摘要：The main purpose of this article is to present a Differential Item Functioning method
of item analysis. It is designed to minimize the discriminatory effect of individual items
in the accreditation of graduates of medical universities with different training
programs. The one-parameter Item Response Theory model is used to align graduates’
rights in accreditation. The measure of the difference in the location of the item
characteristic curves constructed for different graduates’ samples is presented using
the difficulty estimates. For the development of the methodology, a number of
research questions are posed, the solution of which made it possible to analyze the
items bias for the “Polyclinic” discipline and the range of item difficulties from 1.5 to 2,
5 logits. The item bank was cleaned and an interpretation of decisions on items release
and correction for the cases of different arrangement of their characteristic curves was
presented.
