central to your commentary, not just a brief mention in the introduction.
