There are stark variations in the achievement distributions in Slovenia between paper and pencil Matura exams graded externally compared to Matura coursework and oral exams in schools graded internally. The extremely high average scores for internal grading of Matura subjects' coursework and upward annual trends are presented in this paper. The differences in the distribution of three pairs of achievements for some schools in comparison to the entire country are also shown with an ordinal dominance graphs: for teachers' grades before Matura exams, for externally graded paper and pencil exams and internally graded Matura subjects' coursework. Very different distributions for external and internal grading in schools are disturbing and unjust. Grading in the end of Gimnazija program must also discriminate and show differences among Matura candidates according to achieved goals and standards. It is shown that as a rule, high achievement for the external parts is followed by low achievements for the internal parts and vice-versa. Since there some important learning goals that cannot be assessed using paper and pencil tests but can however be assessed using coursework, the possibility for change is outlined in this paper, suggesting that internally graded coursework and oral exams should also be externally moderated.
