In the course you will learn how to evaluate and use tests and questionnaires in research and assessment, especially, in recruitment and personnel selection. You will learn to understand personnel selection methods, to check whether instruments are reliable, and to check whether those instruments measure what they are supposed to measure. You will learn what kinds of instruments are used in assessment and research and what requirements measurement instruments need to satisfy (e.g., by professional associations). You will analyze the reliability, validity, utility, and adverse impact of measurement instruments. Importantly, you will also learn how to use multiple instruments to make important workplace decisions such as whom to hire, fire, and promote. Furthermore, you will learn about state-of-the-art research on algorithmic decision-making in individual diagnosis.
