IB command term
Discuss: what the IB command term asks for
By Michael Thompson - Head of Teaching Excellence; 15 years as an IB Coordinator
In IB exams, discuss means weighing a range of arguments, factors or hypotheses in a balanced way and finishing with a clear conclusion the evidence supports. It asks for an argument between positions, not a description of one of them.
Paraphrased from the command-term definitions in the IB Diploma Programme subject guides (International Baccalaureate Organization).

Judgement and argument
Answer shape: An argument that weighs both sides and commits to a conclusion
What discuss asks for
A discuss question hands you a claim or an issue and expects tension: arguments on one side, arguments or limiting factors on the other, and a writer who weighs them against each other. Every major claim you make needs a counter-claim or qualification set against it, because balance is the point of the command term. The answer ends by committing: a conclusion that takes a position and names why the evidence tips that way, rather than restating both sides and leaving the decision to the reader.
How to structure a discuss answer
Signpost the argument. Open each paragraph with the point it carries, so the structure of the debate is visible at a glance. Attach evidence to claims: an example or study earns its place when it supports the specific argument it sits under, not when it is listed for its own sake. Before writing, the fastest plan is two columns, for and against, filled from everything you can recall; the richer column usually decides your conclusion, and the thinner one tells you which counter-arguments you must still deal with.
Discuss, evaluate or to what extent?
These neighbouring command terms are easy to blur. Discuss wants the debate itself: positions weighed against each other with a supported conclusion. Evaluate leans harder on a verdict about strengths and limitations, and to what extent demands a judgement of degree that you defend from the first paragraph. If you answer a discuss question with a one-sided case, or a to-what-extent question with an undecided survey, markers reward the command term that was actually asked, not the one you answered.
Where it appears
History
History essays use discuss for claims about causes and consequences. Strong answers set perspectives against each other, attach named evidence to each argument, and commit to a weighted judgement instead of narrating events in order.
History tutoringEconomics
In economics, discuss questions usually sit around a policy: build the case for it, the case against it, and the conditions that decide the balance, then conclude for the context in the question rather than in general.
Economics tutoringPsychology
Psychology rewards discussion that weighs supporting and conflicting studies, including their limitations, instead of listing findings. The conclusion should say where the balance of evidence lies and why.
Psychology tutoringBiology
Where biology papers ask you to discuss, they want the factors or interpretations weighed, for example costs against benefits of a process or intervention, with precise terminology and a clear closing position.
Biology tutoringCommon mistakes
- Retelling content without tension between viewpoints: a narrative answer to a discuss question reads as describe and caps your marks.
- Hiding the conclusion: restating both sides in the final paragraph without committing leaves the question unanswered.
- Stacking evidence without arguments: examples only count when each one is attached to the claim it supports.
Frequently asked questions
- Does a discuss answer need my own opinion?
- It needs a supported position. The conclusion should commit to where the evidence points and say why, which is a judgement rather than a personal preference. What it must not do is assert a view the body of the answer never argued for.
- How is discuss different from evaluate in IB exams?
- Discuss centres on the debate: a balanced weighing of arguments with a supported conclusion. Evaluate centres on the verdict: strengths and limitations measured so the judgement itself carries the answer. The overlap is real, but the emphasis differs, and the safest route is to honour the term the paper uses.
