This depends on a variety of factors, not the least of which includes the goals and budget of the employer (e.g., search speed vs. breadth/depth, budget, etc.). Criminal record searches generally are at the foundation of an employment background check - due in substantial part to protect its workforce and prevent against negligent hire claims. Searching the county courthouses in the areas where the person has lived is an industry best practice. In addition, various database searches can be conducted to identify additional jurisdictions in which it may be advisable to search the applicable courthouse, and Federal level criminal record searches also can be performed. Beyond criminal records searches, additional screening options may include Motor Vehicle Records, Employment and Education Verification and drug testing.
