Educational Measurement

The working unit Educational Measurement focuses on the measurement and analysis of psychological characteristics. This includes, among others, the assessment of latent (unobservable) traits, particularly with computerized instruments in educational large-scale assessments. 


The working unit is responsible for scientific and infrastructural tasks related to psychometric test evaluation, development of test designs, and implementation of computer- and web-based testing procedures in the National Educational Panel Study (NEPS). The subunit Scaling and Test Design primarily deals with the evaluation of the test quality of psychological instruments used in the NEPS and the publication of the corresponding data. In addition, novel test designs are developed to capture psychological characteristics more efficiently. 


The members of the working unit conduct independent scientific research in the fields of psychometrics and (technology-based) psychological assessments. This includes, for example, research on modeling latent characteristics in longitudinal settings or the validity of web-based testing. Detailed information on the research topics can be found on the pages of the individual members of the working unit.
