​​All principals, teachers, administrators, staff (including paid staff and volunteers with staff responsibilities), and coaches (including paid and volunteer coaches) who work at an elementary school or high school must be fingerprinted under the California Education Code and pass a background check before they commence any assignment. Preschool personnel and volunteers must be fingerprinted under the California Health and Safety Code and pass a background check before they commence any assignment. All fingerprints are submitted to the California Department of Justice and the FBI. Traditionally in the archdiocese, the principal of the school has been the confidential reporter of criminal offender record information​ (CORI reporter) but the archdiocese is transitioning the CORI reporting to the Fingerprinting Office.
