IB Command Terms Explained

Decode what examiners expect from every IB command term - essential knowledge for exam success.

Command terms are the verbs in exam questions that tell you exactly what examiners expect. Understanding the difference between 'describe' and 'explain', or 'analyse' and 'evaluate', is crucial for exam success. Many students lose marks not because they lack knowledge, but because they misinterpret what the question is asking. Our command term guides break down each term with examples, structures, and subject-specific applications to help you maximise your exam marks.

Key Takeaways

  • The command term tells you what to do with your knowledge
  • Terms such as evaluate, discuss and to what extent require a judgement; analyse asks you to break something down
  • Check the mark allocation - more marks means more development expected
  • Practise with past papers and study markscheme expectations
  • Misinterpreting a command term costs more marks than knowledge gaps

Frequently Asked Questions

Command terms tell you exactly what the examiner wants. Using the wrong approach - like describing when asked to evaluate - loses marks even if your content knowledge is correct. Understanding command terms is often the fastest route to grade improvement.

The IB defines command terms consistently, but application varies by subject context. 'Evaluate' means the same thing conceptually, but what you evaluate differs in History vs Biology. Learn the core meaning, then apply in context.

Do past paper questions, paying close attention to command terms. After answering, check markschemes to see if your approach matched expectations. Notice patterns in how different terms require different responses.
