We describe preliminary data from two studies aimed at investigating the psychometricproperties and validity of newly developed measures of morphologicalknowledge and skills in Russian, namely, the Word Structure subtest, and the Testof Morphological Awareness, in two samples of young Russian-speaking children.Overall, both instruments demonstrated good psychometric properties when analyzedusing both classical test theory and a Rasch-modeling IRT approach, andwere positively associated with the criterion measures (i.e., the number of grammaticalerrors in elicited speech samples, spelling, and reading comprehension).
