Some of the factors that can disqualify you from a level 2 background check are:
Criminal history
Education and credential discrepancies
Damaged driving record
False employment history
Failed drug test
Denying a job to an applicant with a criminal history might be considered discriminatory. However, it may be acceptable if they have to work with vulnerable people.
Similar to level 1 background check disqualifying offenses, if a candidate exaggerates their education history, it means they can’t be trusted. The same applies if the applicant is dishonest about their employment history. If such information is revealed, they most certainly will fail the level 2 background screening and can be denied the job.
For persons whose job requires driving, having a damaged driving record show up on the background check is a deal-breaker. The damage can be a speeding ticket or a DUI charge.
This also applies if the results of a drug test indicate the applicant used an illegal substance. However, exceptions can be made depending on local laws.
