A practical method for choosing the right evidence, structuring it clearly and using the word limit on the parts that actually score
A good Civil Service behaviour statement is a short piece of evidence, not a description of your personality and not a summary of your job. The assessor needs to see a specific situation, what you were responsible for, what you personally did and what happened as a result.
The first mistake to avoid is assuming every behaviour answer must be exactly 250 words. Many applications use a 250-word maximum, but the vacancy sets the limit. Read the instructions and work to the limit you are actually given.
Need to understand the behaviours first? Start with Civil Service Behaviours: Complete Guide. Want to see finished examples? Go to Civil Service Behaviour Statement Examples.
If the application names a behaviour such as Leadership or Delivering at Pace and asks for an example, this guide applies. If it asks for a personal statement or statement of suitability against essential criteria, use the separate Personal Statement guide instead.
Step 1: Read the behaviour at the correct grade
Do not start writing from the behaviour name alone. Read the grade-level examples in the Success Profiles guidance. The same behaviour changes significantly between AA/AO, EO, HEO/SEO and Grade 6/7.
Underline the actions in the grade description. These are clues to the type of evidence you need. If the description refers to considering risks, involving stakeholders, setting priorities or leading through others, your example needs to show those things through what you actually did.
Use the official Civil Service Behaviours guidance alongside the vacancy.
Step 2: Choose an example with enough evidence
The easiest example to remember is not always the best example to submit. Choose one that gives you something meaningful to explain. A good example normally contains a problem, decision, constraint, disagreement, trade-off or risk. That gives you room to show judgement.
☐ The example clearly matches the behaviour being assessed.
☐ You personally did enough to fill most of the statement with your actions.
☐ The scale and responsibility are believable for the grade.
☐ There was a real choice, challenge or problem to deal with.
☐ You can explain the result without inventing figures.
☐ You can explain why you took the approach you did.
Step 3: Use STAR, with B-STAR only when it earns its space
Official Civil Service candidate guidance suggests STAR as a way to structure behavioural evidence. STAR stands for Situation, Task, Action and Result. Interview Detectives often uses B-STAR, adding a short Belief at the beginning.
The B is optional. It should never become a paragraph of generic claims. If a one-sentence principle helps frame the example, use it. If the word limit is tight, start with the situation and spend the saved words on evidence.
| PART | WHAT IT SHOULD DO | TYPICAL SPACE |
|---|---|---|
| Belief | Optional. One short sentence showing the principle behind your approach. | 0 to 15 words |
| Situation | Give only the context needed to understand the problem. | 25 to 40 words |
| Task | State your responsibility and what had to be achieved. | 15 to 25 words |
| Action | Explain your decisions, reasoning, steps, influence and personal contribution. | 120 to 145 words |
| Result | Show the outcome, impact and any useful learning. | 35 to 50 words |
If you are running out of words, cut background before you cut the explanation of what you did. The assessor cannot give you credit for decisions, judgement or influence that you never describe.
Step 4: Make your personal contribution obvious
Use “I” when you are describing your evidence. “We” can be useful when explaining the wider team context, but the assessor needs to know what you personally decided, changed, checked, challenged, communicated or delivered.
Avoid passive phrases such as “a decision was made” or “a new process was introduced”. Say who made the decision and what you did to get there. If you led through others, describe how you set direction, delegated, challenged or supported rather than pretending you personally completed every task.
Step 5: Explain why you acted, not just what you did
A list of activities can still be weak. Strong behavioural evidence shows your judgement. If you consulted a stakeholder, explain why their input mattered. If you changed the plan, explain what evidence caused the change. If you prioritised one task over another, explain the risk or consequence you were managing.
Could another competent person have followed the same process automatically? If yes, your statement may need more of your judgement. Show where you made a choice, balanced competing considerations or adapted your approach.
Step 6: Show the result properly
The result should tell the assessor why your actions mattered. Figures help when they are real and relevant, but a good result does not need a percentage. You can show improved service, a decision reached, a risk avoided, a deadline met, a stakeholder agreement secured, an error reduced or a team able to work differently because of what you did.
Do not spend 40 words telling the assessor that everyone was delighted. Use the space to state the outcome and, where useful, what you learned or changed afterwards.
Step 7: Calibrate the example to the grade
Grade is not about using more formal language. It is about the level at which you operated. The same project could produce a strong EO example for one person and a strong Grade 7 example for another because their responsibility was different.
| GRADE | CHECK YOUR EXAMPLE FOR |
|---|---|
| AA / AO | Accuracy, ownership of your own work, customer or colleague needs, following and applying guidance, practical problem solving. |
| EO | Independent judgement, ownership of work, coordinating others, proposing improvements, handling a more difficult customer or stakeholder issue. |
| HEO / SEO | Leading activity, wider stakeholders, competing priorities, stronger analysis, recommendations, risk, supporting others to deliver. |
| Grade 6 / 7 | Strategic decisions, senior influence, significant scope, cross-organisational impact, leadership through others, ambiguity, resources and risk. |
Step 8: Write for the application text box
Remember that the Civil Service Jobs application is a text box. Formatting such as colours, tables, bold text and decorative layouts will not carry the statement. Your structure has to work in plain text.
Use clear paragraphs if the form allows line breaks. Do not rely on headings, coloured labels or STAR tags to make the answer understandable. The final version should read naturally as a short piece of evidence.

