11 Reasons To Conduct Background Investigations

Thorough background investigations protect the integrity of any organization. They uncover red flags pertaining to violence, fraud, or misconduct, and they create the foundation for confident, informed hiring decisions. This guide covers eleven reasons why background investigations matter and how to conduct them effectively.

Why conduct a background investigation?

Conducting a background investigation is not just about identifying potential problems. It is about building a secure, transparent working environment where employees, customers, and partners can trust the people they work alongside. Here are eleven specific reasons why a background investigation is a standard part of a responsible hiring process.

Risk mitigation

Background investigations are a proactive measure to mitigate risks related to hiring individuals with a history of misconduct or fraud. They help prevent potential liabilities from negligent hiring decisions that could damage the organization's reputation and expose it to legal action.

Enhanced workplace safety

Thorough checks ensure that individuals with a history of violent or harmful behavior are identified before they join the team. This instills a sense of security among existing employees, which directly supports morale and productivity. Organizations with hostile work environment concerns often trace issues back to hiring decisions made without adequate background checks.

Informed decision-making

Background investigations equip employers with crucial information, allowing them to make evidence-based hiring decisions. This in-depth knowledge is pivotal in selecting candidates who align with the organization's values and the specific requirements of the role.

Verification of credentials

Resume fraud remains a real and documented problem. A background investigation authenticates the information provided by applicants, ensuring that candidates possess the qualifications they claim. Misrepresented credentials, particularly in roles requiring specific expertise, can lead to underperformance, internal conflict, and reputational damage.

Regulatory compliance

Many industries are bound by laws and regulations mandating background checks. Thorough investigations ensure compliance with legal standards, averting potential fines and legal repercussions. Organizations that skip required checks in regulated sectors face penalties that can far exceed the cost of the check itself.

Protection of vulnerable populations

In organizations where employees interact with children, elderly individuals, or people with disabilities, background investigations are particularly important. The due diligence required to protect these populations is both a legal obligation and a clear ethical standard.

Customer trust and brand image

Due diligence in hiring reflects an organization's commitment to integrity and reliability. A well-documented background investigation process signals that the organization takes its responsibilities seriously.

Reduction in turnover

By confirming the suitability of candidates before hiring, organizations reduce the likelihood of early departures driven by misalignment between candidates and roles. The cost of a failed hire, in recruiting, onboarding, and lost productivity, substantially exceeds the cost of a thorough background check.

Ensuring skill competency

A background investigation goes beyond character assessment. It validates the proficiency and competency of a candidate in their respective field, ensuring that the organization is hiring someone who can actually perform the role at the level claimed in their application.

Transparency and disclosure

Background investigations promote an atmosphere of openness and disclosure, enabling candid conversations between employers and potential employees. Candidates who know a background investigation is standard are also signaled that the organization operates with accountability as a norm.

Insurance and liability reduction

Many insurance providers offer reduced premiums to organizations that conduct regular background checks, recognizing the decreased likelihood of workplace incidents and related claims. The financial benefit compounds over time and can meaningfully offset the cost of the process itself.

How to conduct background investigations

A well-executed background investigation is a significant responsibility and must be approached with care, fairness, and deep respect for privacy. Work through these steps in sequence to build an investigation process that is consistent, legally sound, and fair to candidates.

1. Obtain consent. Before starting, secure written consent from the candidate. This is legally required in most jurisdictions and essential when using a third-party service.
2. Gather basic information. Collect the candidate's full name, date of birth, Social Security number or equivalent, previous addresses, and past employers.
3. Criminal record check. Investigate local, state, and federal databases for any criminal history. Consult employment counsel on how applicable law limits your use of this information in hiring decisions.
4. Verify educational and professional credentials. Contact issuing institutions directly to confirm degrees, certificates, and professional licenses. Resume fraud in this area is well-documented and points to integrity concerns that matter beyond the specific credential.
5. Past employment verification. Contact previous employers to confirm positions held, duration of employment, responsibilities, and reasons for leaving. Understanding why a candidate left previous positions helps predict fit within your team and culture.
6. Credit history check. For roles with financial responsibilities, consider a credit check as an additional data point. Adhere to applicable laws, as some jurisdictions restrict use of credit history in hiring decisions.
7. Reference checks. Reference checks offer a direct line to people who have worked with the candidate. Seek specific examples of the candidate's performance, working style, and conduct rather than general assessments. Balance what references share with the broader picture from other verification steps.
8. Drug screening. Depending on the role and company policy, drug screening may be required. Ensure your process is consistent and compliant with local law.
9. Online and social media review. Publicly available information on professional platforms can provide additional context. Apply the same review standard to all candidates and document your process. See the guide on implementing a social media use policy for how to set organizational norms around this area.
10. Additional role-specific checks. Candidates driving company vehicles may require a driving record check. Those working with vulnerable populations may need more detailed criminal checks. Tailor the investigation to the actual risk profile of the role.
11. Review, decision, and documentation. Collate all gathered information and evaluate it against job requirements and company values. If adverse information may affect the hiring decision, the candidate must be informed and given the opportunity to contest or explain the findings. Document every step, finding, and decision, and stay current on background investigation laws, which vary by region and change over time.

The case for and against reference checks

Reference checks remain one of the most debated elements of background investigations. Here is a clear breakdown of where they add value and where their limitations require additional verification steps.

Why reference checks are worth doing

• They validate specific claims a candidate made about their performance, responsibilities, and achievements.
• They offer behavioral insights into work ethic, team dynamics, and interpersonal conduct that resumes and interviews cannot fully capture.
• Past behavior is often the best predictor of future behavior, and reference conversations can reveal conduct patterns relevant to your role.
• They can surface potential cultural fit issues or red flags before an offer is extended.

Where reference checks fall short

• Candidates select their own references, which introduces a positive selection bias. References are rarely people who will speak critically.
• Many employers restrict what employees can share beyond confirming employment dates and titles, limiting the depth of what you learn.
• Reference checks are time-intensive, particularly when coordinating multiple contacts across different time zones or organizations.
• Information from references may be outdated, especially for candidates several years past the referenced role.

Use reference checks as one element of the broader investigation, not as the primary verification mechanism. Combine them with employment verification, credential confirmation, and any role-specific checks your organization requires.

Where background investigations stand in 2025 and 2026

The legal and operational landscape for background investigations has shifted in several ways since this post was originally published. HR teams need to account for these developments in their current processes.

Ban-the-box laws have expanded significantly

As of 2025, more than 37 states and 150 cities and counties have enacted ban-the-box laws, which restrict when employers can ask about criminal history in the hiring process. The specifics vary by jurisdiction, including when the inquiry can occur, how the information can be used, and what individualized assessment steps are required before adverse action can be taken. According to EEOC guidance on background checks and criminal history, employers must ensure their screening criteria are job-related and consistent with business necessity to avoid disparate impact liability. Organizations with multi-state hiring should confirm their process complies with requirements in each jurisdiction where they operate and consult employment counsel, as enforcement activity in this area has increased.

FCRA compliance remains a high-stakes requirement

The Fair Credit Reporting Act governs how third-party background check results are used in employment decisions. In 2024 and 2025, the FTC continued to bring enforcement actions against employers who failed to provide required pre-adverse and adverse action notices, and courts have seen increased class action litigation in this area. The procedural requirements, notice, disclosure, and reasonable time for the candidate to respond, are non-negotiable and must be built into your investigation workflow.
