What Is a Background Check? An Employer Guide

Employers use background checks to help confirm that information provided by a candidate aligns with primary source records and with job requirements. A thorough background check can provide useful insights for mitigating risks for operations, brand, and workforces.

In this article, we explain what a background check is, what it typically includes, how employment screening works, and what employers should understand about compliance requirements and the candidate experience. Whether you are creating a new hiring program or refining an existing one, this overview is designed to help you build workforce trust throughout the entire employee lifecycle.

What is a background check?

A background check is a structured investigation into an individual’s past activities and credentials to confirm they are qualified for the role and mitigate risk. The specific components of a background check are selected by an employer and may depend on the position, industry, candidate and job location.

Background screening is not about eliminating candidates unnecessarily. It is about finding the best qualified candidate while applying consistent, job-related criteria to gain insights that may help mitigate risk, support compliance requirements, and facilitate decisions that can help protect the organization and its workforce.

Background checks can also help confirm qualifications for roles that involve safety, security, or regulatory oversight. Through screening, employers help protect their employees, customers, and organizational assets while potentially reducing their exposure to negligent-hiring claims.

For candidates and employees, a thorough background check is not an obstacle; it’s a selling point. In First Advantage’s 2026 Global Workforce Trends Report, seven in 10 candidates say that screening increases their trust in an organization. By creating and using a background check policy that sets standards across similar roles, employers create documented, defensible hiring practices that help support fairness and compliance. When handled responsibly, background checks for employment support both employer needs and a positive candidate experience.

Where do background checks fit into the hiring process?

An employment background check occurs after a candidate reaches a defined stage in the hiring workflow, often following a conditional job offer. State and local laws may dictate the timing of a background check, so employers should consult with their legal counsel on timing to ensure compliance with laws. Background checks are conducted only after specific disclosures and candidate consent are obtained.

Background screening packages are tailored to the role and may confirm employment history, verify education, search criminal records, or involve other job-related searches. Laws and regulations may require specific checks for regulated roles. A healthcare position, for example, may require professional license verification, while a transportation role may require more extensive safety-related checks to identify driving-related convictions and meet DOT compliance regulations. Employers who are unsure of their screening requirements should consult their legal advisors.

What do background checks include?

Employment background checks are modular, meaning employers select components based on the role, industry, and location. While there is no single universal package, most screening programs are built around a few core pillars, which include:

• Criminal history searches
• Employment, education, and credential verifications
• Reference checks

Some roles may also require additional screenings based on regulatory or safety requirements, including financial accountability checks, Motor Vehicle Record searches, sanctions searches, and social media searches. Identity verification is not usually included as a standard offering and may be added before the start of the screening process to help mitigate identity fraud risk, accelerate background checks by pre-populating required identity data, and potentially reduce errors caused by manual entry.

While background screening is sometimes treated as a one-and-done step in the hiring process, employers are increasingly moving towards an employment lifecycle model in which key checks, such as criminal history checks, credential checks, and social media searches, are renewed at scheduled intervals. Risk evolves over time, and ongoing monitoring helps employers build workforce trust past the point of hire.

Let’s review some of the core components of background screening, including:

Criminal history searches

Criminal history searches are a core component of background screening, helping organizations mitigate risk and build workforce trust. In the U.S., criminal record searches can be conducted at the federal, state, or county level. Most organizations conduct county court criminal record searches, which will search for a candidate’s felony and misdemeanor convictions and pending cases. County searches are based on the candidate’s address history. In most cases, records go back seven years. Statewide searches may be available in some locations where the state maintains a publicly available, centralized repository of criminal records. A federal court search may be added to look for crimes prosecuted in the federal district courts, such as kidnapping and international drug trafficking.

Criminal history checks are country-specific. In addition to searching for records in the country of residence, organizations hiring an international workforce should consider conducting additional searches based on candidate’s past countries of residence for a more thorough overview of their criminal history. The availability of records, legal and regulatory requirements, and information that may be disclosed can differ from one country or territory to another, based on local laws and regulations, with some countries restricting or banning employment background checks altogether. Likewise, costs and turnaround times can vary. Employers should consult with their legal advisor on country-specific laws about background screening and hiring.

Employment, education, and credential verifications

Employment verification confirms a candidate’s prior positions, job titles, and dates of employment. Education verification confirms degrees earned, institutions attended, and dates of completion. Credential checks may include professional licenses or certifications required for the role.

While always a source of useful information, these verifications are especially important in regulated industries, such as healthcare, financial services, and education, where qualifications are directly tied to compliance and safety requirements. Challenges can arise when the search requires manual outreach to the organization, when institutions or employers have closed and are no longer available, or when documentation is limited, which can affect turnaround times.

How do employment background checks work?

Employment background screening is a structured process that balances legal requirements, data accuracy, and candidate experience. While workflows vary, most checks follow a consistent sequence of steps, which include candidate consent through written authorization and disclosure, candidate data collection, record searches, and verification.

Consent, disclosure, and data collection

Before conducting a background check, employers must provide clear disclosure and obtain written authorization from the candidate. Disclosure documents must be presented separately from other hiring materials and explain that a background check will be conducted. Legal requirements for disclosure and authorization are technical and can vary based on location, so legal counsel is recommended.

Key data points, such as names and prior addresses, may be collected to facilitate the search and get timely results. Employers can improve the quality of background check reports by providing candidates with clear instructions that stress the importance of providing thorough information and verifying the data they’ve entered before submitting it.

Once consent is obtained and candidate personal information has been collected, information is gathered from a combination of databases, court records, and other verification sources when required.

Timelines and what affects turnaround times

Many employment background checks are completed within a few business days, but timelines vary based on type of checks performed, the source, and the jurisdictions involved. Some regulated roles may require fingerprint-based record checks, which have unique requirements and can take longer. Ninety percent of First Advantage’s U.S. criminal screens are completed within one day.¹

Factors that affect turnaround times include:

• Court access
• Employer or institution response time
• International searches
• Incomplete candidate information

While speed is important, thoroughness and compliance remain the priority. Reliable screening supports better decisions and can help to reduce downstream risk.

Compliance essentials for employers

Compliance is a critical part of any background screening program. Employers must balance business needs with legal obligations and candidate rights across federal, state, and local regulations.

A compliant approach helps with fairness, consistency, and transparency throughout the hiring process. It also protects employers from regulatory risk and supports a more positive candidate experience.

Compliance is not static. Regulations around background checks evolve constantly, and organizations and the roles for which they are hiring will continue to change. Companies should have their background screening policy regularly reviewed by qualified legal counsel to keep up with the changes in the law.

Choosing a screening provider

Background checks are typically completed through third-party screening providers who have the technology, resources, and expertise to get fast answers from sources, automate time-consuming processes, and provide candidates with a positive, frictionless experience.

Choosing the right background screening provider is a crucial decision that can impact every aspect of the employment process, from onboarding to post-hire monitoring. Factors employers should take into consideration when evaluating providers include:

• Range of solutions available, including identity and social media screening
• Turnaround times
• Available integration partnerships
• Compliance resources
• Industry-specific support

While some employers use multiple screening providers for checks, provider consolidation is trending across industries.² Organizations that rely on a single provider benefit from increased efficiencies, a centralized platform, and reduced screening costs due to volume discounts.
