Özet:

Abstract In this study, the materials belonging to the Turkish sub-test of the OKS (Middle Education Institutions Examination) were analyzed according to the classical test theory (KTT) and the cover characteristics theory (ÖÖT). The purpose of the research is to reveal what a relationship is between the material statistics cutting according to the KTT and OET. The study used the OKS Turkish subtest as a data collection tool and the research was carried out on 553108 students who took this exam. After the data collected was first tested whether it could not meet the assumptions of the OET, the statistics of the matter and the parameters of the matter were cut by the help of the BILOG and ITEMAN programs, according to both theories. Spearman Brown then used the correlation ratio of the differences in order to determine the relationship between the parameters and statistics of the substance cut according to both theories. The findings obtained from the study have shown that the parameters and statistics of the substance cutting based on the two indicated measurement theories of the OKS Turkish subtest are very similar.
