When you've been working for a few years, your strongest referee is often a manager, not a professor. That's fine. Many programmes accept, and sometimes prefer, professional references for experienced applicants. The trick is making it easy for a busy manager to write a specific, credible letter.
Check the rules first
- Does the programme accept professional referees?
- Does it require at least one academic referee?
- Does the referee upload directly or send a letter to you?
- Is there a form with rating scales as well as a letter?
Who to ask
The best referee is someone who:
- Has directly supervised your work
- Can give specific examples
- Is reliable with deadlines
A senior title helps less than a detailed letter. A CTO who barely knows you writes a weaker letter than a team lead who saw your work every day.
The ask
Ask in person or on a call first, then follow up in writing:
Hi [Name], I'm applying for master's programmes in [field], starting [year]. Would you be comfortable writing a recommendation that speaks to my work on [project]? The first deadline is [date]. I'll send a short brief to make it easy.
Give them an easy way to say no. A reluctant referee writes a weak letter.
The briefing document
Send one page with:
- The programmes and deadlines, with submission links
- Why you're applying, in two or three sentences
- Three or four specific examples they witnessed, with outcomes
- Qualities the programme values (e.g. leadership, analytical skills, teamwork)
- Your CV
Example of a useful bullet:
"Led the migration of our field data app to offline-first sync in 2025, reducing failed submissions from rural users. You saw the planning and the rollout."
You're reminding them of facts, not writing their opinion.
What makes a professional letter strong
- Specific examples with results
- Comparison: "one of the strongest engineers I've managed in X years"
- Evidence of growth and learning ability
- Connection to the programme, i.e. why you're ready for graduate study
Mistakes to avoid
- Asking too late.
- Drafting the letter for them. It can backfire.
- No follow-up. Send a gentle reminder a week before the deadline.
- Not thanking them. Tell them the outcome either way.
