Twenty questions about employment testing bias and unfairness in the Netherlands

This chapter examines bias and fairness in employment testing in the Netherlands, addressing twenty key questions related to historical and cultural developments, legal frameworks, professional guidelines, and psychometric issues. Although equal treatment is a fundamental legal principle, perceptions of hiring discrimination remain widespread. The chapter explores demographic shifts that have shaped discussions on employment fairness and outlines the Dutch legal framework, focusing on the Equal Treatment Act and the role of the Netherlands Institute for Human Rights in handling discrimination complaints. It also highlights the relatively limited attention given to fairness in professional guidelines for practitioners. Furthermore, the chapter evaluates how psychological tests are assessed for bias, particularly through analyses of score differences, differential item functioning, and measurement invariance, while noting the scarcity of research on predictive bias. Emerging challenges, such as algorithmic bias, are also examined. Finally, the chapter discusses recent legislative efforts to promote fairness in employment testing, including a proposed law that was rejected in 2024.
