Within the framework of the theory of latent variables based on the Rasch model, the influence of the test shift on the accuracy of measuring the level of preparedness of the subjects is investigated. Situations are considered when the difficulty of the test corresponds to the proficiency level of subjects, as well as when the test is shifted relative to the level of subjects’ proficiency by one and two logits. It is shown that increasing shift, decreases the measurement precision of the latent variable.

The article presents the construction of a simulation experiment that allows to determine the influence of the number of gradations of indicators on the measurement precision. The data of the simulation experiment were generated taking into account their processing within the framework of the theory of latent variables. The initial data is generated for the most commonly used gradations – from two to ten.
