Here are the most commonly used background check services in pre-employment screening.nnCriminal History: One of the most basic checks is reviewing a job candidate's criminal history, if there is one. Some positions legally require a criminal background review. Even when not required, it's often worth conducting to increase workplace safety.nnEmployment History: Employers want to ensure an applicant's listed employment history is true and accurate. Not only do you want to confirm the applicant worked at the places they list, but you want to check the dates are correct and that the employee didn't leave off any previous employers. For example, an employee might have worked for a competitor. Some employment history checks will also indicate if the employee was terminated due to unethical or inappropriate behavior.nnEducational History: Much like employment history, employers should verify that a job candidate attended and graduated from the schools listed in the résumé or application.nnWork Eligibility: Businesses should confirm that an employee's work status allows them to work for the company.nnSocial Media Activity: Social media has become essential to how people present themselves to the world. You should know if a candidate has engaged in hate speech, discriminatory language, or other offensive behaviors online, which will disqualify them from employment.nnCredit History: Some companies want to see if a candidate has excessive debt. This is of particular interest for positions where an employee has access to corporate funds, handing cash, or sensitive information. High levels of debt could be a significant red flag for those positions.nnDriving History: Positions that require an employee to drive as part of the job should verify the employee has a clean driving record. Not only would a poor record make the employee a liability, but it could also drive up your insurance costs.nnMedical Screening: Businesses offering jobs that require physical strain, such as warehouse workers, construction, landscaping, etc., want to ensure the candidate doesn't have health issues that would prevent them from performing the essential tasks of the job.
