Abstract: This paper focuses on the predictive validity of the upper secondary grade point average (GPA), when used as selection instrument to higher education. The purpose of the paper is to find out if the predictive strength of the GPA is affected by time, here measured as the time that has passed between when the grades were received (graduation) and university entrance. The data includes approximately 5 900 students admitted to a Business administration or an Economics programme in a Swedish university between the years 1993 to 1996. The predictive validity is studied by correlating the GPA from upper secondary school for the students from each age group with their academic performance, measured by university credits. The results show that there is a weak positive correlation between grades and university credits, but that the predictive strenght decreases with time, to be insignificant about three years after upper secondary school completion. Implications are discussed.
