The purpose of this study was to determine the relationship between the means of students’ academic grades and their ÖSS scores. To achieve this, the mean of student academic grades has been treated as a cluster variable and their ÖSS points as another cluster variable and the multiple relationships between the variables were analyzed by the Canonical Correlation analysis. As a result of this research, it has been thought that useful information has been obtained about predictive validity of ÖSS and degree of relationship between high school academic grades and ÖSS scores.
