At the end of the programme, students take written exams, which are marked by external IB examiners. Students are also subject to internal assessments at the school, which are assessed by the teachers and later reviewed by external moderators, or sent directly to external examiners.
The subjects are graded ranging from 1 (lowest grade) to 7 (highest grade).
Additionally, the results of Theory of Knowledge and Extended Essay are combined, adding up to three additional points to the diploma’s total score. The diploma is awarded to students who earn at least 24 points, subject to certain minimum levels of performance across the whole programme, and satisfactory completion of the requirements in Creativity, Activity and Service. The highest total score that a student can be awarded is 45.
The assessment is based on criteria, which means that student performance is measured against the established assessment criteria related to the general and each subject’s specific goals, and not against the performance of other students who take the same exams.
Statistically, the range of scores obtained by students has remained stable and universities value the rigour and consistency of the Diploma Programme assessment practices.
Students may choose to take only a few subjects, rather than the entire programme. In these cases, the students receive a certificate for the subjects they pass. In the School, students may only attend one independent CAS subject, obtaining a certificate that may be attached to their academic experience.
