A professional recommendation is most useful when it helps a hiring manager or selection committee predict how the candidate will perform in the new context. Titles and compliments matter less than credible evidence of responsibility, judgment, results, and the way the person works with others.
Busy managers can write a strong letter quickly by identifying the destination, defining the reporting relationship, and choosing two examples that show both performance and professional character.
Start with the target role
Ask for the job description, promotion criteria, leadership competencies, or appointment brief. A general letter may still be useful, but a targeted letter can explain why the candidate’s demonstrated work transfers to the responsibilities ahead.
Do not claim expertise about a role you do not understand. Focus on the behaviors and results you observed, then connect them conservatively to the destination.
Establish your working relationship
- Your title and relationship to the candidate.
- How long and how closely you worked together.
- The candidate’s responsibilities and level of autonomy.
- The size, complexity, or stakes of the work when relevant.
- Whether you directly supervised the results you describe.
Choose two examples with business meaning
One example might demonstrate execution: improving a process, resolving a customer problem, completing a difficult analysis, managing a deadline, or taking ownership when a plan failed. A second might demonstrate leadership or collaboration: aligning stakeholders, coaching a colleague, communicating risk, or raising an ethical concern.
Use numbers when you know them and they are appropriate to disclose. Explain the candidate’s contribution rather than attributing an entire team result to one person.
Translate strengths into observable behavior
- Instead of “strategic,” describe the tradeoff the candidate recognized and the decision they recommended.
- Instead of “excellent communicator,” describe the audience, message, and resulting alignment or action.
- Instead of “natural leader,” describe how the candidate created clarity, accountability, or confidence for others.
- Instead of “reliable,” identify the recurring responsibility they handled without avoidable follow-up.
Protect confidential and sensitive information
Do not disclose proprietary data, protected customer information, private personnel matters, medical information, or details you are not authorized to share. A useful example can often be written at the level of the decision and behavior without revealing restricted facts.
Follow your employer’s current reference policy. Some organizations limit who may provide references or what information may be included.
Close with a clear professional judgment
State whether you recommend the candidate and for what kind of responsibility. If you would hire or work with the person again, say so only when true. Offer professional contact information and avoid promises about performance that extend beyond your evidence.
A professional recommendation should make future performance easier to predict. Define the relationship, show two consequential behaviors, protect confidential information, and state your judgment clearly.
