AO4 Evaluation: Why a Conclusion Must Do More Than Repeat
By the time most students reach the conclusion of an essay, they’ve run out of time, ideas or confidence. So they do what feels safe: they summarise what they’ve already written.
“In conclusion, raising prices has advantages and disadvantages. It could increase revenue, but it could also lose customers.”
It feels like a conclusion. But it earns very few evaluation marks, because it doesn’t decide anything.
Evaluation, known as AO4, is the assessment objective that separates A and A* students from everyone else. This page explains what examiners are really looking for, how many marks are at stake, and how we teach students to write conclusions that make a decision, solve the problem and show what that decision depends on.
What is AO4?
AO4 is the skill of making a judgement. According to Ofqual’s definition, students must evaluate evidence to make informed judgements and propose evidence-based solutions to business issues.
That means a strong conclusion should:
Answer the question directly.
Should the business do it or not? To what extent is the statement true?
Justify the decision.
Explain which argument is strongest and why it outweighs the others.
Identify what it depends on.
Recognise the key factors that could change the answer.
Offer a solution or alternative.
Explain what the business should actually do, including options it may not have considered.
If AO1 asks “What is it?”,
AO2 “What does it mean for this business?”
and AO3 “What happens next?”,
then AO4 asks “So what should the business do, and why?”
How many marks is AO4 worth?
Across all exam boards, evaluation is worth roughly a quarter of the total marks:
| Exam board | AO4 weighting (approx.) |
|---|---|
| AQA (exams up to 2027) | 23–26% |
| AQA (new specification, first taught Sept 2026) | 24% |
| Edexcel | 26–28% |
| OCR | 25% |
But that overall figure hides how important evaluation is on the questions that matter most. On an AQA 25-mark essay, 10 marks are for evaluation, more than any other skill. On an OCR 15-mark question, it’s 7 marks out of 15.

These long questions are where the highest grades are decided. A student who writes excellent analysis but a weak conclusion can lose a large share of the marks on every essay, which is often the difference between a B and an A*.
The “repeat” conclusion, and what to do instead
Let’s finish the Harper’s Bakery case study. Harper’s is the family-run bakery with three shops and loyal daily customers, now facing a new discount chain on the same high street. It is considering a 10% price rise.
A weak conclusion: repeating the essay
“In conclusion, Harper’s should raise its prices because demand is inelastic, so revenue will increase. However, the discount chain might take some customers. Overall, there are advantages and disadvantages.”
Every sentence repeats something already said. There’s no clear decision, no explanation of which argument matters most, and no guidance on what Harper’s should actually do. “Advantages and disadvantages” is not a judgement.
A strong conclusion: judging, depending, solving
“Overall, Harper’s should raise prices, but not across its whole range. The strongest argument for the rise is its loyal customer base: with around 70% of sales from daily regulars, demand for its signature products is likely to remain price inelastic. However, this depends on how directly the new discount chain competes. Price-sensitive customers buying basic items, such as standard loaves, are most likely to switch, while customers buying Harper’s specialist bakes are less likely to.
A better solution would be to raise prices by 10% on its specialist products, where Harper’s has a clear point of difference, while holding prices on everyday basics to protect footfall from the new competitor. Harper’s could also introduce a loyalty scheme to reward its regulars and make switching less attractive. In the short term, this protects revenue; in the long term, it depends on whether Harper’s can keep its quality and service ahead of a cheaper rival.”
This conclusion doesn’t repeat the essay. It:
- makes a clear decision: raise prices, but selectively;
- justifies it with the strongest argument from the case study;
- identifies what it depends on: how closely the discount chain competes;
- proposes a solution: a targeted price rise plus a loyalty scheme;
- considers alternatives: selective rather than blanket pricing;
- distinguishes the short term from the long term.
Our conclusion framework
We teach students a simple structure they can use in any exam, for any question:
Judge.
Answer the question directly in the first sentence. No sitting on the fence.
Justify.
Explain which argument is the strongest, and why it outweighs the others.
Depends.
Identify the key factor (or two) that could change the answer.