How to cut a statement to the word limit
Editing down is usually easier when you cut in the right order. Start with anything that does not help the assessor understand the behaviour.
☐ Cut long introductions and generic belief statements first.
☐ Remove background details that do not change the assessor’s understanding of the problem.
☐ Replace job-description wording with the actual action you took.
☐ Remove repeated explanations of the same point.
☐ Keep decision-making, reasoning, personal action and outcomes.
☐ Use shorter wording only after the content itself is right.
Common behaviour statement mistakes
Writing a job description
“I was responsible for…” is context, not evidence. The statement needs one occasion where you actually demonstrated the behaviour.
Choosing a story with no difficult bit
If nothing changed, nobody disagreed, there was no risk and no judgement was required, there may be little for the assessor to score.
Using “we” for every action
The panel cannot tell what you personally contributed.
Forcing every behaviour into one example
The statement is assessed against the behaviour named in the application. Focus the evidence.
Spending half the answer on Situation and Task
Context helps, but the Action section is where your evidence sits.
Inventing a dramatic result
A credible operational improvement beats an implausible claim that your one change saved millions.
Writing above the grade
Adding senior-sounding words does not turn routine evidence into Grade 6 evidence. Use an example with the right responsibility.
Final 250-word behaviour statement checklist

☐ Most of the statement is Action and Result, not background.
☐ The result is specific and credible.
☐ The wording fits within the actual word limit in the vacancy.
☐ The statement still makes sense when pasted as plain text.
☐ I have checked spelling, grammar and names before submitting.

250 Word Behaviour Statement FAQ
Does a Civil Service behaviour statement have to be exactly 250 words?
No. Work to the maximum stated in the vacancy. If the limit is 250 words, you do not need to force the answer to exactly 250, but leaving a large amount of space unused can be a sign that the evidence is too thin.
Should I label Situation, Task, Action and Result?
Usually there is no need. The application box is plain text and the answer should read naturally. STAR is a planning structure, not a requirement to add labels.
Should I include a belief sentence?
Only if it helps. B-STAR is an Interview Detectives approach, not an official requirement. Keep the belief short or drop it when the evidence needs the space.
Can I use the same example for different behaviours?
You can reuse a real situation if different parts genuinely evidence different behaviours. Rewrite the emphasis for the behaviour being assessed instead of submitting the same paragraph unchanged.
Can I use an example from outside the Civil Service?
Yes. The evidence does not need to come from a Civil Service job. It needs to demonstrate the behaviour at the right level.
