Psychometric analyses of IDP 2016

Every year Flemish Catholic primary schools can take part in a large-scale assessment with their sixth-grade students in order to get school feedback with respect to their performance. The present study investigates the psychometric qualities of the tests of mathematics and Dutch that were administered in 2016. More specifically, it was investigated whether there was a test mode effect (paper-based versus computer-based test administration) and to what extent school differences were found.
