Hiring the right person is a major step toward building a strong team. In the year 2026, the process goes far beyond checking a few references or looking at a resume. With the rise of advanced technology and new legal rules, a standard review is no longer enough to protect your company. You need a clear plan to verify information while staying within the law. This guide will walk you through the modern steps to vet applicants safely and effectively, ensuring you find the best fit for your open roles.

Key Takeaways on Conducting Background Checks

  1. Create a Clear Policy: You should establish a written, consistent background check policy before hiring. This ensures fairness for all applicants and specifies which checks are needed for different roles, protecting your business legally.
  2. Always Get Written Consent: You must obtain signed, written permission from every applicant using a standalone document before starting a background check. This is a strict legal requirement under the Fair Credit Reporting Act (FCRA).
  3. Verify Work and Education History: Always confirm the details on a candidate's resume, such as previous job titles, dates of employment, and educational degrees. Many applicants are dishonest, and verification tools can help you spot inaccuracies quickly.
  4. Comply with Local Laws: You need to be aware of local and state regulations like "ban-the-box" laws, which dictate when you can inquire about criminal history. These rules are changing, so staying current is vital.
  5. Use AI with Human Oversight: While AI can speed up the screening process, a person should always review the results. This "human-in-the-loop" approach prevents unfair rejections caused by algorithmic bias or errors.
  6. Be Cautious with Social Media: If you check a candidate's online presence, avoid looking at protected information like age or religion to prevent discrimination claims. Using a third-party service can help filter out this sensitive data.
  7. Follow the Adverse Action Process: If you decide not to hire someone based on their background check, you must follow a specific two-step legal process. This involves sending a pre-adverse action notice first, giving the candidate a chance to respond.

Start With a Clear Policy

Before you post a job, you need a solid foundation for your screening process. This means creating a written policy that applies to every person you consider for a role. Consistency is the goal here. If you only check some people but not others, you might face legal trouble. A clear policy helps everyone on your hiring team understand what to look for and how to handle the data they find.

A recent blog post mentions that 80% of employers now perform these checks on potential hires. You should outline which checks are needed for specific roles. For example, a driver needs a motor vehicle report, while a financial officer might need a credit check. Setting these rules early keeps the process fair and professional for every applicant.

Get Written Consent Every Time

You cannot simply start digging into someone’s private history. Federal law is very strict about how and when you can gather this information. You must give the applicant a standalone document that explains you are running a background check. This cannot be buried in the middle of a long job application.

Once they have the notice, they must sign it to give you permission. Industry experts point out that the Fair Credit Reporting Act (FCRA) requires this written consent before any screening begins. If you skip this step, you risk heavy fines and lawsuits. It is a simple but vital part of staying compliant with national standards in 2026.

Look Into Drug Screening and Compliance

Keeping a safe workplace often involves checking for substance use. When you look into National Drug Screening and similar services, you find they offer ways to manage these tests while following all local laws. It is a common practice for roles that involve heavy machinery or sensitive data. Having a partner handle the testing ensures the results are handled privately and correctly.

Safety is a top concern for any business. You want to know that the people you bring on board are reliable and ready to work. Setting up a regular testing schedule for new hires can help reduce risks and keep your insurance costs lower over time.

Verification of Past Work and Education

Lying on a resume is more common than you might think. A survey from January 2025 found that 44% of job seekers admitted to being dishonest during the hiring phase. This is why verifying every claim is a high priority. You should contact past schools to confirm degrees and call previous bosses to check job titles and dates.

Use Modern Tools for Accuracy

Many offices now use automated systems to speed up this part of the job. These tools can quickly spot gaps in a work history or fake diplomas. An industry report notes that employment verification makes up over 62% of the revenue in the screening market today. Using these services can save your HR team hours of manual phone calls.

Understand Local Ban-the-Box Laws

The rules for checking criminal records are changing fast in 2026. Many cities and states have passed "ban-the-box" laws. These rules usually mean you cannot ask about a criminal past until after you have made a job offer. You must be careful to follow the specific rules in the area where you are hiring.

  • In Philadelphia, new rules starting January 6, 2026, limit how far back you can look at certain convictions.
  • Washington State will also start new requirements for medium and large employers in July 2026.
  • Virginia has "Clean Slate" laws that may cause some older records to be sealed and invisible to employers.

If a record does show up, you cannot always use it to say no to a candidate. You must look at the type of crime, how long ago it happened, and if it actually matters for the job. This is called an "individualised assessment," and it is becoming a legal requirement in more places every year.

The Role of AI in 2026 Screening

Artificial intelligence is a huge part of hiring today. It helps analyse data faster than any human could. A guide on 2026 trends explains that AI is changing how we look at both resumes and backgrounds to improve accuracy. It can find patterns in data that might suggest a candidate is a great fit or a potential risk.

However, you cannot let the machine make the final call. You should always have a person review the findings. This is often called a "human-in-the-loop" approach. It ensures that the technology is being used fairly and that no one is being rejected by a glitch or a biased algorithm.

Social Media and Online Presence

Checking what a candidate posts online can give you a peek into their personality. It might show you if they fit the company culture or if they have a history of bad behavior. Research shows that many employers find red flags on social media that lead them to skip a candidate.

You must be careful not to look at "protected" information, like someone’s religion or age. If you see these things online and then don't hire the person, they could claim you discriminated against them. Many companies now hire third-party experts to do these searches. The expert only reports the relevant, work-related info and leaves out the private details.

Handling the Adverse Action Process

If you decide not to hire someone because of what you found in their background check, you must follow a two-step legal process. First, you send a "pre-adverse action" notice. This includes a copy of the report and a summary of their rights. You must give them time, usually about 5 business days, to look it over and explain any mistakes.

After that time passes, if you still don't want to hire them, you send the final notice. This tells them the decision is official. Skipping these steps is one of the biggest mistakes a company can make. It protects the applicant's right to fix errors in their file and keeps your business safe from legal claims.

Two women sat talking

Doing a deep dive into an applicant's past is about more than just finding bad news. It is about making sure the person is who they say they are. In a world where fake resumes and deepfake identities are on the rise, these steps are your best defence. By following the law and using the right tools, you can hire with confidence and build a team that will help your business grow.

FAQs for How to Conduct a Thorough Background Check on Job Applicants

Do I really need a written policy for background checks?

Yes, a clear, written policy is essential. It ensures you apply the same screening process to every candidate, which helps you stay fair and avoid legal trouble. Your policy should detail which checks are required for different roles.

Can I run a background check on any applicant?

No, you must get explicit, written consent from the applicant before you begin any screening. This is a strict requirement under the Fair Credit Reporting Act (FCRA). The consent form must be a separate document, not hidden within the application.

What should I do if a background check reveals negative information?

If you plan to reject a candidate based on what you find, you must follow the legal "adverse action" process. This starts with sending them a pre-adverse action notice, a copy of the report, and a summary of their rights, giving them time to dispute any errors.

How do "ban-the-box" laws affect my hiring process?

These laws restrict when you can ask about a candidate's criminal history, usually delaying the question until after a conditional job offer has been made. The rules vary by city and state, so you must follow the specific regulations for your location.

Is it a good idea to check a candidate's social media profiles?

Checking social media can offer insights, but it carries risks. You must be careful not to view protected information like religion, age, or marital status, as this could lead to discrimination claims. Some businesses use third-party services to handle these checks safely.
