The aim of the work is to modify Rasch model and to justify this modification. The task of the work is the creation of a new method and algorithm for processing test results. Studies include comparison of normative and free testing. The paper provides critical analysis of Rasch model in education. Studies reveal the difference between the conditions of testing in education and psychology. The article recommends the transition from individual evaluation of testing to comparative evaluation. In this case, testing should be supplemented with estimates from the theory of preferences. The proposed method excludes the influence of one latent variable in Rasch model. This raises evaluation quality. The result of the work is a new method and algorithm for evaluating the results of testing. The method allows to carry out group analysis and compare the results of free testing. The method allows making a comparative assessment of the quality of students preparation by different teachers.

Key words: Education, testing, regulation testing, free testing, Rasch model, comparative evaluation, algorithm, theory of preferences.
