Abstract

The purpose of this study is to determine the factorial structure of Secondary School Institutions Student Selection and Placement Test and Which factors is reasonable enough to predict the academic level secondary school institutions. In order to achieve this, the factor structures of OKÖSYS have been determined by analyzing the sample data from 10.000 individuals chosen randomly from 83.307 individuals who passed the exam that was held in country-wide in 1999. Eight structures have been found after factor analysis. After that, it has been investigated by using stepwise regression analysis which factors can predict the achievement of 9th grade. As a result of the research, it has been found that 28 % of the academic achievement of the first grade in secondary school had been explained by almost all of the higher order thinking skills that were measured by the test.
