A CV is the map. A supporting statement is the argument.
Your CV should help someone understand your career, qualifications, skills and achievements quickly. It is usually organised by section: profile, skills, employment history, education and additional details. The reader can scan it in a few seconds and see where you have worked, what you have done and whether your background is relevant.
A supporting statement is more direct. It should respond to the role, the person specification and the essential criteria. Instead of saying, “Here is my career history,” it says, “Here is how my experience proves I can do this job.” That is why the same achievement can appear in both documents without becoming repetition, as long as each version is doing a different job.
For example, your CV might include this bullet:
- Improved appointment booking accuracy by introducing a daily reconciliation check across reception and clinical admin teams.
Your supporting statement might then expand the same evidence:
- In my current healthcare administrator role, I noticed repeated mismatches between booking notes and clinic capacity. I created a daily reconciliation check, agreed the process with reception colleagues and escalated recurring errors to the service manager. This reduced avoidable rebooking issues and gave clinicians more reliable daily lists.
The CV version proves the achievement exists. The supporting statement version explains the context, judgement, action and relevance. That difference matters because some employers score your statement against criteria that are not fully visible in a short CV bullet.
The National Careers Service CV guidance describes a CV as a summary of your skills, achievements and experience used to apply for jobs. Its application form advice also recommends matching your words to the keywords in the job advert so the reader can see why you are a good candidate. Those two ideas sit at the heart of this page: the CV summarises, while the statement matches and explains.
