What Is a Person Specification? 11 Steps to Understand & Use It

If you've ever applied for a job — especially in the NHS or public sector — you've probably seen something called a person specification. But what exactly is it, and why does it matter so much?

Understanding what a person specification is represents one of the most important steps in improving your job applications. In simple terms, a person specification is a checklist of the skills, experience, qualifications, and personal qualities an employer is looking for in a candidate.

And here is the key: most hiring decisions — shortlisting and interviews — are based directly on it.

What Is a Person Specification?

A person specification is a document that outlines what an employer is looking for in a candidate. It usually sits alongside the job description and focuses on the type of person needed for the role. Think of it as a checklist — it lists the skills, experience, qualifications, and personal qualities the employer considers essential or desirable.

Simple definition

A person specification is a list of criteria that describes the ideal candidate for a job. These criteria typically include:

• Qualifications
• Work experience
• Skills
• Knowledge
• Personal qualities

Where you find it

You will usually find the person specification:

• In the job advert itself
• Attached as a separate PDF
• Inside or alongside the job description
• On the employer's recruitment portal

In NHS roles, it is often clearly structured and labelled. If you cannot find it, contact the employer and ask. Never apply without reading it first.

Why a Person Specification Is Important

Understanding the person specification is essential because it is how employers compare candidates fairly and consistently.

How employers use it

Recruiters use the person specification to:

• Shortlist candidates against specific criteria
• Score each application line by line
• Structure interview questions around key requirements
• Make fair, evidence-based hiring decisions

If your application does not clearly show how you meet the criteria, you may not be shortlisted — even if you are qualified for the role.

How candidates should use it

As a candidate, the person specification is your single best preparation tool. Instead of guessing what matters, you follow exactly what the employer is asking for. You should use it to:

• Tailor your CV to highlight relevant experience
• Write a strong supporting statement that addresses every criterion
• Prepare interview answers around the key requirements
• Identify gaps in your experience before you apply

Key Sections of a Person Specification

Most person specifications are broken into clear sections.

Qualifications

This includes required education or certifications, such as:

• Required degrees or diplomas
• Professional registrations (e.g. NMC, HCPC)
• Training courses or certifications

Experience

This section covers:

• Previous roles in similar settings
• Relevant work environments (e.g. healthcare, admin)
• Specific responsibilities (e.g. patient contact, data handling)

Example: "Experience working in a healthcare environment" means any setting where you worked with patients, clinical staff, or health-related services.

Skills and knowledge

This might include:

• Communication skills (written and verbal)
• IT skills and systems knowledge
• Knowledge of relevant processes or legislation

Personal attributes

These are behavioural qualities such as:

• Teamwork and collaboration
• Compassion and empathy
• Reliability and attention to detail
• Flexibility and resilience

Personal attributes are especially important in NHS roles. Panels want to see these demonstrated through real examples, not just listed as adjectives.

Essential vs Desirable Criteria Explained

This is one of the most important distinctions in any person specification.

Essential criteria are requirements you must meet to be considered for the role. Desirable criteria are bonus qualities that can strengthen your application but are not mandatory.

Focus first on essential criteria — that is what gets you shortlisted. Only address desirable criteria after you have fully covered every essential requirement. Missing even one essential criterion can mean automatic rejection.

How to Read a Person Specification Properly

Do not just skim it — break it down systematically. This turns the document from a wall of text into a clear action plan.

• Highlight all essential criteria first
• Identify repeated themes (e.g. communication, teamwork)
• Note the specific keywords used
• Match each point to your own experience
• Flag any gaps you need to address

The keywords in the person specification are often the same keywords the panel will use in interview questions. Preparing around them means you are preparing for both the application and the interview at the same time.

How to Match Your Experience to a Person Specification

This is where many applicants struggle. Instead of listing your experience randomly, you should align it directly with each requirement.

Use a simple mapping approach: for each requirement in the person spec, identify a specific example from your experience that demonstrates it. The strongest applications address every essential criterion with a specific, real example — not a vague statement.

For example:

• Communication skills → A specific example from your work
• Teamwork → A real situation where you collaborated
• Organisation → A task or process you managed effectively

Common Mistakes to Avoid

These are the errors that cost candidates shortlist places — even when they are qualified for the role.

• Ignoring the person specification — many candidates never read it properly. This is the number one reason for rejection.
• Writing generic applications — if your application could work for any job, it is not tailored enough.
• Not covering all essential criteria — missing even one essential criterion can mean automatic rejection.
• Listing skills without examples — saying "I am a good communicator" without evidence is not enough. Show it.
• Focusing too much on desirable criteria — cover all essentials first. Desirables are bonus points, not the priority.

Example of a Person Specification

Here is a simplified example for an NHS administrative role:

Essential:

• Good written and verbal communication skills
• Experience working in a team environment
• Basic IT knowledge (email, Word, spreadsheets)
• Ability to handle confidential information
• Good organisational and time management skills
• Compassionate and respectful approach

Desirable:

• Previous NHS or public sector experience
• Knowledge of medical records systems
• Experience using appointment booking software

Your job is to prove each essential point with evidence from your experience. Address every single one — missing even one can mean rejection.

How It Helps with Supporting Statements & Interviews

The person specification is not just for your application — it is your interview preparation guide too.

Supporting statements

Structure your statement around the criteria. Address each essential point with evidence and use the same keywords the employer used.

Interview preparation

Most interview questions come directly from the person specification. If you prepare using the person spec, you are preparing for the interview at the same time. The panel will ask about the same themes.

Prepare STAR examples for each key criterion, and anticipate values-based questions from the attributes section.
