Abstract
Comparability of paper and online versions of a statewide assessment was evaluated for the purposes of test score reporting, to appropriately adjust equated score conversion tables for students testing online as warranted. In particular, comparability of online and paper tests was designed with a propensity score matching method. The propensity score was used to match the online test sample with the paper–pencil test sample. The results of this study suggest that neither a separate assessment nor a conversion table would be required in a state’s assessment. The online test appears to provide a credible and comparable option to the paper and pencil modality.
