In this study, the predictive roles of perseverance and openness to problem solving on success in the lower and upper quartiles of score distribution are analyzed in scientific, mathematical, and reading domains of PISA 2012 Turkey sample. Since their index values can’t be calculated due to missing values, some students are excluded from the sample. The study sample is comprised of 3,190 students. Regression models in which perseverance and openness to problem solving are predictive variables and success is response variable are formed for the lower and upper quartiles of score distribution of each domain. Models are analyzed by quantile regression analysis. It is found that there is a positive, medium level, significant relationship between perseverance and openness to problem solving. The results of quantile regression analysis show that perseverance predicts success better in the lower quartile of score distribution while openness to problem solving predicts success better in the upper quartile of score distribution in all domains. Based on these results, suggestions regarding classroom activities, assessment processes and feedback given to students are discussed respectively.
