Some assessment tasks are conducted and overseen by teachers without the restrictions of examination conditions, but are then marked externally by examiners. Examples include world literature assignments for language A1, written tasks for language A2, essays for Theory of Knowledge and Extended Essays.
Because of the greater degree of objectivity and reliability provided by the standard examination environment, externally marked examinations form the greatest share of the assessment for each subject.
The grading system (1-7) is criterion based (results are determined by performance against set standards, not by each student’s position in the overall rank order). Validity, reliability and fairness are the watchwords of the Diploma Programme’s assessment strategy.
