A background check typically involves an investigation into a candidate's history based on criteria selected by the employer, which may include class-specific searches that disclose information specific to that category and carry its own criteria for validity. Background checks are often used during the recruiting process to confirm information regarding a candidate's application, but they can also be performed during an employee's tenure to confirm requirements continue to be met. The frequency of rescreening depends on various factors, including job duties, access to financial data, and changes in employment status. While there is no federal or state regulation requiring rescreening every two to five years, some industries may require more frequent checks due to the nature of the work. Continuous background checks, such as Continuous Crim and Continuous MVR, can provide real-time updates on a candidate's criminal records and motor vehicle records, allowing employers to make smarter hiring decisions and protect their brand reputation. Ultimately, the goal is to ensure that all candidates receive a fair opportunity at employment while maintaining the employer's responsibility for verifying information about new hires.
