?:abstract
  • PIAAC is one of the first internationallarge-scaleassessments that implemented a multistage adap-tive testing (MST) design. The design consists of multiple layers of adaptation to administer the most relevant and efficient set ofquestions based on the estimated proficiency of respondents. The benefits of the MST design were evaluated in terms of the comparability of item parameters across countries and the test efficiency. To assess the comparability across countries, item-by-country interactions were examined using item response theory (IRT) models. The efficiency of the MST design was calculated and compared to a nonadaptive design with a fixed item format.Moreover, possible effects of the position of item sets on item difficulty, which would present a problem for implementing MST, were examined.Results show a higher test efficiency in the MST design, only small item position effects and a high comparability of item parameters across different countries and languages.
