What a reference letter is and why it exists

A reference letter is a signed statement in which a referee describes their professional relationship with a person and offers a view on their work, reliability and character. Unlike a pure verification letter, it can include a qualitative assessment as well as the basic facts.

Its purpose is to help a third party — most often a prospective employer — form a fuller picture of a candidate. A fair reference benefits both sides: the candidate gains supporting evidence for their application, and the recipient gains a more rounded basis for a decision.

When it is used

• Supporting a job application, especially at the offer or final stage.
• Applying for further study, training or professional membership.
• Securing a tenancy where a character or employment reference is requested.
• Volunteering or roles that require trusted personal references.
• Confirming suitability after a period of self-employment or a career break.

What a strong reference letter includes

• The referee’s name, role and relationship to the person.
• How long and in what capacity the referee has known them.
• The person’s job title and main responsibilities.
• Specific, fair observations about their work and conduct.
• Relevant strengths illustrated with concrete examples.
• A clear, honest closing recommendation or summary view.
• The referee’s contact details for follow-up where appropriate.
• The date and the referee’s signature.

Common mistakes

• Writing vague praise with no specific examples to support it.
• Including misleading or exaggerated claims the referee cannot stand behind.
• Straying into protected personal characteristics rather than work and conduct.
• Providing a reference without the person’s knowledge or consent.
• Copying generic wording that could apply to anyone.
• Forgetting to date or sign the letter.

Good practice

• Keep comments fair, accurate and based on first-hand experience.
• Focus on the role and conduct rather than personal matters.
• Use concrete examples to make the assessment credible.
• Confirm with the person what the reference is for before writing it.
• Share the finished letter as a tidy, signed PDF where a hard format helps.
