Abstract

Final test was applied to a group of 270 students from 7 th and 8 th grades.As a result of the analysis of the data obtained, information was received on the test-level fit statistics, item parameters, posterior probabilities of latent classes, and the latent classes to which the students are included. The mean of g, s and δ parameters of the final test were calculated respectively as 0.39, 0.26 and 0.34.Psychometric characteristics of the developed test was compared with the other studies in the literature, thus it was determined that the compatibility of the test with the subject area is high and that the parameter values are adequate.
