PSI has developed several suggested test batteries which you can use, or you may customize your own battery. In selecting tests for your battery, be sure that the chosen tests measure skills that are important in the job. In many situations it is suggested that a four-test battery be considered. On the basis of job analysis and validation work, PSI developed test batteries which test required abilities in the context of tasks performed on the job. Combining ability and attitude measures can maximize the overall validity of your selection process.
Research literature indicates that the highest overall validity is achieved by using both.
Adding an attitude measure such as ViewPoint to a battery of cognitive measures can mitigate adverse impact. A. PSI most often suggests that test scores be interpreted by using appropriate norm tables and selecting candidates whose profiles best match job requirements. Used in this way, the test information may be integrated with other information gained during the selection process and the hiring decision made on the basis of all information available. A. Norm tables enable you to compare your job candidate's test performance to that of a sample of individuals performing similar work to that being applied for. A percentile indicates the individual's relative position in a group.
