Supporting statement vs personal statement vs cover letter: what is the difference?
Updated · By the Tick the Spec team
A cover letter introduces you and your interest in a job; a supporting statement proves, criterion by criterion, that you meet the person specification; and a personal statement is the name some employers, especially the Civil Service and universities, use for a supporting statement. In UK public sector recruitment, the employer usually scores the statement against the criteria, so a classic private-sector cover letter often scores poorly. If the advert asks for a statement, write to the criteria. If it asks for a cover letter, still evidence the key criteria, just more briefly.
The three documents side by side
| Cover letter | Supporting statement | Personal statement | |
|---|---|---|---|
| Main purpose | Introduce you and invite the reader to look at your CV | Evidence each criterion in the person specification | Usually the same as a supporting statement; in the Civil Service, evidence of the experience and skills in the advert |
| Typical users | Private sector, some charities and smaller organisations | NHS ("supporting information"), councils, universities, schools, police staff | Civil Service, universities, some councils; also used for university admissions (a different thing) |
| Length | About one page | Set by the form or advert; often one to two pages where there is no limit | Often a word limit in the advert, for example 500, 750 or 1,250 words |
| Structure | Opening, why this role, two or three highlights, close | Short opening, then one section per criterion in the person specification's order | Follows the criteria listed in the advert; headings often help |
| How it is read | Often skimmed alongside the CV | Scored line by line against criteria | Scored against the criteria in the advert, sometimes on a numeric scale |
When the advert says "cover letter" but means a statement
Some public sector adverts ask for a "covering letter" that "explains how you meet the person specification". That is a supporting statement in letter form. Keep the letter format (greeting, sign-off), but inside it address the criteria in order, with evidence for each. If in doubt, follow the wording of the instructions, and contact the recruiting manager if the advert gives a name.
When the form has separate boxes
NHS Jobs, for example, asks for supporting evidence in boxes for qualifications and experience, plus any additional criteria the employer adds, each with an essential and a desirable box. Here you are not writing one flowing document; each box should evidence the criteria under that heading. See how to fill in the NHS Jobs criteria boxes.
Civil Service personal statements
In Civil Service applications the personal statement is usually assessed against the experience, skills or behaviours listed in the advert, within a word limit. It is not a description of your personality or career ambitions. Our Civil Service personal statement guide covers structure and scoring.
Worked example: the same evidence written two ways (fictional)
Invented applicant and employer. Jamal is applying for a Research Administrator post at a university. One essential criterion is "Experience of organising meetings and events, including managing bookings and budgets".
As a cover letter paragraph:
I am a highly organised administrator with a passion for supporting academic research. In my current role I organise a wide range of meetings and events, and I would bring this experience to your department.
This reads well but gives the panel nothing to score: no example, no budget, no result.
As a supporting statement section:
Experience of organising meetings and events, including managing bookings and budgets. In my current role at a professional membership body I organise around 30 meetings a year and two annual conferences. For last year's regional conference of 120 delegates I booked the venue and catering, managed a budget of £8,000, and tracked spending in a shared spreadsheet that I updated weekly for my manager. When the caterer raised prices six weeks before the event, I compared two alternatives, negotiated a smaller menu with the original supplier, and stayed within budget. Feedback scored the organisation 4.6 out of 5.
The second version names the criterion, gives a specific example with scale, budget and a problem solved, and ends with a result.
Common mistakes
- Sending your standard cover letter to a public sector job that asks for a statement.
- Repeating your CV line by line instead of picking examples that match each criterion.
- Writing about your personality in a Civil Service personal statement instead of evidence.
- Ignoring the format asked for: upload versus text box, word limits, headings.
- Overusing "passionate" and other words that are not evidence.
Whatever the document is called, the panel will be checking it against the criteria. Tick the Spec's free shortlisting sheet shows which criteria your CV already evidences, so you can focus your statement where it matters. Next, read how to write a supporting statement.
