How to Write a Reference Letter in 2026

March 29, 20265 min

A strong reference letter can tip the scales for a candidate. It provides a credible external perspective on skills and character. Here's how to write one that truly makes a difference.

Who Should Write It?

Ideally, a direct supervisor, professor, or client who worked closely with the person. The author's credibility matters as much as the content itself.

The Ideal Structure

  • Introduction: who you are and your relationship with the candidate
  • Context: duration and nature of the working relationship
  • Key qualities: 2-3 skills backed by specific examples
  • Achievements: measurable results the candidate delivered
  • Closing: explicit recommendation and your contact details

What to Avoid

  • Vague praise ("good team player", "hard worker")
  • Letters that are too short or generic
  • Exaggerations that undermine credibility
  • Irrelevant personal information

Make It Specific

Tailor each letter to the target role. Use numbers when possible: "increased sales by 25%" is far more convincing than "achieved good commercial results."
