It also develops tests for assessing different competence domains. In order to evaluate the quality of these competence tests, a wide range of item response theory (IRT) analyses were carried out. This paper describes the data and results of analyses of the biological competence test that was used in the additional study Baden-Wuerttemberg. The test was based on a subset of items from the EVAMAR II test (Eberle, et al. 2008), which was also administered in the additional study Thuringia. In sum, 4,882 students took the biology test in these three waves. The biology test consisted of 60 items, representing different content areas (e.g. cytology, genetics, ecology). A partial credit model was used to scale the data. Item fit statistics and differential item functioning were investigated. The results showed that the items exhibited good item fit and measurement invariance across various groups. However, the reliability was moderate. The paper also provides some information about the data available in the Scientific Use File, ConQuest- and TAM-syntaxes for scaling the data, and appendices that describe the scaling of each wave separately.
