A criminal history background check is typically conducted by many law enforcements or employers to verify someone"s criminal history. A full criminal history report will list every arrest, charge, conviction and acquittal you have ever had. Basically, criminal background checks are primarily used by law enforcement and the courts to determine an individual"s criminal history for charging or sentencing purposes. Lately, employers, landlords and other organizations have begun using them to ensure that they are not hiring or housing dishonest or violent criminals. Also, background check reviews  are a common use by many employers to evaluate potential employees as these reports can turn up information about a person"s criminal past, and knowing what they can or can"t show can be important for a job seeker.
