The accuracy of estimation procedures based on the imputation of plausible values

In large-scale international educational surveys, such as TIMSS and PISA, data are often collected using complex item administration designs. Usually, Item Response Theory (IRT) models are used to compare the students' performances in such incomplete designs. In many instances, countries want to use the measurements for secondary analyses. One could, for instance, be interested in the relation between achievement in mathematics and predictor variables such as SES or IQ.
