The results of numerical experiments confirmed the consistency of maximum likelihood estimates of the latent parameter «difficulty of the task» Rush's dichotomous one-parameter model at the fixed number of tasks of test L of identical test difficulty and indefinitely increasing the sample size of students N. It is shown, that under the same conditions of estimation of level of preparation of n-th student, calculated from the permissible dichotomous response matrix, tend in probability to their original estimates .
