Start with the person specification
Create a checklist of every essential criterion before you write. Group related criteria where sensible, but do not leave important requirements unanswered. If the employer scores applications, missing evidence can cost you an interview even when your overall background is strong.
Distinguish between criteria asking for knowledge, experience, skill and behaviour. Each type needs slightly different evidence.
Use evidence, not claims
Instead of writing 'I am an excellent project manager', describe a project, the constraints, what you personally controlled, how you handled risks and what happened. Evidence is more persuasive because the recruiter can judge the strength of the example.
A useful structure is context, responsibility, action and result. Keep the emphasis on your decisions and contribution rather than describing the whole team's work.
Match the level of the role
For an officer role, evidence of dependable delivery may be enough. For a manager role, employers may expect planning, prioritisation, people management and accountability. Senior roles may require organisational judgement, governance, budgets and strategic influence.
Choose examples that demonstrate the level at which you can operate, not simply the topic area.
Explain motivation briefly and specifically
A short opening or closing paragraph can explain why the role and organisation interest you. Refer to something real: the service model, strategy, cause, responsibilities or opportunity to apply a particular skill. Avoid making motivation the majority of the statement.
Recruiters still need evidence that you can perform the role.
Use headings when allowed
Headings can make a long statement easier to score. You might group evidence under areas such as programme delivery, stakeholder management, communication and leadership. If the application form provides separate questions, answer the structure it gives you instead.
Keep paragraphs short enough to scan and use bullet points only if the employer's form permits them.
Edit for relevance
Once the first draft is complete, remove anything that does not help prove a criterion or explain motivation. Repetition often appears when the same example is used several times. Where possible, choose different evidence or refer back concisely.
Check word or character limits before drafting so you do not have to cut essential evidence at the last minute.
Frequently asked questions
How long should a supporting statement be?
Follow the employer's stated limit. If none is given, use enough space to address the essential criteria clearly without repeating your CV.
Can I reuse a previous statement?
You can reuse examples, but the structure and emphasis should be rebuilt around the new person specification.
Should I use STAR?
STAR can help structure examples, but write naturally. The reader needs context, your actions and the result more than visible labels.
Recruitment processes vary by employer. Always follow the instructions, essential criteria and deadlines in the specific job advert you are applying for.
