However, the analysis reported here suggests that this trend can be misguided: the time students spend in the classroom is not always positively related to their academic achievement.…

International large-scale assessments of achievement often have a large degree of differential item functioning (DIF) between countries, which can threaten score equivalence and reduce the validity of inferences based on comparisons of group performances. It is important to understand potential sources of DIF to improve the validity of future…

But even instruments in a single language may be biased towards certain countries or regions due to local linguistic specificities. Consequently, it may be appropriate to use different versions of an…