For example: “This depends on…”, “unless…”, “provided that…”Solve.
Recommend what the business should do: a specific solution, an alternative option, or a way to reduce the risks raised in the essay.
Students also learn useful evaluative angles that help them go beyond repetition:
Why knowledge, application and analysis are the essential prerequisites
Evaluation is the final layer of the answer, and it’s only as strong as what it’s built on.
Knowledge lets students see alternative options.
A student who knows about loyalty schemes, price discrimination and product differentiation has more solutions to recommend.
Application makes judgements specific.
“It depends on the competition” is generic; “it depends on how directly the discount chain competes on basic products” is evaluation.
Analysis provides the evidence for the decision.
Examiners reward judgements that link logically to the arguments in the essay. A conclusion that appears from nowhere, or contradicts the analysis, won’t reach the top level.
That’s why our approach builds through all four assessment objectives in order, from AO1 Knowledge and Understanding to AO2 Application and AO3 Analysis.
How we develop evaluation skills in lessons
We ban “advantages and disadvantages”
We challenge students whenever a conclusion sits on the fence. “It has pros and cons” isn’t an answer. We ask: “So, should they do it or not? Why? What would change your mind?”
We practise “it depends on…”
For every decision, we ask students to name the one factor that matters most. How big is the budget? How strong is the competition? What are the owner’s objectives? Over time, identifying dependent factors becomes instinctive.
We generate alternatives
Before writing a conclusion, students brainstorm at least two alternative options the business could take, beyond the ones in the question. This turns conclusions from summaries into solutions.
We rank arguments
Students rank the arguments from their essay from strongest to weakest and justify the order. Deciding what matters most is the core of evaluation.
We rewrite weak conclusions
We take “repeat” conclusions, whether the student’s own or examples we provide, and rebuild them using the Judge, Justify, Depends, Solve framework. Every improvement is highlighted in a different colour in the shared Google Doc, so students can see how the conclusion develops from first draft to top-level answer.
We use mini-judgements throughout
Evaluation doesn’t have to wait until the end. We teach students to weigh up each argument as they go, with a short sentence on how significant it is. This way, the final conclusion builds naturally on judgements already made.
We think like decision-makers
Using real business news, we ask students what they would do if they ran the business, and to defend that decision under questioning. It builds the confidence to commit to a judgement in the exam.
How we develop evaluation skills through homework
Conclusion-only practice.
Students are given a question and a plan of the arguments, and write only the conclusion. This targets the skill directly without the time cost of a full essay.
“What would you do?” business news.
Each week, students read a story about a real business decision and write a short recommendation: what the business should do, why, and what it depends on.
Alternative options lists.
For each topic, students build a bank of alternative strategies a business could use, ready to draw on in exam conclusions.
Timed full essays.
Regular timed essays marked against the mark scheme, with particular focus on whether the conclusion judges, justifies, identifies dependent factors and solves.
Self-check before submitting.
Students reread their conclusion and ask: “Have I made a decision? Have I said what it depends on? Have I told the business what to do? Have I said anything new?”
How you can help at home
Evaluation is about making decisions and defending them, something you can practise over dinner. Ask your son or daughter questions like:
Then push back gently. If they can defend their decision, explain what it depends on and suggest an alternative, they’re thinking like an evaluator.
The final step to the top grades
Evaluation brings everything together: knowledge to see the options, application to make them specific, analysis to provide the evidence, and judgement to decide. When a student can write a conclusion that makes a clear decision and solves the business’s problem, they’re ready to access the highest marks.

FAQs
Why does my child lose marks in their conclusion when they’ve summarised their essay well?
Because summarising isn’t evaluating. Examiners want a clear judgement, an explanation of what that judgement depends on, and ideally a solution. Repeating earlier points adds nothing new, so it earns little credit.
Is it OK to say “it depends”?
Yes, but only if the student explains what it depends on and why, and still reaches a decision. “It depends” on its own is sitting on the fence.
Does evaluation only happen in the conclusion?
No. The strongest answers weigh up arguments throughout, with short judgements after each point. The final conclusion then brings those judgements together into an overall decision.
