Relationships Between the Scores of OYS and OSS Administered in the Two-Stage System During the Entrance to University

Abstract

This study aims at investigating the relations between the scores of the Student Selection Examination (OSS) and the Student Placement Examination (OYS), which were administered to the students entering university at a nationwide level as two successive stages. The Student Placement Examination was abolished in 1999 and since then the Student Selection Examination has become a one stage tool to achieve the goals targetted by the two examinations. In this study the validity of the OSS was investigated taking the OYS as a criterion to determine the effect of this change in the examination system on the achievement of the goals of the student selection and placement process. In the study the OSS and OYS scores of 38769 candidates, who passed OYS, taking the OSS in 1998 are considered. A Simple Linear Regression Technique was used to determine the predictibility degree of OSS scores to OYS scores. At the end of the study, significant similarity was found between the scores of the numerical and verbal sections of ÖSS and the related tests of OYS. However, no significant evidence is found to prove that this similarity provides sufficient grounds to abolish the OYS.
