Personal statement or behaviour statements: which does your advert want?
Some adverts want one statement against all criteria. Others want separate behaviour boxes. Here is how to tell which yours wants, and why it matters.
Two candidates can face the same advert and write two completely different applications, both wrong for different reasons. One writes a single flowing account of their career and pastes it into a form that actually wanted four separate boxes, one per Behaviour. The other writes four tight, isolated examples and submits them where the advert wanted one joined-up case against the essential criteria as a whole.
Neither candidate has bad examples. They have the wrong shape. A sift panel scoring a form field by field cannot go looking for evidence that got left in the wrong box, and a panel expecting one coherent case cannot credit four fragments that never add up to anything.
This post is about working out which shape your advert wants before you start writing, why the two genuinely require different writing, and what to do on the campaigns that ask for both.
How can you tell whether your advert wants a personal statement or behaviour statements?
You look at two things: the advert’s assessment section, and the application form itself. GOV.UK’s own guidance to candidates confirms that “details of which elements will be assessed and how we will assess you are included in the job advert” (gov.uk). That line is doing more work than it looks like. It means the advert, not a general rule about how Civil Service applications work, is what tells you the shape of the writing task in front of you.
Before you open the form, that is the job: work out what your advert is asking for. Read the “how we will assess you” or “how to apply” section for the words “personal statement”, “supporting statement” or “behaviour” appearing as separate labelled fields. Then open the application form itself, because the form is the definitive answer. If it presents one large free-text box against the essential criteria, that is a personal statement or supporting statement. If it presents several smaller boxes, each headed with the name of a named Behaviour and each carrying its own word count, that is a set of behaviour statements. Some forms show both, plus a CV upload. Nothing about your grade, your department or your previous applications tells you which one you are looking at. Only this advert does.
What is a personal statement actually asking you to write?
It is asking for one joined-up case that covers the essential criteria as a whole, not a Behaviour at a time. GOV.UK’s Success Profiles guidance describes this route plainly: candidates “may be asked to submit a CV (and sometimes a supporting statement) as well as, or instead of, an application form”, and that a supporting statement should “further highlight how you meet the essential criteria required to do the role” (gov.uk). Some adverts call this a personal statement, others a supporting statement or statement of suitability. The label varies by campaign. The job does not: you are building a single piece of connected prose that argues, criterion by criterion, why you meet the role, and you get to decide how the paragraphs flow into each other.
That connectedness is the whole point of the format. A strong personal statement can let one example do double duty, showing judgement for one criterion and initiative for another in the same story, because nothing about the format forces you to keep your evidence in separate compartments. If you only partly meet one of the essential criteria, that gap does not disappear just because it is sitting inside a paragraph rather than a labelled box. It still needs addressing directly, which is its own problem worth solving properly rather than hoping the surrounding prose will carry it.
What are behaviour statements asking you to do instead?
They are asking for discrete, self-contained evidence against one named Behaviour at a time, with no expectation that the boxes talk to each other. Most application forms that use this route give you a separate free-text field per Behaviour, and each one has its own limit: the Civil Service Jobs application form “will automatically delete any words which exceed the 250 allowed for each example” (gov.uk). Go five words over and the system silently cuts your sentence off mid-thought, not politely, not with a warning you will necessarily notice before you submit.
Success Profiles guidance recommends structuring each example with the STAR method, so that you “set the scene, show what and how you did and the overall outcome” (gov.uk). Notice what that structure does not include: a bridge to your other examples, a running theme across the form, or a reference back to something you said in a different box. Each behaviour statement has to stand on its own, prove one Behaviour at the level the advert names, and do it inside a strict word count with nothing spare for context that belongs somewhere else.
Why does the split into separate boxes matter for how you get scored?
Because the sift, in GOV.UK’s own words, is “an assessment of your behaviour examples, CV and personal statement and other criteria to determine whether they are sufficient to merit you being invited to interview” (gov.uk), and it names behaviour examples and a personal statement as separate, distinct things a sift can draw on. The same guidance states that “generally to progress to the next stage a candidate should score at least 4 for each example” (gov.uk), against a seven-point scale. For each example is doing the work here. It reads as though a behaviour example gets its own mark, not a share of one combined impression across the whole form.
