Building a Professional References List: Selection, Permission, and Preparation

A useful reference can describe work they actually observed. That may be a former supervisor who reviewed your decisions, a client who received your deliverables, or an instructor who assessed a substantial project. A prominent name with little knowledge of your work may have less useful information.

Prepare the list before an employer requests it. Choose people who observed relevant work, obtain their agreement and preferred contact details, and give each person the vacancy and resume they may be asked about.

Understand what the employer is trying to verify

The Office of Personnel Management’s reference-checking guidance describes checking application information and examining past performance against the competencies needed for a job. Potential sources include supervisors, peers, and people the applicant supervised.

OPM describes reference checks as usually occurring near the end of selection, after the field has narrowed. Ask the recruiter when contacts are expected so your references can plan for the request.

Separate a performance reference from basic employment verification. A person who can discuss how you handled a project serves a different purpose from an office that confirms job title and dates. Ask which information the hiring team needs so you do not provide the wrong contact for the task.

Choose people who know the relevant work

Start with the position’s responsibilities. For an account-management role, someone who observed your handling of customer commitments may be useful. For a laboratory role, a supervisor who saw your documentation and procedural work may have better evidence than a contact who knows only your general reputation.

CareerOneStop’s reference guidance recognizes employment, professional, academic, and personal references. Its employment category includes clients and people for whom you performed volunteer or other work. Academic references can be appropriate for students and recent graduates.

Use a private selection matrix to compare the evidence each person can discuss. These sample entries show the format:

Potential reference	What they directly observed	Limitation to remember
Former team manager	Weekly reporting and deadline decisions in 2022–2024	Has not seen the applicant’s later role
Volunteer coordinator	Event logistics and communication in 2025	Cannot verify paid employment details
Project instructor	Research method and written analysis	Did not supervise workplace performance

Choose references to match the employer’s request and state each relationship accurately. Identify a peer, client, supervisor, or instructor so the recruiter can interpret the work they observed.

Ask a specific question and allow a real choice

CareerOneStop recommends asking before sharing a person’s name and confirming their preferred contact method and availability. It also suggests explaining the search and sharing the resume and job description.

An original request template:

“I’m applying for an operations coordinator position involving scheduling and weekly reporting. Would you be comfortable serving as a reference about the work we did together on the service team? I can send the posting and my current resume. Please let me know which contact details I may share and whether you have any availability limits.”

If the person declines or says they cannot discuss performance, thank them and choose another suitable contact. Do not press them to promise a particular rating. An honest reference may describe both strengths and areas where you developed.

For someone you have not contacted recently, briefly reintroduce the shared work before making the request. A date range and project name can help them place the relationship without a long career history.

Prepare a separate reference sheet

The University of San Francisco career center recommends supplying 3–5 references when requested unless the employer specifies otherwise. It advises keeping the list separate from the resume and including the reference’s name, current title, organization, email, and telephone number.

Follow the requested number and relationship types. If the employer asks for two former supervisors, select those contacts first and discuss an alternative if one is unavailable.

Use this original field layout for each person:

Name and current title: confirmed directly with the reference.
Current organization: distinguish this from the organization where you worked together.
Relationship: for example, former direct supervisor.
Shared work period: the dates during which they observed you.
Approved contact details: the email and phone they authorized you to provide.
Relevant context: a short factual description of the work they can discuss.

Put your own name and the position at the top of the document. Avoid putting reference contact information on a public portfolio or publicly downloadable resume. A private reference sheet gives you more control over where the information goes.

Send a brief factual preparation note

Send the role, submitted resume, shared work dates, and a few projects the person observed. Here is a sample preparation note:

“The role focuses on coordinating requests across teams. We worked together from June 2022 through August 2024. Projects you directly supervised included the weekly backlog report and the handoff checklist. I have attached the resume submitted for this application. The recruiter said they may contact you next week.”

For a result on the resume, provide the reference with its scope, period, and measurement. A task-level improvement should identify the task and the work they observed. Invite corrections if their records differ.

Allow them to describe the work in their own words. If they correct your memory about a date or responsibility, resolve the discrepancy in your own records before the check rather than asking them to repeat the incorrect version.

Handle a current-manager request explicitly

If your current employer does not know about the search, tell the recruiter before providing a current manager’s contact information. Ask whether a former manager or another relevant reference can be used at that stage.

An original response:

“My current employer is not aware that I am exploring opportunities. I can provide two former supervisors now. Could we discuss the timing and need for a current-manager reference before anyone contacts them?”

Ask the recruiter to confirm the timing and any acceptable alternative in writing. Use that response to decide when to provide a current manager’s details and whether the process fits your confidentiality needs.

For a former manager with whom you had a difficult relationship, explain the situation briefly and factually if necessary. Offer another person who directly observed the work, while accurately identifying their role. Avoid speculative accusations about what a former colleague might say.

Keep a small contact log

A reference may be helping with several applications. A private log can reduce missed messages and repetitive requests.

Record the employer, role, agreement date, approved details, anticipated contact period, and availability. A useful entry is: Employer: ___; role: ___; permission confirmed: ___; expected contact dates: ___; unavailable times: ___; outcome: ___.

When a process stalls, do not repeatedly ask the reference whether they have heard anything. Use the recruiter’s stated timeline for follow-up. If a reference becomes unavailable, notify the recruiter and provide a replacement only after that person agrees.

Close the loop after the decision

Thank people who took the time to help, regardless of the outcome. Tell them when the search ends so they know whether further contact is likely. If you accept a role, a short update about the work you will do is enough; there is no need to share private compensation terms.

Before the next search, confirm current titles, contact preferences, availability, and which projects each person can discuss. Update the sheet for the new employer’s requested relationships and roles.
