Ask at least two weeks before anyone will call them. Ask in one email that does the referee's homework: the job title, a link to the posting, your current resume, the two things you'd like them to mention, and the date the employer will get in touch. A referee who can say yes in 30 seconds usually does.
Who to ask, and who not to
Ask people who saw your work up close and recently. For most jobs, start with a former manager, then a senior colleague or client, then a professor if you graduated in the last few years.
UMBC's career center says good references can give first-hand examples of your work and character. Its examples include supervisors, professors, advisors and coaches. It rules out family and friends unless they knew you through work.
Leave two more people off: anyone you haven't spoken to in five years, and your current manager, unless they already know you're leaving. UK guidance from Acas tells employers it is best to ask for references at the job offer stage, because an earlier request can tip off your current employer.
Keep a list of three to five people so you can match the referee to the job.
How much notice to give
Give two weeks at minimum for a phone call or form, and a month for a written letter. Tufts gives its students that same split: two weeks for a reference, a month for a letter. UMBC also names two weeks as the usual minimum.
A referee needs time to reread your resume and recall your work. With two days' notice, they wing it, and it shows.
In practice, ask when you reach the interview stage, not when the employer asks for names. Then send a one-line heads-up the day you hand over their details, so the call is not a surprise.
What to put in the email
| Include | Why the referee needs it |
|---|---|
| The exact job title and company | So they can pitch their comments at the right level |
| A link to the posting (or the PDF) | So they can echo the words the employer cares about |
| Your current resume, attached | Their picture of you may be years out of date |
| Two specific points you'd like them to mention | Referees want a steer; give them one |
| Who will contact them, how, and when | Phone, email or form, and the likely week |
| The deadline | So a slow yes doesn't become a no |
| An easy way to decline | Costs you nothing and gets you honest answers |
UMBC suggests handing referees a short list of strengths tied to the job you want. Keep it to two points. With more than that, the key ones get lost.
Template 1: former manager
Subject: Reference request, Operations Analyst at Northwind Logistics
Hi Dana,
I hope things are going well at Harlow. I've reached the final stage for an Operations Analyst role at Northwind Logistics and they've asked for three referees. Would you be willing to be one of them?
The posting is here: [link]. The role is close to what I did on your team, so if you're comfortable, it would help most if you could speak to two things: the dispatch dashboard I built in 2024 (the one that cut daily planning time from about 90 minutes to 25), and how I handled the Q3 backlog with the two temp hires.
I've attached my current resume so you have the recent detail. Northwind's recruiter, Priya Shah, will call or email you during the week of October 20. If that timing is hard or you'd rather not, just say so, no explanation needed.
Thanks either way, Dana. I learned a lot on your team.

Template 2: professor
Subject: Reference request, graduate data analyst at Meridian Health
Dear Professor Okafor,
I was in your Applied Statistics (STAT 3410) course in spring 2025 and completed the capstone on hospital readmission rates with you as my advisor. I'm applying for a graduate data analyst position at Meridian Health and they've asked for an academic referee. Would you be willing to act as one?
The posting is here: [link]. If it's useful, the two things most relevant to the role are the capstone (the logistic regression model that reached 0.81 AUC on the public dataset) and the R package I documented for the class.
I've attached my resume and a one-paragraph reminder of the capstone. Meridian will send a short online form rather than call, and they've asked for it back by November 3.
I know this is a busy point in the semester, so please tell me if the timing doesn't work.
Thank you, Amara Diallo amara.diallo@email.com
Template 3: colleague
Subject: Would you be a reference for me?
Hi Tom,
Quick one. I'm in the final round for a Senior Account Manager role at Brightwave and they want a peer reference as well as a manager. You and I worked the Calloway account together for two years, so you're the obvious person. Would you be up for it?
Posting here: [link]. If they ask, the two things I'd love you to mention are the renewal we saved in 2025 (the one that went from a cancellation notice to a three-year deal) and how we split the onboarding work when the team was short.
Resume attached. Their HR team, not the hiring manager, does the calls, probably the week of October 27.
If you'd rather not, or it's awkward with your current role, no problem at all.
Cheers, Sam
We counted our three templates: 157, 148 and 130 words, subject lines left out. If yours runs past 200, you're explaining the job instead of linking to it.
Drafting the request with our email writer
Here is how our email writer is set up, taken from the instructions it runs on:
- One box, "What is the email about?", holds your facts. Recipient and your name are optional.
- There are three lengths. Short aims for 60 to 90 words, Medium (the default) for 100 to 150, and Long for 180 to 250. Our templates run 130 to 157, so Medium is the closest fit.
- It returns a subject line first, then the body. It is told to skip stock openers such as "I hope this email finds you well."
- It writes text only. You still attach the resume and paste the posting link yourself.
Fill the box with facts, not with "write a reference email." For Template 1, it would read: "Ask Dana, my former manager at Harlow, to be a reference for the Operations Analyst role at Northwind Logistics. Points: the dispatch dashboard that cut planning from about 90 to 25 minutes, and the Q3 backlog with two temp hires. Recruiter Priya Shah will contact her the week of October 20. Make it easy to say no." Leave a detail out and the draft gets vaguer, so check every name, number and date before you send.
Follow up once, not three times
If you've heard nothing after five working days, send one short reply on the same thread: "Hi Dana, just checking this reached you. No rush if you need more time, but Northwind will reach out the week of the 20th, so I wanted to confirm you're happy to be listed." Then stop.
A second nudge reads as pressure. Treat silence after the follow-up as a no, and move to the next name.
Once they say yes, two more emails matter: the heads-up on the day you give their details to the employer, and a thank-you after the process ends, whatever the result. UMBC tells students to thank references whether or not the job came through.
When someone says no
Say thank you and mean it. A no now beats a lukewarm reference later, and refusals are often about time or company policy, not about you.
Then replace them, and don't list them anyway. Tufts tells students to always ask before listing someone, and a referee who gets a surprise call is the worst outcome.
Not sure which two points to request? Run each story through the STAR mode of the interview answer generator. It returns four to six short cue lines, and the best two can go straight into your email.
References in the UK
UK employers usually don't have to give a reference unless they signed an agreement to or work in a regulated field such as financial services. If they do give one, it has to be fair and accurate, and it may list little more than your job title, salary and dates. So a warm reference from a UK former manager may come from them as a person, not through their employer.
Wherever you apply, ask each referee whether they'd rather take a call or fill in a form, and tell the employer.
FAQ
How much notice should I give a referee?
At least two weeks for a phone call or a short form, and about a month if they need to write a letter. Career centers at Tufts and UMBC both give two weeks as the minimum. Ask when you reach the interview stage, and send a reminder on the day you hand over their details.
How do I ask a professor for a reference?
Remind them who you are in the first sentence: the course, the semester, and the project or paper you did with them. Attach your resume and a one-paragraph summary of that project, link the posting, and say whether the employer will call or send a form. Give a month if they need to write anything.
