Quick definition
A reference check is a verification process where an employer contacts a candidate's former managers, colleagues, or other professional contacts to confirm their employment history, performance, skills, and work behavior. Reference checks are typically conducted after a job offer is extended or as a final step before hiring. According to a 2026 SHRM report, 87% of employers conduct reference checks, and candidates who provide strong, specific references are 40% more likely to receive a final offer.
Direct answer
A reference check is a verification process where an employer contacts a candidate's provided references — typically former managers, colleagues, or other professional contacts — to confirm employment history, assess performance, evaluate skills, and gather insights about the candidate's work behavior. Reference checks are usually conducted after a conditional job offer is extended or as a final step before hiring. According to a 2026 SHRM report, 87% of employers conduct reference checks, typically contacting 2-3 references per candidate.
During a reference check, the employer (or a third-party service) asks references about the candidate's strengths, areas for improvement, specific accomplishments, reliability, teamwork, and whether they would rehire the candidate. The questions are often structured to verify claims made during the interview and to uncover any concerns not revealed during the hiring process. A 2026 LinkedIn study found that 12% of reference checks reveal information that changes the hiring decision, usually related to interpersonal issues or performance discrepancies. Candidates who provide strong, specific references who can speak to quantified achievements are 40% more likely to receive a final offer.
Candidates should prepare their references carefully. Choose references who can speak specifically about your work — ideally former direct managers, not just colleagues or friends. Brief your references on the role you are applying for, the key accomplishments you want them to highlight, and the timeline (so they are expecting the call). According to a 2026 Glassdoor study, 68% of hiring managers consider reference quality when making the final decision, and references who provide vague or generic feedback can hurt your chances. Always ask permission before listing someone as a reference and thank them afterward.
How it works
Reference selection
The candidate provides 2-3 professional references, typically former direct managers, with contact information and their relationship to the candidate. The candidate should brief each reference beforehand.
Contact and interview
The employer (or background check company) contacts each reference, typically by phone, asking structured questions about the candidate's performance, strengths, areas for improvement, and rehire eligibility.
Verification
The employer verifies the candidate's employment dates, titles, responsibilities, and key accomplishments as stated during the interview process.
Decision input
Reference feedback is compiled and considered alongside interview scores. 12% of reference checks reveal information that changes the hiring decision (LinkedIn, 2026). The final offer may be confirmed, modified, or withdrawn.

Frequently asked questions
What is a reference check?
A reference check is a process where an employer contacts a candidate's former managers or colleagues to verify employment history, performance, and work behavior. According to a 2026 SHRM report, 87% of employers conduct reference checks, typically contacting 2-3 references per candidate.
Who should I use as a reference?
Choose former direct managers who can speak specifically about your performance and accomplishments. Avoid colleagues, friends, or family members. A 2026 Glassdoor study found that 68% of hiring managers consider reference quality in their decision, so choose references who can provide specific, positive, quantified feedback.
What questions do employers ask references?
Common questions include: 'What were their key strengths?,' 'What areas could they improve?,' 'What were their main accomplishments?,' 'How did they work with the team?,' and 'Would you rehire them?' The goal is to verify interview claims and uncover any concerns.
Should I brief my references before they are contacted?
Yes. Tell each reference about the role you are applying for, the key accomplishments you want them to highlight, and when to expect the call. This ensures they are prepared and can provide relevant, specific feedback rather than being caught off guard.
Can a reference check change the hiring decision?
Yes. A 2026 LinkedIn study found that 12% of reference checks reveal information that changes the hiring decision, usually related to performance discrepancies or interpersonal issues. This is why providing honest, strong references who can speak to your actual work is important.
Do I need to ask permission before listing someone as a reference?
Yes, always. Ask permission before listing anyone as a reference, brief them on the role, and confirm their contact information. Failing to ask permission can result in unprepared references who provide vague or negative feedback. Thank them afterward, regardless of the outcome.
