Applying for a government or public-sector role is not the same as applying for a corporate job. The rules are stricter, the process is more structured, and a strong corporate-style cover letter can actually work against you. Public bodies are accountable for hiring fairly, so they score every applicant against a fixed list of criteria. Your letter has one job: prove you meet those criteria with evidence. This guide shows you how.

Why public-sector hiring is different

Corporate recruiters often read on instinct. Public-sector panels do not. They use a competency framework and a person specification, then score each candidate against those points, sometimes numerically. Several people may review your application independently and compare their scores. This means:

• Fair and consistent treatment matters more than charm.
• Every claim usually needs an example to back it.
• Panels look for what is written down, not what they assume you can do.

If a criterion is not clearly addressed in your letter, most panels are instructed to mark it as not evidenced, even if your background obviously covers it.

Mirror the job and person specification

The job advert or person specification is your blueprint. Read it slowly and list every essential and desirable criterion. These are often phrased as competencies such as "manages competing priorities" or "communicates complex information to non-specialists."

• Address the criteria in the same order the specification lists them.
• Reuse the exact wording where it makes sense, so the panel can tick items off quickly.
• Treat essential criteria as non-negotiable. Cover every single one.
• Address desirable criteria too, but do not let them crowd out the essentials.

Panels scan for these terms. If you use different words, you make their job harder and risk losing points.

Prove each competency with a structured example

Do not simply claim a skill. Show it using a situation-action-result structure:

• Situation: the context and the challenge.
• Action: what you personally did, and why.
• Result: the measurable or verifiable outcome.

Keep the focus on "I" rather than "we." Panels score individuals, so they need to see your contribution, not your team's.

A short worked example

Criterion: "Manages competing priorities to meet deadlines."

"In my previous role I was responsible for three concurrent reporting deadlines that fell in the same week. I mapped the tasks against their statutory due dates, negotiated a revised timeline with one internal stakeholder, and delegated data collection to two colleagues with clear checkpoints. All three reports were submitted on time and passed audit review with no corrections required."

Notice that it names the situation, states specific actions, and ends with a verifiable result. That is exactly what a scorer wants to tick.

Get the tone right

Public-sector writing is formal and factual. Avoid marketing hype.

• Say what you did and what happened. Skip words like "passionate," "dynamic," or "world-class."
• Do not use vague buzzwords. "Synergy" and "go-getter" score nothing.
• Be precise with numbers, dates, and outcomes.
• Stay respectful and neutral in tone, even when describing conflict.

Formatting and length

Follow any stated instructions exactly. If the advert asks for two pages, do not send three.

• Typically one to two pages of A4.
• Clear headings, ideally matching the criteria.
• Short paragraphs and, where allowed, bullet points for readability.
• A plain, professional font and standard margins.

If the process uses a separate supporting-statement form, put your evidence there and keep the letter itself brief.

Common mistakes to avoid

• Generic letters: a reused corporate letter that ignores the criteria almost always fails.
• Buzzwords instead of evidence: adjectives do not score; examples do.
• Not addressing every essential criterion: one gap can drop you below the shortlist line.
• Claiming without proving: "excellent communicator" means nothing without a result behind it.
• Ignoring the word or page limit: it signals you cannot follow instructions.

Treat the letter as a scored exam, not a sales pitch. Address every criterion, prove each one with a clear example, keep the tone factual, and you give the panel every reason to shortlist you.
