IB Diploma Programme Assessment

Students take written examinations at the end of the Programme, which are marked by external IB examiners. Students also complete assessment tasks in the school, which are either initially marked by teachers and then moderated by external moderators or sent directly to external examiners.

The marks awarded for each course range from one (lowest) to seven (highest). Students can also be awarded up to three additional points for their combined results on theory of knowledge and the extended essay. The Diploma is awarded to students who gain at least 24 points, subject to certain minimum levels of performance across the whole programme and to satisfactory participation in the creativity, action, service requirement. The highest total that a Diploma Programme student can be awarded is 45 points.

Assessment is criterion related, which means student performance is measured against pre-specified assessment criteria based on the aims and objectives of each subject curriculum, rather than the performance of other students taking the same examinations. The range of scores that students have attained remains statistically stable, and universities value the rigour and consistency of Diploma Programme assessment practice.

The ACT Senior Secondary System caters for students in Years 11 and 12, generally aged between 16 and 19 years and is based on the principle of continuous assessment throughout Year 11 and 12. A student qualifies for the award of a Year 12 Certificate on completion of an educational program approved by the School. Students who wish to go to University need to complete a Tertiary Package, and sit the ACT Scaling Test (AST), to receive an Australian Tertiary Admission Rank (ATAR).
