Measurement of competencies in science is an important tool to inform school administrators and educators about the status of the school
system and a realistic view on mean student abilities. As consequences there might be changes in the curriculum or the standardization of
the national education standards. The content used in the items for the assessment defines the subject which is measured and influences the
item difficulty. Therefore the role of content for the assessment needs to be discussed. In this chapter authors from two large assessment
projects in Germany and Switzerland present the respective assessment and how content validity is ensured and the content’s influence on
difficulty is investigated. The first two authors briefly introduce to the assessments’ frameworks. The following two authors report about
research studies conducted within the second assessment project.
