When enlisting an assessment tool to help you make better hiring decisions, or to aid in coaching and development, it’s important to ensure the tool is based on sound science. The idea of talent assessments (also called behavioral assessments, personality assessments, psychometric testing, pre-employment testing) is grounded in decades of industrial psychology. The science behind these tools has been well established and proven.
Reliability refers to the degree from which test scores are free from measurement errors.
Validity refers to how well the measured personality traits correspond to the person’s actual personality. In each case, there are testing models that should have been used to confirm this information.
In addition, your assessment should be compliant with the guidelines set by human rights' regulatory bodies such as the Equal Employment Opportunity Commission (EEOC).
