Ask someone who has supervised or taught you directly and can describe your work in detail. Ask early, weeks before the deadline, and ask whether they know your work well enough to write a strong letter, so they can decline if they do not.
Then make the job easy. Send the deadline and submission instructions, your resume, the job or program description, and a short list of the projects and results you hope they will mention.
Key takeaways
- A detailed letter from someone who knows your work beats a vague one from a famous name.
- Give as much notice as you can. UC Berkeley’s career office suggests at least two months for graduate school letters.
- Ask for a strong letter, not just a letter. That gives the writer a graceful way out.
- Send one organized packet: deadlines, instructions, your resume and reminders of specific work.
- In the United States, a student can waive the right to see a recommendation in their education records. The waiver must be voluntary and in writing.
01
Letter of recommendation or reference: which do you need?
They are different requests, and the posting or application will tell you which one applies.
| Question | Reference | Letter of recommendation |
|---|---|---|
| What it is | A name and contact details | A written, signed document |
| How it is used | The employer calls or emails the person | You or the writer submit it with the application |
| When it is needed | Usually late, when a few candidates remain | Usually up front, with the application |
| Where it is common | Most job applications | Graduate school, fellowships, academic jobs, and some roles in education, healthcare and government |
If an employer asks only for names, you do not need a letter. Our guide to job references covers that request.
02
Who should you ask for a letter of recommendation?
Pick the person who can give the most specific account of your work, not the one with the grandest title. UC Berkeley’s advice to its graduate students is blunt: a boilerplate letter from a renowned expert who shows only a passing acquaintance with you is unlikely to do you much good, and the most effective letters come from writers who are closely familiar with your work and can explain the basis for their endorsement.
| You are applying for | Strong choices |
|---|---|
| A job | A current or former manager, a senior colleague who led your projects, a client |
| Graduate school | Professors who taught or supervised you, or a supervisor from a job or internship related to the program |
| A scholarship or fellowship | A professor or mentor who can speak to the qualities the award names |
Berkeley also notes that letters from family friends and political figures are discouraged and may even be detrimental.
The end of an internship or a project is the best moment to ask, while the details are fresh. It is also one of the habits that helps turn an internship into a full-time offer.
03
When should you ask?
As early as you can. For graduate school letters, Berkeley’s career office recommends approaching writers at least two months before you need the letters, and points out that faculty are especially busy in November and December. For a job with a short deadline you will not have that long, so ask the day you decide to apply.
Once they agree, send your materials the same day, send a short reminder a week before the deadline, and thank them when the letter is in. When you hear the result, tell them, whatever it is.
04
How do you ask for a letter of recommendation?
Ask in a conversation when possible, and follow up in writing so the details are on record. Do not ask “Will you write me a letter?” Berkeley suggests asking whether the person feels they know you and your work well enough to write a strong one. Anyone who cannot will say so, and you will have avoided a lukewarm letter.
Subject: Request for a letter of recommendation, due [date] Dear [Name], I'm applying for [the job title at Company / the program at University], and I'm writing to ask whether you would be willing to write a letter of recommendation for me. I'm asking you because [you supervised my work on X / I took two courses with you and wrote my thesis under your guidance]. Do you feel you know my work well enough to write a strong letter? If not, or if the timing is difficult, I completely understand. The letter is due on [date] and is submitted [by upload link / by email to address]. If you agree, I'll send my resume, the description and a short summary of the work we did together. Thank you for considering it, [Your name] [Phone]
Subject: Reminder: recommendation for [Your name], due [date] Dear [Name], A quick reminder that the letter for [job or program] is due on [date]. The submission link is [link]. Please tell me if you need anything else from me. Thank you again, [Your name]
05
What should you give the person writing your letter?
A busy writer with nothing to work from produces a generic letter. Berkeley tells students to give each writer a portfolio of materials and not to make writers rely on memory for the details. For a job or a program, the packet looks like this:
- A cover note with the deadline, how and where to submit, and what the reader cares about.
- Your resume.
- The job posting or program description.
- Your cover letter or statement, even as a draft.
- Reminders of your work together: projects, dates, results, grades and any praise they gave you at the time.
- Any form they must fill in, with your details already completed.
Your list of resume accomplishments is a good source for the reminders.
Hi [Name], Thank you for agreeing to write this letter. Everything you need is here. Due: [date] Submit: [upload link or email address], addressed to [name or "Admissions Committee"] Applying for: [job title at Company / program at University] What they are looking for: [two or three qualities from the posting] Work you saw that fits: 1. [Project, when, and the result] 2. [Skill, with an example they witnessed] 3. [Anything they said about your work at the time] Attached: resume, description, draft cover letter or statement. [Your name]
Some writers will ask you to draft the letter yourself. Offer the cover note first. If they still want a draft, write it plainly as raw material for them to rewrite. The letter is their statement, and they sign it.
06
What does a strong letter of recommendation include?
You do not write the letter, but knowing its shape tells you what to give your writer.
[Date] [Recipient name or "Dear Hiring Committee,"] Opening: who the writer is, how they know the candidate, in what role and for how long, and a clear statement that they recommend the candidate for [specific job or program]. Evidence, first example: a specific project or responsibility, what the candidate did, and the result. Evidence, second example: a different strength that the role requires, again with a concrete instance. Working style: how the candidate works with others, handles feedback or solves problems, shown by something the writer observed. Closing: a direct recommendation, with a comparison to peers if the writer can honestly make one, and an offer to answer questions. [Signature, title, organization, phone, email]
One page is right for most jobs. Academic letters run longer: Berkeley notes that one to two pages is now the norm for faculty letters.
A good letter also leaves things out. Berkeley’s guidance says letters should not refer to personal information, such as age or marital status, that has nothing to do with your ability to do the job.
07
Should you waive your right to see the letter?
This question comes up on school and scholarship applications in the United States. Under FERPA, the federal student privacy law, college students have a right to inspect their education records. The regulations let a student waive that right for confidential letters of recommendation related to admission to an educational institution, an application for employment, or receipt of an honor.
The rules protect you in three ways:
- The institution cannot require the waiver as a condition of admission or of receiving a service or benefit.
- The waiver must be in writing and signed by the student.
- You can ask for the names of the people who provided letters, and you can revoke the waiver in writing for anything that happens afterward.
Whether to waive is your choice. Berkeley’s career office says that graduate programs generally prefer confidential letters and that most people waive.
A letter that a manager hands to you for a job application is different. You have already read it, and no waiver is involved.
FAQ
Frequently asked questions
How do you ask for a letter of recommendation?
Ask in person or by phone if you can, then confirm by email. Say what you are applying for, why you are asking that person and when the letter is due. Ask whether they know your work well enough to write a strong letter, and offer to send your resume and a summary of your work together.
How far in advance should you ask for a letter of recommendation?
As far as you can. UC Berkeley’s career office recommends at least two months for graduate school letters. For a job, ask on the day you decide to apply.
Who should write a letter of recommendation for a job?
Someone who supervised your work or worked closely with you and can give examples: a current or former manager, a senior colleague who led your projects or a client. A detailed letter from a direct supervisor is worth more than a general one from a senior executive who barely knows you.
Should I waive my right to see my letter of recommendation?
It is your decision. In the United States, FERPA lets students waive their right to inspect confidential recommendation letters, and an institution cannot require it. UC Berkeley’s career office says graduate programs generally prefer confidential letters and that most applicants waive.
