Keyword: «test shift»

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.
