Reliability or the ability to learn or interpret something unique? You can continue by describing specific examples of challenges you have met and goals you have achieved in the past. Better still, you need a good ending. It is important to remember that reliability is not measured, it is estimated.
Selection systems that test for the competencies that actually predict job performance have much higher validity. Predictive validity is the extent to which a test or questionnaire predicts some future or desired outcome, for example work behaviour or on-the-job performance. Although three primary approaches to test validity are reported by Mason and Bramble 1989 , Patton 2002 details the associated sub-categorical types of measurement validity: 1.
