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 aim of the work is to determine the precision of measurement of latent variables. A comparative analysis of the classical theory of testing and the theory of latent variables is given. The study is based on a simulation experiment within the framework of the theory of latent variables.
