How to Write a Reference Check Response for a Former Colleague in English

Being asked for a reference is a compliment, but it’s also a specific writing task with its own conventions in English: concrete over vague, honest over glowing, and tactful when a weakness needs to be mentioned at all. Generic praise (“she’s great, hire her”) is often read as a weak reference, since it suggests you have nothing specific to say.

Key Vocabulary

Specific example over general praise — backing a claim about someone’s skill with a concrete situation, rather than an adjective alone, because specifics are what make a reference credible. “Rather than just saying he’s a strong communicator, I gave a specific example: he ran the migration announcement to the whole engineering org and fielded questions live without getting defensive.”

Contextualizing a weakness — mentioning a genuine area for growth in a way that’s honest but framed constructively, usually paired with evidence of improvement or a mitigating factor. “I contextualized the weakness: early on, her estimates ran optimistic, but by the second half of the project she was building in buffer time and her estimates became reliable.”

Scope of working relationship — stating clearly how, and for how long, you worked with the person, so the reader can calibrate how much weight to give your account. “I opened with the scope of our working relationship: we were on the same team for two years, and I was her tech lead for the last eight months of that.”

Declining to comment — a professional way to say you can’t speak to something, without implying something negative by your silence. “On the compensation question, I have to decline to comment — that wasn’t something I had visibility into.”

Common Phrases

• “I worked directly with [name] for [duration], as their [role relationship].”
• “One thing that stood out about their work was [specific example].”
• “If I had to name an area for growth, it would be [X], though I saw real progress on this over time.”
• “I’d hire them again without hesitation.”
• “I’m not the right person to speak to [specific area] — you might ask [alternative contact] instead.”

Example Sentences

Opening with scope and relationship: “I was [name]‘s manager for just over a year, on the platform team, and worked with them closely on two major migrations during that time.”

Giving a specific, credible strength: “What stood out most was how she handled an on-call incident during her first month — she paged the right people quickly, kept a clear timeline, and didn’t try to solve it alone when it was outside her expertise.”

Handling a weakness honestly but fairly: “If I’m being candid, written documentation wasn’t his strongest area early on — code comments and PR descriptions were often thin. That said, he took feedback on this well and it visibly improved over the months I worked with him.”

Closing with a clear recommendation: “My honest assessment: I’d welcome the chance to work with them again, and I think they’d do well in a role with more ownership than they had with us.”

Professional Tips

• Replace general adjectives (“great,” “amazing”) with specific examples — vague praise is often read as a soft decline.
• If asked about a weakness, be honest but pair it with context or growth — refusing to name any weakness at all can read as evasive.
• State the scope of your working relationship early, so the listener can calibrate how much weight to give the rest.
• It’s fully acceptable to decline to comment on something outside your knowledge — say so plainly rather than guessing.
• If you can’t give a genuinely positive reference, it’s more professional to say you’re not the best person to ask than to write something lukewarm that damages the candidate.

Practice Exercise

1. Write a two-sentence opener stating the scope of a working relationship with a former colleague.
2. Write one strength backed by a specific example, avoiding general adjectives.
3. Draft a tactful sentence naming a real area for growth, paired with evidence of improvement.
