Calculation method problems of KPSS P10

KPSS Licensing exams are administered annually; the scores are valid for two years. For this reason, the equivalence of the examinations is important. This study has aimed at analyzing the calculation techniques. Certain problems have been found with the calculation. The comparison of the received scores between the previous year and the following year becomes risky as the overall points are calculated by applying a conversion to the grades which are reached after the group internal ranking of the individuals’ standardized grades. The points obtained by this method are affected by the points of the highest scored candidate, by the performance of the individuals not taking any one of these tests, and by the degree of the heterogeneity and homogeneity within the scores of the examinees. In addition, the impact of two sub tests, general ability and general culture is more than the predicted; on the other hand the impact of sub test of the educational sciences is lower than the predicted in the P10 test scores. In the study, some suggestions were made in the light of these findings
