A kinder way to say “I can't write a recommendation letter”
Why it can fall flat
“I can't write a recommendation letter”
The word “can't” sounds like a closed door, and the person may hear that you think badly of them. Usually the real limit is time, how well you know them, or a personal policy, not doubt.
Say this instead
- 01
I'm not the right person to write this one, as we've only worked together on a single project. It says nothing about your work. Who else has seen more of it?

Choose this when the limited-contact reason is true, since it tells a report the no is about your view, not their ability.

Your request means a lot to me. I don't write recommendation letters for anyone on my team, so this isn't about you or your work. I'm happy to talk through who might suit the application.

Use it only if the rule is genuinely true, because applying it to everyone shows the no is not personal.
- 03
Honestly, I don't know your work well enough to write something useful, and a thin letter won't help you. Someone from your last project would do far better.

This suits a peer you like but haven't worked closely with, since it frames the no as protecting their application.

Hi Kendall, I'm going to pass on writing the letter. I'm swamped until the end of the month and couldn't do it properly. Hope the application goes well.

A quick, friendly refusal fits a peer when a real time crunch is the reason.

Quick heads-up: I'm going to step back from writing Gauri's letter. I've only managed her for three weeks, so I couldn't be specific. Mina led her last project and could say more.

Giving a factual reason and naming a better source lets you decline a request passed down from above.

Hello Dana, I'm declining to give a written recommendation for Tom, as I haven't worked with him recently enough to speak to his current skills. I hope the search goes well.

Short and factual, this fits an outside party asking, and it never criticizes the candidate.

It's kind of you to ask. Writing recommendation letters for clients isn't something I'm able to do, so I have to decline. I've enjoyed working with you and wish you every success with the application.

Hi Anika, Congratulations on the shortlist. I'm not able to write the letter for your course application, because I only managed your work on one project and couldn't give the detail a good letter needs. That says nothing about the quality of your work, which was solid. Your project lead from the spring could speak to it much better. Best wishes, Jordan
I'm not able to write one that would do you justice right now, and I'd rather say so plainly than give you a rushed one.
What to avoid
- Saying “maybe later” or “let me think about it” when the answer is no leaves the person waiting.
- Blaming a policy or rule only works if it is real and you apply it to everyone.
- Piling on excuses muddies things, while one true reason is clearer and kinder.
- Leaving the request unanswered is the worst option, especially when a deadline is close.
- Comparing the person with others or hinting at weaknesses in their work will hurt more than the refusal itself.
