Applying for a job can feel like a series of steps: the application, the interview, and then — often — a consent form asking permission to run a background check. While these checks are a routine part of hiring, many people are unsure about exactly what an employer can see, what stays off-limits, and how information about their health fits into the picture.
Background check services are the companies that gather and verify records on behalf of employers. Understanding how they work can help you prepare, correct errors early, and move through the hiring process with confidence instead of worry.

What Are Background Check Services?
A background check service is a company that compiles information about an individual and provides it to an employer, landlord, or volunteer organization that has requested it. These services do not make hiring decisions. They gather records from courts, government agencies, schools, former employers, and other verified sources, then deliver a report to the requesting organization.
Employers use these reports to confirm that the information a candidate has provided is accurate and to assess whether the person is a suitable fit for a particular role. The depth of a check usually depends on the position: an entry-level office job may involve only a few verifications, while roles involving money, safety, or vulnerable populations often involve a more thorough review.
What Employers Commonly Screen For
Not every employer runs the same check, and some industries have specific requirements. That said, the following categories appear most often.
Identity and Work Eligibility
Employers typically confirm a candidate’s legal name, date of birth, and address history, and verify that the person is authorized to work in the country where the job is located. This step also helps confirm that the applicant is who they say they are.
Criminal Records
This is the category most applicants wonder about. Searches generally cover felony and misdemeanor convictions at the county, state, and sometimes federal level, depending on the role and local rules. Many employers now consider how recent an offense is and whether it relates directly to the job. Arrests that did not lead to conviction, sealed records, and expunged records are frequently excluded or restricted by law or company policy.
Employment and Education Verification
Former employers are usually contacted to confirm job titles, dates of employment, and sometimes eligibility for rehire. Schools are contacted to confirm degrees, diplomas, and dates of attendance. Discrepancies in these areas are among the most common reasons an offer is delayed or withdrawn, and they are often the result of simple record-keeping errors rather than intentional misstatements.
Professional Licenses and Certifications
For roles that require a license, registration, or certification — such as those in healthcare, education, finance, or skilled trades — the issuing body is checked to confirm the credential is current and in good standing.
Credit and Financial History
Credit checks are not universal and are usually limited to positions involving significant financial responsibility or access to sensitive data. Where they are used, the report generally focuses on patterns relevant to the job rather than a numerical score.
Driving Records
If the role involves driving a company vehicle, transporting people, or operating equipment, employers may review a motor vehicle record for valid licensure and recent violations.
Drug Screening
Some employers include drug testing as part of pre-employment screening, particularly in safety-sensitive roles. This is a health-related process with its own rules, consent requirements, and confidentiality protections, and it is handled separately from the records-based portion of the check.
Reference Checks
Beyond automated records, many employers contact professional references directly to ask about work habits, reliability, and collaboration. These conversations are usually conversational rather than scored.
What Employers Usually Do Not See
It is just as important to know what a standard background check does not include. Most employment screening reports exclude:
- Medical records, diagnoses, and treatment histories — these are not part of a standard employment background check
- Genetic information, which is broadly protected from use in employment decisions
- Protected characteristics such as race, religion, national origin, sex, or disability status, which cannot legally factor into hiring
- Expunged, sealed, or juvenile records, where the law requires them to be withheld
- Personal social media passwords, which employers generally may not demand
Where Health Information Fits In
Because health is a sensitive subject, it helps to separate screening from medical evaluation. Standard background checks are record-based and do not pull your medical history.
Some employers do arrange a separate health-related step for roles with physical demands or safety responsibilities. This might include a fitness-for-duty evaluation, a physical examination, or a drug test conducted after a conditional offer. In most places, these evaluations are:
- Performed after a job offer is made, not before
- Limited to information relevant to the essential functions of the job
- Kept confidential and stored separately from the personnel file
- Shared only with those who need to know the outcome
Additionally, disability protections in many jurisdictions mean an employer generally cannot reject an applicant simply because of a health condition or disability, provided the person can perform the essential functions of the job with or without reasonable accommodation. If you have questions about how a specific health condition might interact with a job requirement, speaking with a qualified professional or legal advisor can help clarify your situation.
How the Screening Process Works
- Consent: The employer asks for written permission before the check begins. In most places, consent is required by law.
- Disclosure: A separate document explains that a report may be obtained and how it will be used.
- Gathering: The screening service collects records from the relevant sources, which can take anywhere from a few days to a few weeks.
- Reporting: Results are delivered to the employer, who reviews them against the requirements of the role.
- Review and dispute: If a report contains an error, you typically have the right to see it, dispute it, and request a correction.
Your Rights as an Applicant
- You should be asked for permission before a background check is run.
- You are generally entitled to know what will be checked and why.
- You can request a copy of the report that was used in a hiring decision.
- You can dispute inaccurate or incomplete information and ask for it to be corrected.
- If a report influences a decision not to hire, you should receive notice and an opportunity to respond.
Practical Ways to Prepare
- Review your own records first. Request a copy of any consumer report about you and check for errors.
- Verify employment dates and titles. Confirm details with former employers or keep old offer letters and pay stubs on hand.
- Confirm your education records. Ensure your school has your correct name, including any name changes.
- Be consistent. Use the same legal name and dates across applications, résumés, and forms.
- Dispute problems early. Corrections can take time, so start the process before it becomes urgent.
- Ask questions. It is reasonable to ask what a check will include and how long it typically takes.
The Bottom Line
Background check services exist to help employers confirm that the information they have received is accurate and that a candidate is a good fit for a specific role. The most common areas of review are identity, work eligibility, criminal history, employment and education verification, and credentials relevant to the job. Personal medical information is not part of a standard employment background check, and health-related evaluations, when they occur, follow separate rules with strong confidentiality protections.
Knowing what to expect takes much of the uncertainty out of the process. Review your records, correct errors early, and keep your documentation organized. And if a health concern comes up as you consider a new role, it is always reasonable to talk with a qualified healthcare professional about your options and any accommodations that might support your success.
