Professional references can make a big difference when you’re applying for a job. A strong recommendation from someone who knows your work can help you stand out from other candidates. But there’s a right way – and a wrong way – to go about it.

That’s because your references aren’t just a list of names. They’re people who know you and can speak positively about your skills, work ethic, and character. They give employers a glimpse of what you’re like in action, so it’s important to know the dos and don’ts.

Do: Choose the right people

Not all references are created equal. You want individuals who can speak honestly and positively about your strengths and experience.

Before writing your list, ask yourself:

  • Does this person know my work well?
  • Can they give examples of my skills and character?
  • Will they give a positive recommendation?

Former supervisors and managers usually make the best references, but teachers, mentors, and even coworkers are great options—especially if they’ve worked closely with you. If you’re unsure, reach out to see if they feel comfortable serving as a reference.

Don’t: Put references directly on your resume

It might feel easier to list your references directly on your resume, but today it’s considered outdated. Your resume highlights your achievements, work history, and skillsets. You don’t want to lose valuable space by including your references’ contact information.

This also keeps your resume clean and focused, and it protects your references’ privacy. Most employers will ask for a reference list much later in the hiring process, so there’s no reason to include it upfront unless they specifically request it.

Do: Keep a list ready

Even if references don’t belong on your resume, it doesn’t mean you shouldn’t have a polished list ready before you start applying. You don’t want the stress of pulling together contacts last minute.

Your reference list should be its own document and include:

  • The reference’s full name
  • Their job title
  • Company or organization
  • Phone number and email
  • Your relationship (former manager, colleague, professor)

Some hiring managers might request references early in the process, while others wait until they’re close to making an offer, being ready well in advance is key.

Don’t: Surprise your references

Always give your references a heads-up when you’re applying for new roles. Not only is it polite, but most professionals want the chance to prepare and review notes on their experience working with you.

Before listing them as a reference, reach out and let them know:

  • The type of roles you’re applying to
  • What skills or experience the hiring manager might ask about
  • Any background or context they should know
  • How much you appreciate their help

This extra step helps them feel prepared and ensures they can give you the best possible recommendation.

Do: Keep your reference list up to date

Your references should include people who can speak to your most recent work experience. If someone on your list hasn’t supervised or worked with you in a while, consider replacing them with a contact more current.

A teacher from 20 years ago may be able to say you were a great student back in the day, but they won’t be able to speak to your current leadership or technical skills. Instead, think of a recent supervisor, mentor, or close coworker who can provide examples of your accomplishments.

This shows employers that you’re actively maintaining your professional relationships and staying engaged in your field.

Don’t: Forget to say thank you

While most people are happy to help, your references are still giving you their time. They’re writing letters, filling out forms, or fielding phone calls to support you in the next step of your career.

Be sure to show your appreciation with a thank-you note, message, or small gesture like a coffee. It’s the right thing to do, and it helps maintain a positive relationship for future reference needs.
