In the International Baccalaureate (IB) Economics syllabus, command words are not just suggestions—they are strictly categorized into four Assessment Objectives (AOs). Treating an AO2 command term like an AO3 command term is the fastest way to cap your Paper 1 essay at a Level 5.
To secure a Grade 7, you must dissect the prompt exactly as the IBO intends. Here is definitive, comprehensive guide to IB Economics Command Terms that all students of our IB Economics Tuition programme will be guided to master.
AO1: Knowledge and Understanding (The Basics)
These terms require you to demonstrate fundamental knowledge. They appear frequently in Paper 2 data response questions.
- Define: Give the precise meaning of a word, phrase, or concept. (No need for examples or diagrams here—just the exact definition.)
- Describe: Give a detailed account of a pattern or trend.
- State: Give a specific name, value, or other brief answer without explanation.
AO2: Application and Analysis (Paper 1 part A, Paper 3)
These terms require you to use economic theories and apply them to Real-World Examples (RWEs).
- Explain: Give a detailed account including reasons or causes. (Crucial for your 10-mark Paper 1 Part A essay. Use a diagram and a hypothetical example to show exactly how a theory works.)
- Distinguish: Make clear the differences between two or more concepts.
- Calculate: Obtain a numerical answer and show your working.
AO3: Synthesis and Evaluation (Paper 1 Part B & Paper 2)
This is the highest level of cognitive demand. These terms carry the bulk of your marks in Part B (15 marks) and require our proprietary CLASPP evaluation framework.
| Command Term | Official IB Definition | How to Execute It |
|---|---|---|
| Discuss | Offer a considered and balanced review of a range of arguments. | Look at multiple angles. Support your opinions with evidence and Real-World Examples. Ensure you cover both pros and cons. |
| Evaluate | Make an appraisal by weighing up strengths and limitations. | Explicitly state the theoretical benefits of a policy, followed by its real-world limitations (e.g., ceteris paribus assumptions, time lags). |
| To what extent | Consider the merits or otherwise of an argument. | Make a definitive, justified judgment in your conclusion. State clearly how much you agree with the premise based on your preceding evidence. |
AO4: Use and Application of Appropriate Skills
These terms dictate how you use your mathematical and diagrammatic tools.
- Draw: Represent by means of a labelled, accurate diagram or graph, using a pencil.
- Derive: Manipulate a mathematical relationship to give a new equation.
