Employers may ask a consumer reporting agency (CRA) to implement internal systems to evaluate background checks as part of the hiring process. An adjudication matrix (also known as a hiring matrix) is commonly used by employers to designate what types of crimes over certain time periods may make an individual ineligible for employment. An adjudication matrix will typically contain labels such as “clear” or “ineligible” that designate how the individual’s background check results lined up with the matrix.
