If an organization faces a prima facie case of hiring discrimination, it must prove that the basis for the selection decision was job related. This can be done by: a. establishing the validity of the selection instrument used in the selection process.b. conducting a study to validate the ethics and culture of the organization.c. demonstrating that the selection decision was based on the age and seniority of the applicant who has filed the lawsuit.d. reconducting the employee selection test using the same selection instrument that was used in the original selection process.
