Letter of Recommendation for Master's Applications
Last updated: September 2026
A letter of recommendation (LOR) is a reference written by someone who has taught, supervised, or worked closely with you, submitted alongside your Statement of Purpose to vouch for your readiness for graduate study. Most master's programmes ask for two or three — but the exact number, and how strong each one reads, depends entirely on who you ask and what you give them to work with.
How many do you actually need?
There's no single answer — it ranges from two to three at most universities, and occasionally more for research-heavy or funded programmes. Some application portals list a minimum but recommend submitting the maximum if you can. Treat the specific programme's application checklist as the only reliable source here, not a general rule you've read elsewhere.
Who to ask: academic vs. professional recommenders
Most master's committees expect at least one academic recommender — a professor, thesis supervisor, or research advisor who can speak to your ability to handle graduate-level work. A professional recommender (a manager or senior colleague) can round out the set, particularly if you've been working for a few years since graduating, but check whether the programme explicitly requires academic referees before relying on work references alone. When in doubt, pick the person who knows your actual work best over the person with the more senior title — specificity beats prestige almost every time.
What to give your recommender
A recommender writing from memory alone tends to produce a generic letter — not because they don't rate you, but because they don't have the specific details in front of them. Before you ask, prepare:
- Your CV or resume — so they can reference your full academic and work background, not just what they personally saw.
- Your target programmes and why — the same reasoning you're using in your Statement of Purpose, so the two documents reinforce each other instead of telling different stories.
- A reminder of specifics — the project, dissertation, or module where they directly saw your work, and the outcome or grade if relevant. This is what turns a vague letter into a credible one.
- The deadline and submission method — most programmes have referees submit directly through an online portal, which can take a recommender by surprise if they're expecting to just email a PDF.
Timing: ask early
A common guideline is at least three to four weeks before your earliest deadline — longer if you're asking a professor who's likely writing several letters that same admissions season. Asking late puts your recommender in a position to either rush a generic letter or decline. If you're applying to several universities with different deadlines, tell your recommender the earliest one and let them plan around it, rather than sending separate last-minute requests for each.
What makes a letter strong instead of generic
Admissions committees read a high volume of these letters, and the ones that stand out are specific: a real anecdote, a comparison to other students the recommender has taught ("one of the strongest in a cohort of X"), or a concrete outcome tied to your work. A letter that could be copy-pasted for any student — heavy on adjectives like "hardworking" and "dedicated" but light on detail — reads as generic even when it's positive. This is the same weakness a Statement of Purpose is checked for, and it applies just as much to the letters written about you.
Frequently asked questions
How many letters of recommendation do master's programmes need?
Most ask for two or three, but this varies by university and even by department within the same university. Always check the specific programme's application checklist rather than assuming a number — some accept a minimum of two but recommend three, and submitting fewer than requested can flag an application as incomplete.
Should I ask a professor or a manager for my recommendation letter?
For most master's programmes, at least one academic recommender (someone who taught or supervised your coursework or research) is expected, since the committee is assessing your readiness for further academic study. A professional recommender can add a second, complementary letter — especially useful if you've been out of study for a few years — but check whether the programme requires academic referees specifically before substituting a work reference for all of them.
What should I give a recommender before they write my letter?
At minimum: your CV or resume, your Statement of Purpose draft (or at least the target programmes and why you want them), a reminder of specific coursework, projects, or interactions they can speak to, and the submission deadline. The more concrete detail you hand them, the less generic the letter tends to read.
How far in advance should I ask for a recommendation letter?
A common guideline is at least three to four weeks before the earliest deadline you need it for, and longer if your recommender is a busy professor writing multiple letters during the same admissions season. Asking late increases the chance of a rushed, generic letter — or a recommender saying no.
Does a letter from a more famous professor matter more than the content?
No — admissions committees read hundreds of letters and can tell a specific, detailed letter from a generic one regardless of the recommender's title. A specific letter from someone who actually supervised your work is generally stronger than a vague, templated letter from someone with more prestige but limited direct knowledge of you.
