According to the PCI CPSA Qualification Requirements, one of the administrative requirements for CPSA Companies is to retain all applicant and employee background information on file for at least 12 months after termination of the contract of employment. This is to ensure that the CPSA Company can provide evidence of the background checks performed on the CPSA Employees or other personnel involved in card production and provisioning activities. The background checks should include criminal history, employment history, education verification, and reference checks, and should be conducted at least every two years or upon rehire. References: PCI CPSA Qualification Requirements, Version 1.1, April 2020, Section 6.1.2, Page 111
