IB Economics IA rubric: five criteria (45 marks total)

Each IB Economics IA commentary is marked out of 45 marks across five criteria. You submit three commentaries, each on a different section of the syllabus (Microeconomics, Macroeconomics, International Economics, or Development Economics).

• 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 (3 marks): Accurate use of economic terminology throughout. IBLens checks for misused terms, vague language, and missing technical vocabulary.
• Criterion C — Application (3 marks): Effective application of economic concepts to the real-world article. IBLens checks whether your analysis stays focused on the article rather than drifting into generic theory.
• Criterion D — Analysis (5 marks): Depth and accuracy of economic analysis including relevant theory, models, and cause-and-effect chains. IBLens checks whether your analysis explains mechanisms (why and how) rather than just describing what happens.
• Criterion E — Evaluation (5 marks): Balanced, well-supported evaluation with short-run/long-run distinctions, stakeholder analysis, and limitations. 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 a 750-word limit (excluding references and diagrams). 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.