That is the safest working assumption for a form built around separate behaviour boxes, and it is worth explaining why it is only an assumption rather than a stated universal rule. GOV.UK’s guidance says “generally”, not “always”, and it does not spell out, campaign by campaign, whether every panel marks every box in strict isolation or whether some campaigns take a rounder view across the whole application. Practice can vary. What does not vary is the practical risk: if a panel member opens your Working Together box looking for evidence of working together, and the only mention of it is buried in your Communicating and Influencing example three fields away, there is nothing built into the form that sends them looking for it. PublicServicePathway is independent of the Civil Service, and this is our reading of how the form is built to be marked, not a claim about how every panel on every campaign actually behaves. Write to the safer assumption regardless, because the cost of being wrong runs only one way. A self-contained example that also reads well as part of a bigger picture loses nothing. A scattered one that depends on the reader connecting boxes loses marks with no way to know it happened.
What actually goes wrong when you write one long narrative into a form that wanted separate boxes?
Your best evidence ends up sitting behind the wrong label, and a sifter working through named boxes has no reason to go looking for it elsewhere. Say the form asks for Making Effective Decisions in one box and Delivering at Pace in another. A candidate who is used to writing a single flowing personal statement often drafts one strong story and then tries to split it in half down the middle, so half the story sits in each box. The result is two thin fragments, neither of which reads as complete evidence of anything, because the situation, the action and the result were built to work together and do not survive being cut in two.
The reverse mistake looks different but costs just as much. A candidate who has practised writing tight, isolated behaviour examples brings that same instinct to a personal statement, and produces four short, unconnected paragraphs, one per criterion, with nothing joining them. A personal statement read like that reads as a checklist rather than a case, and a checklist under-uses the one advantage the format actually gives you: the chance to let a strong example carry weight across more than one criterion at once, in your own words, in your own order.
What do you do when the advert asks for both a personal statement and behaviour statements?
You split your evidence deliberately rather than letting it land wherever you wrote it first. Some campaigns genuinely ask for a CV, a personal statement or supporting statement, and separate behaviour examples in the same application, because different assessment methods can test different Success Profiles elements, and “more than one element may be tested within the same assessment method” only tells you they can overlap, not that they must repeat (gov.uk).
Work out first which examples are strong enough to be your named behaviour evidence, and put your best, cleanest, most self-contained version of each of those into its box. Then, when you write the personal statement, choose different material where you have it, or take the same episode from a genuinely different angle if you do not. If your best story for Making Effective Decisions is already doing full-length work in its own box, do not retell it start to finish again in the statement. Reference the outcome in a single sentence if it is genuinely relevant to a wider point you are making about your suitability, and spend the rest of the statement’s word count on evidence the behaviour boxes never got to use. A panel reading both documents will notice a candidate who found more than one story to tell faster than they will credit one good story told twice.
FAQ
Can the same example appear in both a personal statement and a behaviour statement on the same application? It can, but repeating it word for word wastes the space you have been given. Use a different angle, a different part of the outcome, or genuinely different evidence in the second document, so the panel is reading something new rather than a duplicate.
Does every Civil Service advert use one format or the other, never both? No. Some ask for only a personal statement, some for only behaviour examples, and some for a CV plus both. The advert and the form are what tell you which combination applies to your application.
Is a personal statement and a supporting statement the same thing? Functionally, yes. Different campaigns use different labels for the same free-text case against the essential criteria as a whole. Check the form itself rather than relying on the label in the advert.
What happens if I go over the word limit on a behaviour statement? On the Civil Service Jobs application form, any words over the 250 allowed for each example are automatically deleted, which can cut a sentence off mid-thought without warning.
Do behaviour statements always need the STAR method? Success Profiles guidance recommends it as a way to structure the example clearly, covering the situation, your action and the outcome, but the form itself is what states any requirements specific to your campaign.
Get the rest of your application right for the format you are using
Once you know which shape your advert wants, the next job is making sure every piece of evidence earns its place, whichever box it sits in. Start by reading your own advert’s assessment section again with this distinction in mind, then turn what you find into a plan before you draft a single sentence.
