ESR performs state based criminal record searches where available directly from the agency legislatively designated to maintain those records.
Note that there are only a few states that meet the best practice standard of courthouse searches largely due to state records being incomplete, not having identifiers or records not being updated (at least on a monthly basis). Where state records are not courthouse equivalent, they are suitable as supplemental to expand the level of due diligence but not sufficient as a stand-alone criminal search. There are also states that do not make state repository records available to the public without a regulatory requirement. In states with a unified court system (equivalent to a hands-on search) the statewide system may be used in lieu of individual county searches enhancing the scope and thereby increasing the level of due diligence.
Wise use of statewide records based on what they actually provide can be part of an effective part of a safe hiring program.
