In large-scale assessments, it usually does not occur that every item of the applicable item pool is administered to every examinee. Within item response theory (IRT), in particular the Rasch model (1960), this is not really a problem because item calibration works nevertheless. The different test booklets only need to be conceptualized according to a connected incomplete block design. Yet, connectedness of such a design should best be fulfilled severalfold, since deletion of some items in the course of the item pool's IRT calibration may become necessary. The real challenge, however, is to meet constraints determined by numerous moderator variables such as different response formats and several topics of content--all the more so, if several ability dimensions are under consideration, the testing duration is strongly limited or individual scoring and feedback is an issue. In this article, we offer a report of how to deal with the resulting problems. Experience is based on the governmental project of the Austrian Educational Standards (Kubinger et al., 2007).
